I've started a project to create a list of 3D-capable projectors. All tests were done on a Toshiba M30 notebook with buildin Geforce FX 5200 Go graphics card, NVIDIA's consumer stereo driver and Stereoscopic Player. Here are the first results: Infocus DepthQ projektor (800 x 600, DLP, 1600 ANSI Lumen): 60 Hz: yes 75 Hz: yes 85 Hz: yes 100 Hz: yes 120 Hz: yes Benq PB8120 (800 x 600, DLP, 1800 ANSI Lumen): no Benq PB8140 (800 x 600, DLP, 2000 ANSI Lumen): no Toshiba TDP-S20 (800 x 600, DLP, 1400 ANSI Lumen): 60 Hz: yes 75 Hz: yes (color problems) 85 Hz: yes (color problems) 100 Hz: no 120 Hz: no At 75 and 85 Hz, the image of one eye looks geenish, the other one blueish. This is not caused by the shutterglasses because it is also noticeable when not wearing glasses. Toshiba TDP-MT500 (1024 x 768, DLP, 700 ANSI Lumen): 60 Hz: yes > 60 Hz: no Panasonic PT-AE 700 E (1280 x 720, LCD, 1000 ANSI Lumen): 60 Hz: yes > 60 Hz: no Sim2 Domino 18H (1024 x 576, DLP): no If you have tested other projectors, please tell me. I'll create a website and summerize the results so that other people don't have to test all projectors again... | ||

Tried pageflipping with the Infocus X1 at 1024x768/60Hz. Cropped pic but works very well with amazingly no ghosting and slightly noticable flicker. However, I'm using a cheap Nvidia card and stereo occasionally drops out and the video is sluggish. Time for a new card. | ||

Infocus X1a, DLP, 800 x 600, 1100 ANSI Lumen 60 Hz: Yes 75 Hz: Yes (slight color problems) 85 Hz: Yes (slight color problems) Color problems are not a major issue (to me). I noticed the color problems (one eye perceives a slightly different color than the other) can be swapped when tinkering with advanced timing options. Geert | ||

Just to clear something up on this thread, I have just purchased an Infocus X1a projector. I have had it working in pageflipped stereo at 60Hz, 75Hz and 85Hz. As mentioned above, at 75 & 85Hz there is a slight colour distortion. However, if this is putting some people of buying this projector, I would just like to clarify that this colour distortion is VERY SLIGHT and is far less distracting than the flickering at 60Hz. Flickering at 85Hz is ALMOST undetectable, unless you are viewing in a brightly lit room, which is far from ideal for viewing 3D anyway! In summary, the X1a is ideal for viewing large screen 3D on a budget. If, however, you are a perfectionist, then save up and get the DepthQ. | ||

I just purchased an Infocus LP290. It runs good at 60/120Mhz 800x600. I notice a little flicker but only if I try to see it. I had to down the 3D image displacement to 5% because of the large screen. My only problem is it seems to display a flat image about every 15 frames. I don't know if the progressive/deinterlace video feature is doing this and/or if I just need to continuously tinker with the stereo modes and refresh rates. Anyone with an Nvidia card and Infocus projector I'd be interested in knowing every setting you are using for both the projector/monitor/card/timing to make it work properly. I'll post my settings if I can ever get it right. After at about 2 hours of trial with error and $650 in the hole I'm very frustrated. | ||

Hello, I guess I'm the only DIY 3D projector person left, everyone else decided to waste their money on the DepthQ. I just wanted to say most any of the cheap projectors can create stereo 3D as long as you know the refresh rate of the projector and set your monitor to the same or double that. Even the cheapest projectors have a 60mhz refresh. Setting the monitor refresh to 120mhz would definately eliminate any flicker and still sync with with the glasses, so with a $400 projector from eBay and a $30 stereo card w/ glasses you have it all. I don't know why everyone insists on the X1a, the refresh rates are slow and lumens low, the only benefit is the life hours that is if you then half your already low lumens, then the shutter glasses will only worsen that problem. You can get other infocus models cheaper that have refresh rates up to 100mhz not that it matters, 1700 lumens, or other brands at 2200, so I guess really what is the point of making a list and how is it that you make some models not work unless the progessive mode is messing it up and why buy an X1a then say it is a great deal and what is the point of a forum nobody reads ever? | ||

Who Read This: All projector declaring higher than 60 Hz refresh rate usualy downscales higer one to 60 Hz (with some expception working partialy to 85 Hz but producing color desync) = no stereo. None of the cheap projector can from pricipal reasons work at 120 Hz (I was participation in DepthQ development, I know what I speak about). | ||
| Who Reads This? Rating: N/A |
I never said the projector would sync at 120Hz just the glasses, 2x's the speed catches the same frames as 1x, 4x, 8x etc. We DIY people do it with the cheap projectors all the time to prevent the headaches, just check the other 3D forums out there, yeah the projector downscales to 60hz but that's not what you see blinking in the 1st place, it's the glasses cause each lens would blink at 30 if you set the timing to 60, common sense tells you that, and for most humans 30 is to slow for comfort but only because both eyes aren't seeing the same image at the same time creating what seems to be 15hz on the eyes (ouch!) although any tech would claim differently including myself because it actually is still at 30hz. Downscales don't mess anything up as long as the monitor setting is an exact multiple of the refresh rate on the projector, that is true at least until stereo projector companies smart up and make the refresh rate random rather than static, then people like the developers of DepthQ would get a few more sales from people like me who would have no choice or companies could just pick a random unpublished refresh for each screen size making it virtually impossible to guess since nVidia's drivers let you pick the refresh to a 100th of a degree. Even if all of us cheapos got together we'd never be able to produce the correct setting for every projector out there, so don't worry, you'll still get your money selling toys to the rich, meanwhile the handful of us who know better will continue playing our games in stereo until it becomes affordable for everyone else to join us, I'm not saying DepthQ isn't an excellent product, because it works great, a lot better than my junk (literally) but it's just too darn expensive for me and my buds right now. But there is something I don't exactly know that you can explain. How it is that there are color problems on some projectors unless one wheel spins at a different speed than the other, that's not right in the 1st place, it's a projector problem, not a compatibility problem, 60hz should be 60hz not 60-60-60-75, that's false advertising, I guess the reason most projector companies have stopped publishing exact rates already, more money to ya, I'm happy though, good luck DIY's and to you too M.H., thanks for the response :-) | ||
| clyde Rating: N/A |
interesting... what I cant understand, is how you can have 120hz on yr monitor and 60 hz on yr projector at the same time? Or - what you are saying is that the projector should be capable enough to "accept" the 120hz signal even tho it scales it down internally to 60? even so I'm sceptical about the flicker being reduced by this method, but I havent tried yet. _Regards | ||
| Peter Wimmer Rating: N/A |
"Who reads this", I cannot follow your explanations. Whenever a projector downscales to 60 Hz, you get 30 Hz plickering per eye. There is no workaround. > any of the cheap projectors can create stereo 3D Wrong. See first posting for projectors which do not work at all. (Of course you might be able to use them with passive systems, but this discussion is about pageflipped 3D). | ||

Here is a compatibility list of many more projectors: http://www.razor3d.de/positivliste.asp | ||
| M.H. Rating: N/A |
My opinion abou the razor3d table: Most of the listed projector will work somehow only at 60 Hz. I do not belive the table is based on true testing of the projectors for stereoscopic usage - it is probably based only on the manufacturer informations = higer frequency will not work or they will be out of phase. P.S. InFocus DpethQ work up to 120 Hz not only up to 100 Hz as listed in the table (and it works on all lower frequences)... | ||
| Unclebob Rating: N/A |
Peter great find. But I see the Infocus X1 there which I have. 3D is great only when fed at 1024 in native mode, this however gives a cropped image as the projector can only do 800*600. Not that brillient. Every other resolution and frequency there is significant ghosting. Awaiting some news on the X3 as that DLP chip is 1024 and some reports have been favourable. So unfortunately that list may not be as accurate as it could be.. Sorry to bring a downer on it but if one that is listed doesn't work well then what of the others??? Hate to see someone shell out the cash and end up dissappointed. All the best Unclebob | ||

It's been a while since i posted after burning up the bulb on my x2. Well, I broke down and bought the x3 today since circuit city is selling it for $874 after rebates (Great Deal!). 3D performance wise, it appears to function just like the x2, which is great! Just finished playing a little painkiller and it is stunning at 1024x768. 75 hz refresh works with slight color issues but it isn't a big deal with painkiller since it is such a dark game anyway. More to come on other games once i have had a chance to play a little more. Great to be able to play in stereo again on the bigscreen! PiXeL | ||

Hey thanks for the feedback! I am looking for the X3 also. I have an x1 right now but i want more resolution and correct 3D. Can you get it to work at 85hz? And how is the projector overall for films, it is better than the x2 or x1? Thanks for taking time | ||

I've bought an LG BX220. It works with pageflipping between 60 and 85 Hz. In 85 Hz, there is a slight blue tint to the colour of one of the eyes. ...it could be a nice feature if nVidia's stereo driver could allow colour tweaking for separate eyes - then you could get rid of the blue tint. /Alex | ||

Too happy getting a new projector I guess I was a bit too quick posting about it. Trying to play I have noticed it does have a one frame delay (how do I get rid of this?), and also the green in the picture is gone for some reason when I insert my edimensional dongle. Can't see anything visually wrong with it, and It does work on my other CRT monitors.  Oh well, everything can't be so perfect after all. I can live with the missing green if I can figure out how to swap the left/right. | ||

Hi, the simplest way for reverse is reverse glasses usage (up is down), simple and easy. The other way is "reverser" (1x 3,5mm jack female and 1x 3,5mm jack male and 5cm of 3 wires cable with the change of 2 no ground wires - this is my future plan). | ||
| Peter Wimmer Rating: N/A |
If your 3D application doesn't allow to swap left/right you could solder an adapter which exchanges left and right signals. | ||

Hi, today I tested Benq PE 7700 (DLP,6 segm.wheel,5x wheel speed). Interesting this supermachine had no normal VGA input - is possible VGA signal usage only per adapter (R,G,B,W signal). No 75,80 Hz, absolutly no synchronisation and no stereo. I had only 1 hour for test, i have changed res. and refresh. No succes. Possible good Benq is new MP 720, only zoom is lower vs PB 6240. I think my definitive choice is 6240. (Good stereo, and price). | ||

Hi, Benq PB 6240 news:yesterday is my new projector arrived. Max refresh:real 86Hz stereo in 1024x768 ! No ghosting, No flicker, with e-dimensional e-glasses, 1 frame delay is no problem (change of L/R vires from glasses by one switch). Only little, little color L/R difference, absolutly no problem in stereo. Picture is absolutly sharp and 2700 ANSI is sufficient for 3d stereo 3m diagonal on simple white wall with reserve of lumens. Great Benq. The projector is 4 segment wheel, 2x speed, is 2005 model,the price is very good. | ||

Peter, can't change left right wires with H3D dongle for H3D wireless glasses as left and right is sent down one wire as serial data. It has 3 wires to the infrared sender. +5V, Ground, Left+Right serial data as the 3 wires. Is their a solution? | ||
| Hornet Rating: N/A |
I thing yes, I hope the L/R change result is the change of L/R open/close status of LCD panels of glasses. The second possibility is the use of glasses with changed orientation (down side is upside), no so aesthetic, but functional. The picture with PB 6240 is great! (I not a benq dealer :-) | ||
| Peter Wimmer Rating: N/A |
> Peter, can't change left right wires with > H3D dongle. Is their a solution? To watch videos, yes. Stereoscopic Player can toggle left/right (View->Swap Left/Right, hotkey F7). My H3D controller seems to output a VESA Mini-DIN 3 compatible signal on the IR port, because I've once connected professional wired glasses and they worked. VESA Mini-DIN 3 consists of a ground pin, a 5V power supply pin a TTL-level data pin. Passing the data signal thru a TTL inverter will reverse left/right. | ||
| pheggie Rating: N/A |
Thanks Peter that seems a pretty easy thing to implement for H3D glasses right/left reversal One wire is red presume this is +5V one wire is black assume this is ground the last wire is white I presume this is the one to invert. Can check with a logic probe. If I use a low level schottky ( LS )TTL inverter would that mean I can use the +5V line instead of an external power supply? What's your opinion. Would that inverter have enough power to drive the pair of infrared LED's of the sender. | ||
| pheggie Rating: N/A |
Hi Peter, the H3D manufacturers say no the inverter won't work. The way the glasses knows which eye is active is by the value of the data stream. For example a 0x23 means right eye and 0x33 means left. | ||

A question to hornet I am about to purchase the infocus x3 but from what you are saying I am tempted by the benq pb6240 can you tell me have you tested the x3 as a comparison ? Thanks Mark | ||
| Hornet Rating: N/A |
Answer for marcus: Hi, I have no tested X3,technical parameters are very similar to PB 6240,(res,freq.range of vert.sync, DLP chip,color segment wheel speed,optics ) only light output ANSI is lower (1700 X3 v.s. 2700 ANSI PB 6240). For active stereo is good the light output reserve - the shutterglasses reduces light input in the eye. I not a Benq dealer, only I have Benq in my home and I very satisfied (i have before my purchase the possibility of test of benq). Not so good is lamp life time 2000/3000 h Benq, and lamp garancy 500h or 6 months, lamps are rel.expensive. Benq is wery good for homemade montage of wide angle adapter lens (the picture is with this 20% greather from the same distance). Purchase of projector for 3d is complicated process. | ||

Hi all, Now as you can tell from this post i'm not the most technically minded individual out there. LOL However i did buy an infocus 4805 a couple of months back, and somehow managed to set it up. LOL Wow, i never thought i would ever see anything like it in my living room!!Amazing! Anyway, back to the 3d stuff LOL I was watching one of those colour code 3d films on it and i must say i was pretty impressed with the 3d effect. Now after finding this site through numerous links and having a look at that list Pete posted way back in October am i right in thinking that LCD shutter glasses like the edimensional thingies will actually work with it? You know just the glasses, control box, dvd player and projector? Or even using a PC for that matter? Has anyone tried the infocus 4805? You know guys i might just give it a go and see what happens. I'll still be able to use them with my good old TV, but my god, if it actually works i'll be lost for words!!!!!!! Dave | ||

I have a ScreenPlay 4805 and some old Eye3D shutter glasses. I haven't used the glasses in a long time because I don't have any CRT monitors any more. I tried them on my LCD monitor, and of course it didn't work due to polarization issues. Anyway, I have a Shuttle XPC, so I carried it out to the living room and plugged it into the pj, along with the glasses. By the way, the pj comes with a VGA to DVI cable. Before hooking it up I made sure to get the stereo 3D driver from NVidia, but I had to "downgrade" my Forceware drivers to 78.01. Well, it worked! It only goes up to 75Hz (37.5 per eye), but the 3D effect is quite good. From about 15 feet away, it looked like the NVidia logo was floating right in the center of my living room! Of course, this is not a perfect solution. Eventual headache or fatigue is likely with the flicker. And as expected, brightness is reduced considerably. Make sure you're not running in "low power" mode. | ||

I have a Infocus 5700 I have tried to use it for page flipped 3D images using a NVIDIA G Force VGA card in the computer and E-Diamensional shutter glasses. I set the computer for 85 refresh rate (the 5700 rated at 85) and tested first on my monitor, all ok, but the Infocas shows only one image, then after a few seconds the second image moves up the screen very slowly to cover the first one. Does anyone know the answer, perhaps there is something I have to set up in the projector menu? or maybe the 5700 will not work with page flipped. Any info will be very welcome. | ||

Your paper mentions developing a "custom LCS glasses driver" to compensate for the time offset of the different DLP projectors tested. Does this mean that "off the shelf" shutter glasses hardware and software will not work well with these projectors? | ||
| Andrew Woods (Andrew_woods) New member Username: Andrew_woods Post Number: 4 Registered: 4-2006 Rating: N/A |
Our original purpose of developing the "custom LCS glasses driver" was to allow us to do a wide range of things that you can't do with a regular LCS glasses driver. Firstly we can delay the switching on of the glasses by an adjustable amount, and secondly we can adjust the duty cycle of the glasses (i.e. adjust the switch off time). We can also trigger the glasses from a range of different video types. During the testing of most of the DLP projectors we measured the time offset between the vertical sync pulse and the time at which the projector output light for that field/frame. We did this since it is a potential source for ghosting/crosstalk. We were rewarded for checking this parameter because we found a huge variation between projectors. Of the 85Hz stereo capable projectors, the range was only 0.3ms to 0.96ms (milli-seconds). This may sound small but one frame at 85Hz is only 11.8ms long. 0.96ms therefore corresponds to ~8% of one 85Hz frame. So, if your glasses switch at the 0ms point (the trailing edge of the vertical sync pulse) you could be experiencing ~8% ghosting/crosstalk if you had a projector with a 0.96ms time offset. But I don't know the time offset of your glasses. And we didn't test a wide range of LCS glasses drivers for this property. Of the projectors that we tested that were 60Hz stereo capable, the situation was sometimes MUCH WORSE. We found at least one projector that had a time offset of 8.3ms. This corresponds to ~50% of one 60Hz frame period (16.7ms). This is HUGE! and would completely destroy the stereo effect unless that switching of the glasses was delayed by a corresponding amount. So, in summary, the results of this project DO NOT mean that "off the shelf shutter glasses will not work well with these projectors". It all comes down to what is the time offset of the glasses driver and what is the time offest of the projector that you're using. If the two time offsets are pretty much the same, ghosting/crosstalk won't be caused by bad timing. But if there is a significant different between the two time offsets, ghosting/crosstalk would be present (unnecessarily). Cheers, Andrew. | ||

Andrew, thank you very much for the article! This is an important contribution to the 3D community. Let me add the following to the projector list: Make: Optoma Model: EP716R Resolution: SVGA 85Hz operation: yes Sync delay: 0.5msec | ||

I just wanted to add the following to the projector list: Make: NEC Model: LT180 Resolution: 1024 X 768 85Hz operation: yes Sync delay: 1 frame delay stereo is reversed. This projector is delivering perfect stereo, at least to my eyes at 640 X 480 @ 60HZ up to 1024 X 768 @ 85HZ with no color issues,no loss of sync, and no image cropping. I have watched several 3d films and played a few games on it both for enjoyment and in the last couple of days I reviewed both media critically to see if I could see any of the color issues or any ghosting and I can't see any. Actually there is a DepthQ projector on Ebay for $2500 and I was trying to talk myself into getting it, I just couldn't think of any way the 3d could be better than on my NEC. Keep in mind this is new to me and I am far from a trained eye in these matters, I just thought I would throw this up in case anyone was looking for a good projector for 3d, these are discontinued by NEC so they can be had for around $800.

There is one strong reason why the DepthQ performs far better than any 85 Hz projector, at least for movies: Pageflipped playback of PAL content requires a refresh rate of 100 Hz so that each left/right frame is shown twice. Else, playback is not smooth. For NTSC, 120 Hz are required. Actually, the problems with 85 Hz projection are not obvious when playing 3D-DVDs because most discs are encoded in NTSC format and use an ugly pulldown to convert 24 fps to 30 fps, which causes jerky playback anyway. But if you have ever played a PAL 3D-DVD (e.g. the PAL edition of Haunted Castle) or your own content recorded with two DV/HDV cameras, you'll be able to see the difference. | ||

I have got the Benq PB8230 UXGA, 2500 lumens projector. Ive only got stereo working in the following way: ED Wireless glasses, 1280x1024, 60 hz, general timing formula (NVidia 7600gt). For which I am happy to play for hours with no headaches or eyestrain. When I try this at any other resolution, the 3d image drifts in and out of sync every few seconds. If I try higher refresh rates such as 1024x768 at 84hz, the glasses are totally out of sync with both the frames and the colorwheel, looks very horribly jerky, I assume its because its a 6 segment color wheel and therefore not evenly divisible by 2 at 84 hz. Is that right? The PB 6230 worked well at 85hz I read, would have thought the 8230 would be at least as good... the difference is the color wheel right? I havent tried page flipping because the jerkyness is not even but 1/3 or 2/3 out of phase, bleugh. Oh well. at least it works at 60 hz, which is completely fine, I only see some flickering if I look for it. | ||

Hi, use PB 6240 (2 pcs :-) in 1024x768 85 (84 Hz) problemless with e-dimensional shutterglasses, use the ED activator (ed.exe) for activation of glasses (heve 6600 GT and 77.77 drivers).ED activator can by problematic with new drivers for 7600 GT. With ED activator the sporadic desyncr.are in my setup no present.I think the resolution must by used 1024x768 - this is native res of this projector! And is necessary adjusting of V-sync (disabling), and AA (low framrates). These problems are in movie projection or software-games? Is this with stereoplayer? | ||

How about the Mitsubishi HC5000 1080 projector? Will it work with pageflipped 3d? It says: h-sync: 15-100kHz v-sync: 50-120Hz dot clock: 170MHz http://www.aboutprojectors.com/Mitsubishi-HC5000-projector.html | ||
| Peter iak (Hornet) Member Username: Hornet Post Number: 60 Registered: 4-2006 Rating: N/A |
Hi, this is LCD projector, the V-sync 120 Hz is only highest accepted freqency, the real refresh freqency is max cca 60 Hz, for pageflipped stereo is this very low - picture had flicker. In this time only DLP projectors are compatible with pageflipped active stereo. | ||
| Geir Bakke (Andemat) New member Username: Andemat Post Number: 2 Registered: 1-2007 Rating: N/A |
How do you know lcd is max 60hz? Maybe this one have a new type of lcd. Or is 60hz a physical limitation that lcd will never exceed? | ||
| Peter iak (Hornet) Intermediate Member Username: Hornet Post Number: 61 Registered: 4-2006 Rating: N/A |
I think yes. have no infos about "new" LCD projectors. For home cinema 60 Hz (NTSC or 50Hz PAL) is LCD enough refresh. Have tested 2 LCD projectors, all have no more than 62 hz. Sorry. DLP projectors are no so problematic, only types with big HDpanels are no tested for pageflipping at higher refresh.(This is too problem of signal processing speed and bandwidth of DLP chip and electronic of projector. Generally, manufacturers of consumer projectors are no stimulated and interested in higher refresh technology. In 10 years this were changed (after shock after 3d movie Avatar (J.Cameron cca 2009) and building of home HD 3D cinemas.) | ||

Hey Peter, The problems with the PB 8230 are with the nvidia test application, stereoplayer and games. Tonight I will try the setup like you have (77.77 + 6600GT + ED.exe), previously I could not get stereo to work properly at all with a 6600GT on the projector and using latest Nvidia drivers, but I wasnt using ed.exe. I never used the ED Activator because it locked up the pc too much and wasnt necessary to play games on the CRT in 3d at all. Whats the point of using ED.exe? I thought it was unnecessary if you used the NVidia stereo3d driver? Thanks for your help. | ||
| Joe Warwick (Jwarwick) New member Username: Jwarwick Post Number: 3 Registered: 1-2007 Rating: N/A |
Ah I see the refresh rate problem: 8230: H-Sync Range: 15.9 - 60.0kHz V-Sync Range: 20 - 100Hz 6240: H-Sync Range: 20.0 - 88.0kHz V-Sync Range: 20 - 85Hz Dang, Ill have to trade up to the 8240 if I want higher refresh. | ||
| Peter iak (Hornet) Intermediate Member Username: Hornet Post Number: 62 Registered: 4-2006 Rating: N/A |
Hi, V sync range of 8230 is good, I think the same as 6240 (100 hz is only in MAC mode, had 6240 too in manual 20-100 hz) Important is use of 1024x768 res, ED activator remove the sporadic random "flashes" when the FPS drops, with ED is simple the R/L reversing, is no necessary hardware reversing of glasses. I have with my setup practically no problems, works well, of course. I use setup with 2 6240 and Matrox Dual head2Go adapter (super wide projection for games and simulators). | ||

I presented a detailed technical paper on this topic at the 2007 Stereoscopic Displays and Applications conference in San Jose, California last month. www.stereoscopic.org/2007 The paper describes a survey of 45 consumer DLP projectors to establish whether they were compatible with time-sequential 3D - in various video modes and connection methods. The paper also discusses the reasons that some projectors are not time-sequential 3D compatible e.g. deinterlacing problems, synchronisation problems, etc. The paper contains a compatibility listing for the 45 DLP projectors tested - including listing 15 projectors that were 85Hz time-sequential 3D compatible. This paper is more detailed than the paper previously referenced on this thread that was presented in August in South Korea. The full reference for the paper is: Woods, A.J., Rourke, T., (2007) "The compatibility of consumer DLP projectors with time-sequential stereoscopic 3D visualisation", presented at Stereoscopic Displays and Applications XVIII, published in Stereoscopic Displays and Virtual Reality Systems XIV, Proceedings of SPIE Vol. 6490, San Jose, California, 29-31 January 2007.

Hi I use 85 hz refresh and this is good, have tested 86 Hz (custom refresh in drivers) ant this +-works (PJ displayed 86 Hz). I think 85 Hz is acurate refresh for this PJ. Use this problemless with Matrox DualHead2Go adapter (2x1024x768 = 2048x768 resolution and second PJ) and this is bombastic setup for flight simulation (85Hz 3D stereo compatible), | ||

The Benq MP720P is bloody brillient. Very bright image. Set to 1024 at 85Hz. Have it set on economy mode and still bright. Helps to be in the cellar though (no light noise). Simlpy tried the 'beta' 93.71 stereo drivers and the nvidia test image and some JPS's. No cross talk, no ghosting. A little flicker on the white spaces but not bothersome. Excellent image quality. Have not delved any further but can imagine playing with the projector controls will deliver even better results. Com'on STALKER!!! A happy Unclebob. | ||

| Andrew Woods (Andrew_woods) New member Username: Andrew_woods Post Number: 11 Registered: 4-2006 Rating: N/A |
Thomas Schäfer asked whether the MP720P would work with Field-Sequential 3D DVDs. I haven't tested the MP720P myself, however, I can offer the following. Across the 45 DLP projectors that we tested, only 4 would correctly display in 3D the composite or SVideo signal played from a field-sequential 3D DVD. This is because most DLP projectors use a deinterlacing algorithm which mixes alternate fields (not good for 3D). My strong suspicion is that the MP720P will fit in this category. There is however usually one way around this problem, and therefore make the projector be able to display the field-sequential 3D DVD directly. Play the 3D DVD on a progressive playback DVD player (such as the Panasonic DVDS1), connect the player and projector using component cables/connection, and whalla the projector will display the 3D signal correctly. But note: - not all progressive DVD players will convert the interlaced video signal to progressive in a friendly way. We've only found a few Panasonic DVD players that will do it e.g. the Panasonic DVDS1. - this method will flicker at 60Hz (30Hz per eye) - Computer playback of the 3D DVD will allow operation at up to 85Hz (less flicker on suitable projectors) but motion artefacts may be present. More info here on my new 3D projector list: http://www.3d.curtin.edu.au/3dmovies/projectors.html BTW: readers of this forum may be interested in an extensive article just published on stereoscopic gaming using DLP projectors: http://www.tomshardware.com/2007/04/10/wall_sized_3d_displays/index.html | ||

The new Mitsubishi PK20 pocket projector works perfectly at 85Hz. Stable picture, no color distortions.

Not usable for viewing (unfortunately). | ||
| Andrew Woods (Andrew_woods) New member Username: Andrew_woods Post Number: 19 Registered: 4-2006 Rating: N/A |
Thanks Yitzhak. I've added this projector to my web list of 3D compatible projectors: http://www.3d.curtin.edu.au/3dmovies/projectors.html By any chance do you know what the colour cycle speed of this projector is? (Although it is an LED projector (and hence it doesn't use a colour wheel), it still uses the colour sequential technique to display a full colour image from a single DMD panel.) | ||
| yitzhak weissman (Itsikw) New member Username: Itsikw Post Number: 5 Registered: 9-2006 Rating: N/A |
Sorry, I did not have yet time to perform any measurements and tests on this projector. Therefore, I do not know what is the color cycle time, but I can clearly see the rainbow. I saw good 3D in pageflipping mode at 85Hz, so the delay cannot be too large. | ||

Using two projectors provides NO advantage for anaglyph (red/blue) 3D. However, using two projectors (plus silver screen, polarisers, and polarised 3D glasses) you could do polarised 3D projection! What 3D video modes did you try with your NEC VT670's? Most of the NEC projectors we have tried have been able to do VGA 60Hz 3D (see: http://www.3d.curtin.edu.au/3dmovies/projectors.html ) - did you try that mode? | ||

Hi Anonymous, i have a question. You write, that your infocus x1a works on 60Hz, 75Hz... How you can change it? I bougt this projector too, but i have problems to see a good 3d Picture. There are no problems with colors but most time i see ghost pictures. (i mean the right and the left pictures are not really seperated. Only sometimes. I think i have to change the frequenz. But how i can do. my DVD recorder is playing interlaced an my shutter glases and the sync box are also special for dlp projectors. It is better to play from a computer where a can change the frequenz? And when i take the computer, can i also take the momitor cable or only the composite or s-Video cabel? Thanks and sorry for the bad english. Oliver | ||
| Andrew Woods (Andrew_woods) Junior Member Username: Andrew_woods Post Number: 21 Registered: 4-2006 Rating: N/A |
Hello Oliver, The Infocus X1A will not accept field-sequential 3D Video successfully via the composite or SVideo ports. It mixes the left and right eye views and causes ghosting. To get field-sequential 3D DVDs to work on this projector it is necessary to either: 1. Play the 3D DVD using a Panasonic Progressive DVD player such as this one http://www.amazon.com/exec/obidos/ASIN/B000EOH1MM/3dmovies-20 and connect to the projector using the component connection (and the DVD player switched to progressive mode). Note that NOT all progressive DVD players are 3D compatible. or 2. play back from a PC using software such as Stereoscopic Player www.3dtv.at connected via the VGA connectors. The frequency of DVD cannot be changed just with a DVD player. It is fixed at either 60Hz or 50Hz - depending upon the particular DVD you have. The vertical video frequency of the PC is set in the control panel for the graphics card. The Infocus X1A projector cannot change the video display frequency. It just displays what it receives. More information is available on my website: www.3dmovielist.com/projectors.html Cheers, Andrew. | ||

I just bought a sharp XR10X with ED glasses and it works, as stated on Andrew's list  , at 1024*768 @ 85hz. The only mishap on my road to home VR was that no game would page-flip...until I gathered information on this forum and on MTBS... I had to disconnect one of the cores of my X2 4600 to get nvidia drivers to work (msconfig > boot.ini > advanced > NUMPROC=1 / just deselect NUMPROC to get the second core back -don't panic, you can't select 2 to go back, but deselecting will do the trick!)Once single-proced, most games worked great!

Yuri asked if the Benq 830/831 could work in stereo at 85 Hz? I'm not aware of this projector being tested for 3D compatibility. Judging only by the specifications, the chances are not good.... 1. The native resolution of the SP830/831 is 1280x768. In our testing, only projectors with a native resolution of 1024x768 (or lower) were capable of 85Hz stereo. Higher resolution projectors could only do 60Hz stereo, if they could do it. 2. Of the 9 BenQ projectors that I have testing records for, only 44% could do time-sequential 3D. Details here: www.3dmovielist.com/projectors.html Therefore, my estimate is that there's a 0% chance that this projector will do 85Hz stereo, and a 44% chance that this projector will do 60Hz stereo. Clear as mud? ;-) If you do get to test one of these units, please let us know the results. | ||

So setting an sxga+ (native 1400x1050) projector to a 1024 x 768 setting would still fail at 85+? If this is true I may just wait a while before buying a projector.. 1024x768 just isn't acceptable for me for certain apllications.

Steve Mace asked: > So setting an sxga+ (native 1400x1050) projector to a 1024 x 768 setting would still fail at 85+? Ordinarily, if the projector won't display time-sequential 3D in its native resolution, it also won't work at a lower resolution. There are some "professional" SXGA+ projectors that can do 120Hz stereo. One example is the Christie Mirage S+3K http://www.christiedigital.com/AMEN/Products/MirageS3K.htm This projector can do 115Hz stereo at its native SXGA+ resolution, and 120Hz stereo at SXGA resolution. We used a projector similar to this at the SD&A 2007 conference. www.stereoscopic.org/2007 This is the only projector that I've seen that can do a higher stereo refresh rate at a lower input resolution. I certainly haven't seen this capability on a "consumer" projector. (and thanks to Peter for the error correction. I'll fix it shortly). Cheers, Andrew. | ||

Firstly, I'm not sure I correctly understand the questions, but here goes... > Are performed tests of new DLP full HD > projectors for the max possible refresh? I don't have any test results for 3D compatibility of consumer grade DLP full-HD projectors. However, I suspect that the maximum 3D compatible refresh rate will be 60Hz. Christie have released a new 120Hz 3D compatible full-HD projector - the Matrix HD4. It is fairly unique in that it will display 120Hz 3D from a 60Hz source - it internally increases the display frequency from 60Hz input to 120Hz display.

RGBHV is electrically the same as VGA - it is just that RGBHV uses 5 separate BNC connectors and VGA uses a 15-pin High-Density D connector. A cable such as this one converts between VGA and RGBHV: http://www.altronics.com.au/index.asp?area=item&id=P1769 > Have idea: Blu Ray player + HDfury HDMI to > VGA Adapter Cable + VGA pass through dongle > +shutterglasses + RGBHV input of full HD DLP > PJ = HD "pseudostereo". Firstly, using Blu-Ray as a source will limit the display frequency to 60Hz. Secondly, I am not aware of any field-sequential 3D Blu-Ray or HD-DVD discs available yet. Thirdly, playing a 2D Blu-Ray disc in this way will not allow it to be seen in 3D. Fourthly, "pseudo-stereo" means something else. It means that correct 3D images are being displayed on screen, but you're viewing with the wrong eye polarity (i.e. left image to right eye, and vice versa, instead of left image to left eye). > Have tested combination of DVD player vith > VGA output+pass through VGA dongle +shuttergl > + DLP XGA PJ +Planet Earth DVD = amazing > home cinema! Viewing a 2D DVD in this way will NOT produce correct 3D viewing. Apologies if I've misunderstood the questions. (Message edited by Andrew_Woods on November 12, 2007) | ||

Hi thx for answer. I use DVD player, shutterglasses with VGA pass thr.dongle . It is not ideal = it is no true 3D - of course. Only the pulfrich phenomena and brain antialiasing with only minimally flicker (of course) resulted in more more better perfomance than simple 2D. The new movies are all with dynamic camera shifts and cca 70% of time is 3D efect little or more present. For my this was shock, becose the result is very good (non comparable to normal regular 3D stereo) only subj.very very good. The advantage - simple, cheap, and no special 3D DVD are needed. BBC Planet Eart in this -awesome. | ||

QUESTION ABOUT BENQ AND GOLDEN RATIO COLOR WHEEL ================================================ Hi! I've read this post, and also Andrew's and Tegan's study. I was thinking of buying a BenQ MP721 projector, though it's hard to find now. MP721c, cheaper, is very easy to find, althoug. As far as I have read, this proyector has a "Golden Ratio Color Wheel", with 5 segments. 1. I understood from this thread, all MPs have 5 segments wheel? Can you confirm MP720 and MP721 do also have this wheel? 2. I have read Hornet and Unclebob said bias for MP720 was not a problem, so should I expect the same results we get with 720 or 721 if I buy 721c? 3. Do you know if there is any significant difference between MP721 and MP721c apart from lumens? It is strange MP721 is no longer sold, while MP721c is easyly found, and cheaper, but 300 lumens less bright. Thanx in advance! Regards! | ||

SHARP XR-10X? Hi Thanx Hornet, yeah! it's too slow. Up to now, I was able to try just the two models I commented before :-( What about Sharp XR-10X owners? Erbipj? Janosz? You say "good stereo" and "no color problems" but... it means "you can notice slight color difference between eyes and your brain's white balance compensates it when using both eyes"? or you mean "there is no color difference at all"? What about ghosting, as for Andrew's and Tegan's paper, there may theoretically be about 2% ghosting due to tie offset at 85 Hz? Thanx in advance. | ||

The Casio XJ-360 is 85Hz 3D compatible at it's native resolution of 1024x768. I expect this would also mean that it will run 85Hz 3D at 800x600 but we didn't test this.

All runs absolutely fine - test application, usual games and all at 3072 * 768 85hz. I have an XFX 8800 ultra extreme here too which cost a fortune and was a little PO'd when I had to downgrade to the 7900 gtx to get the 3d working!

Hi Hornet, Pics will be up soon, I actually borrowed 2 of the projectors which were returned this evening but I've purchased the same 2 which will be delivered next week. Gonna suspend 3 homemade hi-gain screens in a surround configuration (similar to my lcd monitors on TH2G) and have a shelf behind the sofa with the projectors on. I've invested a lot of time and money in the rig as a whole so want to get some decent pics to see if they can be published. Watch this space, is taking a long time to set up as you can prob imagine but will be worth the effort now I've proved it all works I have Condor but not tried it yet, will let you know how I get on! Got _very_ slight ghosting but tbh they are very good projectors for this purpose - do you have any tips on how this could be reduced? (other than knocking down the contrast and up the brightness), I'm guessing there is not a lot that can be done about it | ||

Hey Stant - I'm going to try the MP771 as it looks perfect for this application and would make my triple beamer rig sooo much better! Have you had any feedback about this, do you know anyone who is stocking it yet? (still havent been able to locate one). | ||
| Peter iak (Hornet) Advanced Member Username: Hornet Post Number: 89 Registered: 4-2006 Rating: N/A |
This is good type - the wide field projection is ideal. Have searched - main problem is the higher price (have seen 1700 USD :-(). From 3d stereo point of view, hope is as other XGA Benq PJ good. 3x771, Matrox Triple head, e-dim glasses and Trackir = ideal 3D stereo sim and gaming setup. | ||
| Chris Jarram (Chrisjarram) New member Username: Chrisjarram Post Number: 4 Registered: 11-2007 Rating: N/A |
Yep, its not cheap but sadly might be the only realistic way to get the best setup - would basically result in 3 * 80" displays which can be sat right in front of though which would def be ideal. Problem is they arent due to ship for another couple of weeks and I'm sure they'd be quite a lot cheaper a year or so down the road I'd def be pretty broke if going for this option and dont think my girlfriend would be happy! I've also now added Buttkicker gamer and a MS sidewinder FF 2 usb which are on order - if anyone has any other suggestions on what can make the whole thing more immersive (without going for a motion platform) I'd be very grateful to hear! btw anyone know if anywhere is stocking the Belkin n52te yet? | ||

What a coincidence, I actually had an ivibe delivered from Craig this very day which I am going to test out in about an hour! Its primarily going to be used for rFactor and GPR2, its the best device on the market for its money - I'm going to dissasemble it and mount the tactile transducers in a Sparco race seat which will be sat in a Frex simconmotion. A buttkicker device will then be used to proide additional tactile feedback through the Logitech G25 FFB wheel and pedals - can't wait! Received my 3D-20 IR emmitter today also (www.3dflightsim.com), absolutely fantastic bit of kit - very, very well made, excellent customer service from Alan and flawless results, you can wonder around the room as you please and the glasses dont miss a beat. SO much better than the POS dongle you get with the eDimensional's. Pictures will follow soon. | ||

Has anyone had any success using a 1400x1050 res. projector? I am currently looking at the Dell 5100mp and the Optoma EP910. they both state a 120hz refresh, but I was hoping someone had given it a try. We are trying to set up a 3 wall immersive enviroment and I am trying to do it with out having to use 2 projectors per screen, because of the difficulty in lining up the images. Also, as a side note, I will hopefully be testing a Benq721c next week. It is rated as 1024x768 and 85hz. Some people have talked about this unit previously, but I don't think anyone has tried it.

G'day, I'm really keen to get on board with a DLP like every 1 else. so I found a few that weren't on Andrew Woods list that I was wondering if any 1 had experiences with them with page flipped 3D.... Firstly a few questions. Does it matter if its 4x3 aspect ratio by default or 16x9. Cause some are 4x3 but can also do 16x9, and some are just 16x9 and i guess can do 4x3 with black borders....? Whats the best for 3D Stereo? well the first DLP is a Toshiba_DPD-TDP-T100U http://www.projectorcentral.com/Toshiba_DPD-TDP-T100U.htm it actually says it can do H-Sync Range: 15.0 - 120.0kHz V-Sync Range: 50 - 150Hz Display: Type: 1.4 cm DLP (1) Color Wheel Segs: ** Color Wheel Speed: ** Native: 1024x768 Pixels Maximum: 1600x1200 Pixels Aspect Ratio: 4:3 (XGA) that comes to my other question.... are the 1.8cm DLP colour wheel much better than the 1.4cm like the Toshiba 1? and heres the other DLP that i wanted to c if any 1 had working. http://www.projectorcentral.com/BenQ-SP830.htm http://www.projectorcentral.com/NEC-LT180.htm http://www.projectorcentral.com/InFocus-LP70.htm thats all for now, But I think I will wait for Nvidia's Release of the new STEREO drivers and go from there.

Hi Shono, I wouldnt bother with the LT-180 or LP70, its not really worth using anything less than around 2500 lumens due to the reduced brightness (which is essentially halved) when using shutter glasses. I have not used the SP830, but I'm having my first BenQ MP771 delivered tommorow and will post my results | ||

r k, Cheers for heads up. I just notices that someone in this thread said that the NEC DOES WORK. QUOTE I just wanted to add the following to the projector list: Make: NEC Model: LT180 Resolution: 1024 X 768 85Hz operation: yes Sync delay: 1 frame delay stereo is reversed. This projector is delivering perfect stereo, at least to my eyes at 640 X 480 @ 60HZ up to 1024 X 768 @ 85HZ with no color issues,no loss of sync, and no image cropping. I have watched several 3d films and played a few games on it both for enjoyment and in the last couple of days I reviewed both media critically to see if I could see any of the color issues or any ghosting and I can't see any. Actually there is a DepthQ projector on Ebay for $2500 and I was trying to talk myself into getting it, I just couldn't think of any way the 3d could be better than on my NEC. Keep in mind this is new to me and I am far from a trained eye in these matters, I just thought I would throw this up in case anyone was looking for a good projector for 3d, these are discontinued by NEC so they can be had for around $800. David But just wondering wat this means... Sync delay: 1 frame delay stereo is reversed ? Is that wat Andrew Woods was talking about in his tests with the delay from the colour wheel....cant member now. Anyway, if I was to purchase a replacement lamp for this NEC, it would set me back $650- AU. Thats to much i think, way cheaper in the US but cant ship to Australia..... Anyways, Cheers again.

http://www.stereo3d.com/cgi-bin/discus/show.cgi?tpc=3177&post=23122#POST23122 Andrew (Woods) - fantastic article, many thanks for your research. I think the burning question is, out of any of the 85hz DLP's you tested, did ANY of them not suffer the colour problem (as the article states 'most', not 'all')? Just curious... | ||
| Chris Jarram (Chrisjarram) New member Username: Chrisjarram Post Number: 10 Registered: 11-2007 Rating: N/A |
"But just wondering wat this means... Sync delay: 1 frame delay stereo is reversed ? ". No, this is not related to the colour wheel, that is a separate issue - it means the page flipping is the wrong way round, i.e. to see stereo that is correct (not parralax inverted) you'd need to wear the glasses upside down, or alternatively (short of hacking away at the glasses) buy one of Alan's IR immiters or parralax correctors to fix this:- http://www.3dflightsim.com | ||
| Chris Jarram (Chrisjarram) New member Username: Chrisjarram Post Number: 11 Registered: 11-2007 Rating: N/A |
p.s. I was lucky enough to purchase the first 3d-20 of the line from www.3dflightsim.com and this unit is AWESOME. Highly recommended for the cost, you guys all need to buy one. It fills a large room with IR, and I have 6 pairs of eDimensional wireless glasses for large audience viewing. (NB it also fixes the fram delay problem indicated above). Fingers crossed combined with the MP771 this will be a perfect solution - more to follow. | ||

| Chris F (Chrisdfw) New member Username: Chrisdfw Post Number: 11 Registered: 4-2006 Rating: N/A |
Yes, it does. The more times it spins per frame the more likely it will hit each color enough that it won't matter. The slower wheel might hit the red wheel 2 times in one eye and once in the other while the fast wheel doing 2 reds in one eye and 3 in the other makes it much less noticeable. | ||

Hi, Chrisjarram, Can you select pageflipping mode in Nvidia stereo menu after connect the projector? I had problem when I connect with latest model of Toshiba DLP projector, Windows recognise it with pop up sound like a USB connector and then automatically disable pageflipping mode. So I removed #12 pin from D-SUB 15 pin connector it seems MONITOR ID for Windows. Windows can not find the model name but just a CRT monitor. It works with pageflipping mode after remove #12 pin. I am looking forward to hear good news. | ||

| Peter iak (Hornet) Advanced Member Username: Hornet Post Number: 96 Registered: 4-2006 Rating: N/A |
I think first step is creating of new resolution and refreshrate (1024x768, 85 Hz this is native resolution of this PJ) and refresh is max.possible value for this PJ. (creating in normal drivers).When you using LCD monitor refresh is normally only 60 Hz adjusted). For tests is ideal old CRT. Using of other higher resolutions above native is possible - only max.refresh is lower (75,or 60 hz). I think this is your problem... | ||

Hi, Apologies if this is a repeat, but I tried posting in what I now realise is an old discussion. I'm London based and keen to buy a DLP projector which can do good quality 85Hz or better stereo - I already have everything else I need, edimensional wireless glasses, decent PC with nvidia card, - but am having great difficulty finding any of the posted list of tested DLP projectors still available in the UK. Does anyone have any advice for current models which are known to work? I'm thinking of the Optoma EP 727 or EP 728 which appear to be near replacements for the EP719, but I can't find anywhere where I can try before I buy. | ||

Just a bit of info for people.. I made an enquiry to Christie to see what kind of cash their professional 3D projectors run at (for comparrison, so anyone looking at a consumer projector stating SXGA+ res at 120hz can see it is not likely this will support stereo as well as you'd think!). The response (which is pretty much what I expected) I got is the SXGA+ Christies (starting at 2k lumen moving to 4k lumen) currently run from 43,995 to 69,995 usd, and the HD ones 47,995 to 79,995 usd. The lenses (not included) range from 5,000 to 5500 usd. So nice and affordable then. Think I'll stick with my MP720p | ||

hi, this weekend i tested with a infocus X3... and the effect is stunning!!! i really like it. unfortunately the beamer is not mine... i own a Sanyo PLV-Z4 (LCD) beamer... which i really like except it's 3D incompatibility... i did not try it yet... but i guess i won't have success with a LCD beamer... Now i'm thinking of replacing it with an other beamer capable of 3D! It should be wide-screen... (1280x720 /768) and not to noisy... and of course with HDMI (not for 3D, but for my PS3) i dont want to downgrade in terms of quality compared to my PLV-Z4... is there a chance to find something like this? or are there any Full-HD Projectors capable of 3D??? Thanks alot for your help! regards Michael | ||

We found several 1280x720/768 projectors that are 60Hz time-sequential 3D compatible. The standouts are probably: Mitsubishi HC1100, MItsubishi HC3000, and Optoma HD72i. But none of the 1280x720/768 projectors that we tested were 85Hz 3D compatible - only XGA (1024x768) (and lower resolution) projectors would do this. There is an extensive list of time-sequential 3D compatible projectors here: www.3dmovielist.com/projectors.html Please note that some of the projectors that we tested were not 3D compatible at all so be careful. | ||

thank you andrew. i know this list of compatible projectors... but i guess this list has not been updated recently... most of those projectors cannot be bought new anymore.. if i look at technical-specifications of a new dlp-projector... is there a way to find out if the projector is 3D capable? i.e. "time-sequential" or special color-wheel? i dont want to buy a new projector and test 3d afterwards... and i cannot take my whole 3d-equipment to the stores to test it there and i don't want to buy an old projector... thanks alot | ||

Yes, it did work, but only in 60hrz, and only with some NVidia cards - others had trouble synching (I had image drift). I think the issues is DVI-VGA-DVI (the cards with vga-outs fared perfectly well). I think soon edimentional will be coming out with a DVI dongle, so things will improve.

For movies is 60 Hz flickering, but better than 2D, I use my old Benq PB 6240 (85 Hz capable) with my DVD player with VGA output and homemade "pass through VGA dongle" and e-dimensional glasses - "pseudostereo setup" (no PC is needed) and this works on 60 Hz, is no so bad, the flicker is only when bright scenes are present. I think it is possible use of Blue ray player , then corventing HDMI to VGA (on market is one HDMi to VGA adapter)(synchronising with glasses) and use of projector with VGA input. Problem is - some HD projectors are no VGA full compatible. Think are only 3 possibilities - older XGA DLP projector, or 60Hz, or waiting. Hope samsung and misubishi build 3D compatible projectors, the TVs are too DLP machines. | ||

Well I have done that, I have some leads but not so much. If you stumble over a link, please post it. I actually came over a second DLP proj, du you have any ideas over the fun stuff you can do with two projs and 3d glasses. I have 7950gt card (two dvi). And yeah BTW I have a laptop with a Geforce go 7600 card, can I output it to an external screen and get 3D. Would be so nice than I can go around and check what projectors work in stereo.

Hello guys, if you want to know.... I went to a store and tested the Optoma HD65. They had a very good price on it but it seems that it can only do 60hz in 3d. It´s native resolution is 1280x720 but I didn´t get any stero there. Overall the proj was so slow accepting a new "signal" so only that was tiresome(when I did the nvidia 3d testpage). The good thing was it wasn´t that much flicker which I would have thought and there were no one frame delay problem. But I guess this one isn´t going to make anyone want to buy it. I also tested another, I guess rather old proj now. It´s called Gehe compact 007(1024x768), it loses its sync so it´s goiing in and out of 3d so no luck there either. So if you had the time to read this maybe you could say something about this: It seams that there are not so many projectors out there that can handle 3d if they are widescreen?! The optoma can only handle 60hz, I guess you don´t need much higher than that since you´re gonna use it for film anyway. So I guess the projectors that can handle stereo good is those ordinary 4:3(dlp ofcourse), or what do you guys think? Over and out. | ||

Hi Guys, Right, got my XR-10X's delivered today but there is some nasty red ghosting which makes them pretty much unusable in my eyes. I'm sure this MUST be fixable as this projector is top rated for 3D - does anyone have any suggestions? I'm running at 1024*768,85hz - tried both ED wired and wireless glasses - same result. Thanks for the help!! | ||

Hello Chris, I've two of those Sharp XR-10X and I use them in stereo 3D either individually, or together using a DualHead2Go, with absolutely NO ghost effect. Your problem could be due to your TH2Go. Perhaps you could try your VPs individually first. By the way, my DH2Go is an analog one. Which kind is your TH2Go? Analog or digital? Anyway I'm sure it's NOT a problem with the VPs, but rather with your TH2Go, or 3D glasses or the batteries of your glasses (try with new ones). | ||

Hornet - Hows the simulator coming together? Just a question re: DualHead2Go (maybe anyone else could help with this also?) as I've had a few issues with my TH2G which are causing a bit of grief. The main one is sometimes my projectors (one or more) won't synch to the incoming VGA signal from the TH2G at higher frequencies (e.g. 85hz).. I can select 'input scan' on the projector again several times, and eventually it will, but when it doesnt it basically looks like the image is correct though there is a black bar down the left (almost as if the frame timing offset is off or something). Do you ever have this problem with the DH2G? As far as I'm concerned it may just be with the TH2G but Im considering maybe downgrading to DH2G for certain stuff. The other question is, have you ever used stereoscopic Player (or a similar IMAX-dvd playback software) across 2 screens with the DH2G (changing the aspect ratio)? I've tried it here across 3 but all I get is a black screen :-/ Thanks if you can help! Chris | ||

I have a Optoma Projector now that doesn't stay in sync with the stereo scopic edimmensional glasses I have. Therefore, I would like to get a projector that I can use with 3D. I had read that the BenQ MP720P worked good for 3D Stereo, but I noticed the Benq MP770 also had all the same specs and case dimensions except that it was quite a bit brighter(3200 Lumens). Just wondering if anyone had tried this. I also noticed that they have a 771 short through projector with similar specs, but it is a different case and maybe enough different that it won't work, but if it did it would be great for smaller rooms. If anyone has any suggestions or ideas on these, let me know. Thanks, Jeff | ||
| Chris Jarram (Chrisjarram) Junior Member Username: Chrisjarram Post Number: 26 Registered: 11-2007 Rating: N/A |
Hi Jeff. MP771 short throw doesnt work at all (well, it does but 60hz only) - I've tested it. I own the MP720P and it is fantastic, no problems at all (apart from the usual slight colour balance difference) - amazing stereo. The MP721 is its replacement, which is easier to find now and has also been successfully tested. Dont know about the MP770, but if it has similar specs to the 771 (apart from the short throw, obviously), then I'd avoid it. In my experience, the best ones to pick from are the Sharp XR-10X (NB NOT the XR-10XL) (2000 lumens but less colour problems than the BenQ's), the BenQ MP721 (2500 lumens) and the BenQ pb6240 (2700 Lumens). I'd warn you against buying projectors based on speculation / similar specs to those already tested etc - I've done this before and found a lot of them dont work. Hope this helps, Chris | ||

Hi, I have won a bid on ebay for a Sharp XR-10X. I received it today and what a surprise...it is an XR-10XL!!!! Holly shit!(scuse me but i simply can't deal with that In spite of the deception, I tried it. And I have to say that at 75hz, it perfectly works. I tried it on my tapestry, so the brightness wasn't good but I had no color deformation and no ghosting. A perfect stereo. My only disapointment is that the shutter glasses (edimensional) often desynchronise on two or three images very often. Have anyone got the same problem with the shutters?

Hi, I followed the Links to the List of Compatible 3D Projectors and I purchased a Projector but there was a typo or error of some sort with the Link to Amazon. I think AmaZon just linked to the ClosesT Match so If you click thru the Compatible list Check to make sure it is the Correct one ;) The Projector I wanted to get was the Sharp XR-10 "X" but the One I bought was a Sharp XR-10 "L" Model. I checked Projector Central and the Only listed a XL version and the X. I wanted to know will this L Model still work in 3D?? PLEASE I need ana Answer ASAP If this Will work it said it was 85hz. I am using the ED Wireless 3D Glasses. it is sort of a Mini Virtual Flight Simulator.

Desynchronisation - use ED activator.exe (from homepage of e-dimensional) This had solved my problem with desynchronisation when the graph.card is loaded.

Hi, I have no prbleme at 75hz such color deformation or ghosting with the XR10XL. I have not tried yet the 85hz mod. So Jerry: Yes, the stereo works with the Sharp XR140XL at 75hz. My only problem is the flicking. but I really think it is cause by the shutters glasses. More test later. You guys, have you got flicking at 85hz with edimensionnal? | ||
| Chris Jarram (Chrisjarram) Junior Member Username: Chrisjarram Post Number: 29 Registered: 11-2007 Rating: N/A |
when you say flicking, if you mean flicker it is very minimal (almost zero) at 85hz - can only really be seen in very bright areas (e.g. pure white) but typically you can watch at 85hz for hours with no eye fatigue. Me personally, I can't bare to look at anything below this (75hz included) for any period of time. Daniel, can you tell me if you have tried any games such as 'rFactor' or the like with the XR10XL? While the NVidia test app appears to be ok, there seems to be other colour anomolies not described in this forum. Certain areas of the image are fuzzy, like there is a colour 'noise', and in rFactor particularly this makes it look like someone has splilt ink all over the track. I have NO such anomoly with my BenQ's, but myself (including the other user below) have the same problem with the XR-10XL. It may not have been apparent to you yet, but could you test this and let us know if you're seeing the same thing? Please see the following thread (with photos of what I mean):- http://www.mtbs3d.com/phpBB/viewtopic.php?p=6229&sid=84994e32fd3220e134fc590810036c3c | ||

Re Hi guys! So... finally... I am happy! I have just finished to try yhe 85hz mode. It is almost perfect for me! No color anomalies and no ghosting (exept on very bright parts like windows in the night but I don't know why) but it is not disturbing. I have tested on a virtual world I have made. It is almost in the night but you have a church within great contrast and a large range of color. So I don't test a commercial video game, but my 3D engine is Vertice Nova ( www.vertice.fr ), it is a directX based engine like almost game today. So it sis a good test plateform. Chris: I don't test rFactor, but I know this thread. This artefact make me think that is due to the mix game engine refreshrate. I wonder it it is a real 85hz. We could think that the refreshrate of the engine is in conflict with the refresh rates of windows (even if those one is set to 85hz). Result: you have got a real 85hz at the output but the color subsequence sould be asynchrone; making a blue dominante. I am not sure of what I have said so tell me if I am totally wrong.

Hi Daniel, Will test your scene but I am seeing the rFactor anomoly in many different games / scenes. As of today I've corrected the red ghosting (thanks to Alan at www.3dflightsim.com), but have not been able to fix this color problrm. As I said in a previous post though there is NO such anomoly with my BenQ - and it is def all running in sync. I have no idea what is causing this but there is some sort of colour 'noise' in the image. I am not sure what you mean about 'mixed' refresh rates - you are only putting out a single 85hz refresh at a time, controlled by the foreground application. Thanks anyway, Chris | ||

Could really do with a picture without and with glasses to ensure the colour problem isnt present. This problem is something I've never seen with DLPs in stereo3D before but I've got the same issue with 3 XL's here so I'm still a little sceptical these work properly - for instance, the problem is barely noticable in the NVidia test app, but then you get games using certain colours and its terrible Thanks if you can help It would be nice if I could at least keep these units! | ||

Chris, I think, they are added some color wheel segments in XL (white?) - it is possible -desynchronising in 3D more than 3 color segments is problematic. The new PJs are with "golden ratio" color wheel - better collors, only no full 3D compatible. | ||

Hi Daniel, There are colour problems with most things I have seen with the XL, as Hornet indicated I think this is as it has a different colour wheel to the XR-10X. There is simply a lot of 'noise'. Interesting though, I have a few other games I'll try this out with to see if I can help out any more. Thanks, Chris | ||

Re, Here it is! I have managed to get your color anomalies! In fact, at the first run, I have directly changed the color parameters to compensate the 'blue effect' due to the glasses. Here is some pics: 85hz Stereo ON Without Glasses http://imagik.fr/view-rl/38006 85hz Stereo ON With GLasses Color's projector parameters at Standart http://imagik.fr/view-rl/38007 85hz Stereo ON With GLasses Color's projector parameters personnalized http://imagik.fr/view-rl/38008 As you see I exactly the same effect as you: a ink dash! Now look at the third image with my parameters. The effect has decreased! Contrast: 25 Lightness: 25 Red: 0 Blue: 0 Clr Temp: 6500k Increase white: 2 I don't how but I know what is it. It is a gamut clipping.ou can have the same effect in photoshop playing with curves. The color wheel is for something in that deal for sure. It is interesting to see how the effect decreases when you plays with the color parameter. I wonder ( no time to test for today ) if playing with the color parameters in Nvidia driver or playing with parameters in the vp menu give the same effect...

Hi Daniel, Thanks for the pics The color gamut clipping theory is a good one, it certainly explains the hard edges I get across gradient-shaded areas. However, I'm still curious as to why this is not visible without the glasses. In terms of the driver I'm pretty sure it isnt anything to do with that as my Benq projectors work fine with the same setup - it just seems to be the sharps 10XL's that are dogged with this problem :-s. If you manage to find a solution to this you will have a friend forever! I've nearly given up on the 10XL's but if this can be fixed I'd certainly keep them Thanks again for all your effort! Chris | ||
| Daniel Neveux (Vikti) New member Username: Vikti Post Number: 14 Registered: 11-2007 Rating: N/A |
Today the best solution I have found is playing with the parameters of the projector. For the fact that the effect is visible only with glasses I have one theory. The XR 10 XL has a gammut management for the R V B different from the XR 10 X. To get the full gammut of each image it need three colour wheel rotations. For exemple. If you have an image with horizontal lines of greys the XR 10 XL will cut it in three passes. 1 for te very dark ang light greys, 1 for the intermediate greys, and a last one for the finest greys. Lets the images talks...: http://imagik.fr/view-rl/38199 For this example I cut an image in three parts of the histogram: extreme, average and finest repsectively with a light value of 0 to 84, 85 to 169 and 170 to 255. Then I put each image into a layer with an opacity of 33%. The result is the original image which demonstrate that the manipulation is possible. Now if each layer is displayed with a colour wheel rotation and if one segment of this color wheel is obstruct by the shutter it could cause a clipped histogram. I tried several situation and I think that famous segment could be the red one! See the images bellow: The orginal through the ED glasses OFF. http://imagik.fr/view-rl/38189 The same with with the ED glasses ON http://imagik.fr/view-rl/38195 Now, my simulation into Photoshop: the final image: http://imagik.fr/view-rl/38193 I am not very far from the reality!! Here the third part of the histogram send by the projector. http://imagik.fr/view-rl/38196 This image is the extreme colours parts of the image with a red composant clipped at 33%.

I have got my Simulator All setup and I am NOT sure if I am Running at 85HZ I know to setup in the computer but is there something in the projector I must setup or does it choose what I have set on the Computer?? I have the Shapr XR10X-L Proj. I am also using the ED 3D Wireless glasses. | ||
| Daniel Neveux (Vikti) New member Username: Vikti Post Number: 16 Registered: 11-2007 Rating: N/A |
To run at 85hz with the XR10X-L you have to "force" the 85hz in the Nvidia driver. | ||

I have just finished my test for the Acer PD725P : doesn't work at all! You have the rainbow effect and the stereo is totally out of order. In addition I took photos of its brightness ( 3500 lms ) compared to the 2000 lms of the XR10XL. Here are the pics: The PD725P http://imagik.fr/view/39366 The XR10XL without my custom settings. http://imagik.fr/view/39371 The XR10XL with my custom settings to decrease the gamma clipping. http://imagik.fr/view/39368 I first calibrated my camera for the PD725P 1/10 F5 to take exactly what i was seeing. I think the difference of brightness between the two projectors is not very signifiant! What do you think of that? | ||

Hey David, Thanks for your reasearch! I think it makes total sense what you have said about the gamut clipping, and you are right that the effect does change slightly when altering the color temp of the projector. After this, I have also noticed that the anomoly is present _very slightly_ with my benQ's also, which drop down to 1.5x cw speed at 85hz. Anyway, I've tested the Sharp xr10-xl's into the ground and decided the problem is just so damn awful no amount of playing with the parameters is going to eliminate this enough... when I put them next to my BenQ's the benq's are superior in output (and also look about twice as bright, even though they are only 500 lumens more!?). Its a shame because the output of the sharps really is 'sharp', but I'd recommend strongly against the xr-10xl model - its no good for stereo. Thanks again however, keep up the good work! | ||

I think I found a sort of a workaround for the ink Blotches we get with the Sharp XR10X-L. I had reinstalled the drivers on a unrelated issue and it set the monitor to "Default Monitor". I had cehcked and the setting it was Before was a "Plug and Play Monitor" when it was set to the Default Monitor I was getting Blotches of green sort of like the ink blotch as mentioned in the above posts, but when I set the Monitor type to Plug and Play monitor the Blotches went away and I had a Normal looking game?? So If you have the Sharp XR-10X-L I would try setting the Monitor Type to something elseperhaps "Plug and Play Monitor" as that seems to work fine for me. maybe that is the trick for the InkBlotch Problem and this Projector??

Hi Jerry.. Depends, can you confirm that when you did this the refresh rate was still definately operating at 85hz? Assuming what Daniel has said re: the gamut clipping is correct, this would likely be due to the fact the colour wheel speed changes at 85hz so each eye is seeing a different number of colour wheel passes than it would at, say, 60hz. Daniel, what do you think - have you tried Jerry's suggestion? | ||
| Jerry Lafrance (Nephilim) New member Username: Nephilim Post Number: 14 Registered: 3-2008 Rating: N/A |
Hi Chris, How can I check to see if it is running at 85HZ?? It appears to be as it doesn't look like it is running at 60hz.. I am also Downloading rFactor and GTR2 to test for the Ink Blotch. I will try it 1st with the Plug & Play Monitor then switch to the Default Monitor in Monitor Types and see if I get the Ink Blotch. EDIT: I had emailed Sharp Tech support about them making a driver for this Projector. So can whoever else has this Projector do the same maybe we will get a driver??

It could be running at 60,72,75 or 85 typically.. usually the projector will tell you when the signal is switched to, if not you can try and force it in the Nvidia driver and / or using a tool such as RefreshForce/RefreshLock. It seems to me Daniels investigation does answer the question as to why the incorrect gradient shading (i.e. ink blotch) in certain colours appears - and it would seem to be a hardware limitation but again you really need to test it with something like rFactor/GTR2 as it is very noticable in these games. Let me know how you get on! | ||

As an aside.. I need to be able to run my projectors at 640*480 for a couple of apps (dont ask why!) so I need to use the trick to force them to be identified as CRTS. Can anyone advise me how to do this? I know numerous techniques such as disabling pins or attaching resistors can be done to spoof monitor id's, but I'm guessing someone here will have done this to force a projector to be detected as a generic CRT. Is there any easy way? Thanks for any help! | ||
| Jerry Lafrance (Nephilim) New member Username: Nephilim Post Number: 15 Registered: 3-2008 Rating: N/A |
I installed Refresh lock and locked it in at 85hz. When I run GTR2 and rFactor it does NOT state what hz it is running at just the Rez and input1. I did NOT see the ink Blotch in either game no matter what monitor type I selected so perhaps I just had a fluke occurance but I see NO Ink Blotch in any game?? Perhaps it is a Harware limitation??

hmm.. this is very interesting. I'll have to take a look when I get home. I have sold 2 of these now but have one I might keep for a second rig if it still works (I've got 3*BENQ mp720/1's for my main rig now instead). Will be a bit of a bugger if they do work after all, but one thing I did notice is the BENQ's were significantly brighter used in stereo (and I can use them with DVI and my TH2G digital in mono) so not all is lost :-\ | ||

> The other question is, have you ever used stereoscopic Player (or a similar IMAX-dvd playback software) across 2 screens with the DH2G (changing the aspect ratio)? I've tried it here across 3 but all I get is a black screen :-/ I've tested the Matrox TripleHead2Go with the NVIDIA Stereo Driver and Stereoscopic Player today. And it worked! The trick is to select View->Full Screen Monitor->Monitor 1 + 2 in the Stereoscopic Player. This is a bit confusing, because there is one destop and three monitors, nevertheless the player detects two monitors. The reason is that the player assumes a span mode configuration in the grpahics driver (which never consists of three monitors) and divides the destop by two. The NVIDIA stereo driver only works on the whole destop, so it is necessary to select 'Monitor 1 + 2' in the player so that the player uses the entire desktop. In the stereo driver, I selected 3072 x 768 and 75 Hz and pressed the 'set for all resolutions' button. Btw, the medical test image and the image viewer in the stereo driver did not work. They switched back to the 4:3 resolution and unloaded the Matrox driver (a reboot was necessary to make the Matrox driver work again). This was my test configuration (I didn't had three identical displays available, but this shouldn't matter; pageplipping was clearly visible).

At 1024x768 it has a 140hz refresh rate or that is what they claimed?? I am thinking of getting this Projector for my 3D Home Theater ?? So any news on the Sharp PG-M20X and using it for 3D?? | ||
| Chris Jarram (Chrisjarram) Member Username: Chrisjarram Post Number: 43 Registered: 11-2007 Rating: N/A |
Unlikely. 140hz (actually its probably 120) will be the supported refresh rate but the native will likely be much lower. They say there is a double data rate chip though which is interesting, but the reality is if you wanted 'real' 120hz at 1024*768 or above you probably need something like a Christie, which start at about $44,000. | ||

Hi, I just found out How much I didn't know about the nVidia Stereo Control Panel. I Found out I was NOT getting the Correct Refresh rate to work. When I thought I was running at 85 hz it was actullay Only running @ 75HZ that is why I did NOT see the Anomolies. But Now that I can change to 85 Hz (I Wish it would show when launching a Game to know for sure) I see the Color Anomolies. Besides there being Ink Blotches in the Simulator I get these Psychadelic Color Anomolies as well, Really Wierd. The Sharp XR10-XL will goto 85Hz but when you do you get the Anomolies with the 3D Glasses, even if you do NOT enable Stereo but have the Glasses On. The Only Fix is there is NONE, except to Run at 75Hz or Buy an Different Projector (The BenQ MP 720-21's are getting High Praise). Which I think is OK not to bad running @ 75Hz but I guess I am just used to running at that Refresh rate ;) I also Emailed Sharp Tech Support Some time ago they do NOT offer Tech Support if you Run the Projector in 3D (Message edited by Nephilim on July 25, 2008) | ||

Sounds about right - not sure how you mistook 75hz for 85hz tho, I cant even look at 75! Yep the BenQ's are great, but the XR10X (not XL) is better if you can find one. BTW if anyone is interested I have a surplus MP721 in as new condition with case (and v low lamp hours) I was planning on listing on ebay for Ł300ukp + post (just under what I paid for it). Its slightly better than the MP720p, but I have 3 of these which match so the MP721 is the odd one out. | ||

Hi Everyone, I am a newbie here, however not to the topic I am about to buy a DLP...deciding between Benq720p or Shark XR-10X but Shark bulb are shortlife are very expensive (3x more that Benq720p, 721) and at PC lot of very negative comments on bulbs life(not even 1000 hours) . Do you have anyone experience with the Toshiba TPD-T95? It has the Compatible Scanning Frequency Vertical (Hz) 50 - 150Hz(!). But on XGA allows 85Hz only, but is that up to 1600x1200 does 85Hz also. I wonder if this is some advantage regarding 3D - e.g. better image quality if I use 1600x1200, or - crazy idea - is it possible to hack it to raise above 85Hz at XGA?? | ||

Hi Zoltan, There are no consumer DLP projectors capable of displaying ref rate above 85Hz. There is no way that you can modify this. When manufacturer says that the projector is compatible with a certain format, it means that it will show the content, but not necessarily at the same format as the input. In particular, the TPD may be capable of showing signal with ref rate of 150Hz, but the display will be probably 60Hz only. Itsikw | ||

No. The X is ok, it is the XL that has the issues. In fact, the X is widely regarded to be the best projector on the market for 3D due to its 2x colour wheel speed at 85hz (one pass per eye). | ||

Chris I didnt mistake 85 for 75 it is just that I had it set at 75HZ in the Stereo Setup Test Page under Miss "Always Use Stereo Refresh Rate". I had it set for 75 HZ and in the Screen Rez and Refresh rates I had it set to 85. So I thought I was in 85 HZ but It was Overridding it to 75 from the Misc Always Use Stereo Refresh Rate page .. | ||

Hi, Can anyone tell if NEC LT260 would support 3D projection for shutter system? Please let know what should be the settings as I got double flickering image on screen using DVD PLAYER & 3D DVD without the 3d effects. Deepak | ||
| Andrew Woods (Andrew_woods) Junior Member Username: Andrew_woods Post Number: 36 Registered: 4-2006 Rating: N/A |
Unfortunately the 3D compatibility status of the NEC LT260 is unknown. But I think there is a very good chance this model is 3D compatible since several other NEC models have been confirmed to be 3D compatible: www.3dmovielist.com/projectors.html But you can be our tester for the LT260!!! I think your problem is the way that the projector is being driven. Very few projectors will work in 3D when driven via the composite or SVideo connectors. You'll need to try one of two methods: (1) drive the projector via the component video connection (three separate RCA cables) from a suitable DVD player. The component video output of the DVD player must be switched to "progressive output" mode. You'll need to check your DVD manual how to do this - it is an important requirement. Please note that unfortunately the "progressive output" mode of some DVD players is itself not 3D compatible. Here is a list of DVD players that have been confirmed to be progressive component 3D compatible: Australian models: Soniq QPD100B European/Australian models: Panasonic E65, S-33 American models: Panasonic S55, S47, S1; GPX D1816 (via VGA, set to progressive output); Durabrand DVD-1002 (unconfirmed) The Durabrand DVD-1002 looks VERY similar to the Soniq QPD100B so I think it is a very good chance of also being progressive component 3D compatible - but it is unconfirmed at this stage. It's available from Amazon for only US$27: http://www.amazon.com/exec/obidos/ASIN/B000GWD32E/3dmovies-20 (2) drive the projector via the VGA connection from a PC. The PC will need to run suitable 3D software - probably the first one to try is "Stereoscopic Player" from www.3dtv.at Cheers, Andrew. | ||

Jerry, 75 vs 85 hz is immediately different! I for one cannot bare to look at 75hz for any length of time - if everyone accepted 75 as the same difference as 85 the projector compatibility list would grow tremendously... anyway I've sold all my 10xl's now and sticking with the BENQ's which are great. | ||

Hi Andrew, I have SONY DVD PLAYER Model 55NP. It has Progressive button on the panel but I dont see any difference in picture when I press it. I have tried using the Sony DVD Player to play 3D movies and I see shaking double picture. The Shutter glasses shaking isnt too much on the screen what is seen on CRT TV. The image on the screen is shaking and my LCS glasses also but still there's two images on the screen visible. Can it be the fault of the Screen? Is there any test through which I can find out if NEC LT260 is supporting 3D? I would try testing with VGA input today and posts the results here. Let me know if there's any other way to project 3D on the screen.? Deepak | ||

The Sony is likely not progressive component 3D compatible. But you should notice some difference when you change from component interlaced to progressive - The projector should at least blank for a moment while it reaquires the signal. Are you sure you are connecting your DVD player to your projector using the component connection (Y,Pr,Pb - 3 cables). Using a PC is probably the easiest way to test, but you'll need more equipment, including a VGA 3D dongle, and some projectors are component progessive 3D compatible, but not VGA 3D compatible... | ||

As I mentioned, some projectors support 3D component progressive but not 3D VGA. (see my list: www.3dmovielist.com/projectors.html ) There is still a chance your projector in 3D compatible via component progressive connections. You may need to buy a confirmed 3D compatible DVD player to complete this test.

Deepak: Information about Component Video connections is here: http://en.wikipedia.org/wiki/Component_video With DLP projectors, 3D video over the composite/yellow video connection usually doesn't work. It is usually necessary to use the component video connections - and the DVD player must be switched to progressive out. But as I said earlier, the progressive output of some DVD players themselves are not 3D compatible - so it still may not work because of the DVD player. It is likely the Sony isn't 3D compatible so it may be necessary to purchase/borrow a confirmed 3D compatible DVD player. See list above. | ||

> Do you mean that you got no 3D effect at all at other refresh rates? (up to 85Hz) Please be more specific with your information - it will help us understand your problems. Yes other refresh rates did not show any sign of 3d. But at 60Hz, only for a second there is 3D and the it goes out of sync and again it comes back for a second. This goes on and on eye straining. About the Component Video - How do I connect the Y, Pr, Pb to the Projector? The Projecter terminal has S-Video, Video In (Yellow), VGA in.

Oh dear... to access the component video input on the NEC LT260 it looks like you need a special VGA to component patch cable. See "Component Video Cable (ADP-CV1)" on this page: http://www.nec-pj.com/products/g3_lt260.htm Amazon seems to have an equivalent cable for only US$7: http://www.amazon.com/exec/obidos/ASIN/B0012SPNII/3dmovies-20 | ||

Buying from Amazon would take much time as I am from INDIA. Is there any way I can make my own Component Video Cable for the projector? Deepak | ||
| Andrew Woods (Andrew_woods) Member Username: Andrew_woods Post Number: 41 Registered: 4-2006 Rating: N/A |
You will need good basic electronics skills to build your own VGA to component video cable. If you do have those skills, it is possible. I think this is the pinout of a VGA to component video patch cable (but note that this is only suitable for DLP projectors that specifically say they can accept component video via the VGA connector): http://www.tkk.fi/Misc/Electronics/circuits/vga2rgbs.gif Also, ignore the circuitry connected to pins 13 and 14. The easiest way to construct such a cable is to grab a VGA to VGA cable. Chop off one end of the cable (leaving a male 15pin VGA connector with a length of cable). Open up the cut end of the cable to reveal three mini-coax cables - usually coloured red, green and blue. Solder these mini-coax cables to three RCA connectors. (shield to shield, centre wire to centre pin). You'll need to work out which is Y, Pr and Pb. Good Luck! | ||

Hi, The site is not opening. It says "PAGE CANNOT BE DISPLAYED" Can this layout be used for the projector? http://www.engadget.com/2006/09/05/how-to-make-a-component-video-switch/ Deepak | ||
| Andrew Woods (Andrew_woods) Member Username: Andrew_woods Post Number: 42 Registered: 4-2006 Rating: N/A |
Bizarre - the link works fine here... The engadget cable you have provided the link for has the same pinout so it should also work, but I would use RCA connectors rather than RCA audio cables (reduce the non-coax cable length). ON TOPIC WARNING: This latest discussion is about how to get a DLP projector working with 3D. As soon as Deepak can finish his testing and report his results we can get back to the usual details... | ||

Hi Andrew! I have finally made the Component Cable myself. Now the problem is where do I connect the video of 3d sync box? I would use the Pb, Pr, Y from the DVD Player to VGA IN of Projector - Where do I fit the 3D sync box video in? Thanks and waiting... Deepak | ||
| Andrew Woods (Andrew_woods) Member Username: Andrew_woods Post Number: 43 Registered: 4-2006 Rating: N/A |
The 3D Sync box needs to be plugged into the composite (yellow) socket on the DVD player. 3D Sync boxes can't read a progressive video signal so unfortunately it can't be plugged into the Y-component socket. This does however assume that your DVD player still outputs a video signal on the composite output when it is switched into progressive-component mode. I still have my doubts whether your SONY will have this capability - but it is worth a try. Good Luck. | ||
| Deepak (Systeminflow) New member Username: Systeminflow Post Number: 11 Registered: 9-2008 Rating: N/A |
Hi, I have followed your process connecting Composite Video to the 3D sync Box and connecting Component to the Projector. When I press the Progressive button on DVD player the picture while switching, on screen (showing half, half) for a second shows clear 3D but when the projector stabilises the picture to full screen the 3D vanishes!!!! The Sony DVD Player is showing fine 3D on CRT TV using Composite Video OUT. Let me know any other suggestions to test out? Deepak | ||
| Andrew Woods (Andrew_woods) Member Username: Andrew_woods Post Number: 44 Registered: 4-2006 Rating: N/A |
I suspect that your SONY DVD player is not progressive 3D compatible. i.e. the algorithm that the DVD player is using to convert from interlaced to progressive is probably mixing the odd and even fields. Try to get your hands on a Panasonic DVD player or one of these specific models: Australian models: Soniq QPD100B European/Australian models: Panasonic E65, S-33 American models: Panasonic S55, S47, S1; GPX D1816 (via VGA, set to progressive output); Durabrand DVD-1002 (unconfirmed) | ||

Hi all, did you have a lookto the latest generation of 120Hz projectors announced by sanyo and epson? Any idea if they will support real 120Hz signals? I've seen Viewsonic monitor recently accepting 120Hz native (and being used for tereo) and I'm wondering if these new projectors will support the same. Any idea? http://www.electronichouse.com/article/sanyo_adds_120_hz_1080p_projector/C91 http://blogs.zdnet.com/home-theater/?p=105 Related to: http://www.insidehw.com/News/Hardware/ViewSonic-Showcases-120Hz-Display-Technology-at-NVISION-2008.html Franco | ||
| Andrew Woods (Andrew_woods) Member Username: Andrew_woods Post Number: 45 Registered: 4-2006 Rating: N/A |
Regarding 120Hz projectors from Sanyo and Epson and 120Hz displays from Panasonic, Sony, etc. Unless the product specifically mentions 3D (like the Samsung 3D HDTVs and Viewsonic 3D LCD monitor) the simple capability of 120Hz processing will not mean that these displays are capable of Stereoscopic 3D Display. The 120Hz processing that these (non-3D) sets are using is intended for improved 2D motion reproduction and this capability does not directly lend itself to 3D display. Sorry to break the bad news. Deepak: how are you going with your projector? | ||

The best option for a component field-sequential 3D compatible DVD player is probably the SONIQ QPD100B. It is only AUD$38 (~US$28), is small (cheaper to ship), can be made region free**, and can play both NTSC and PAL DVDs. Unfortunately this particular company will only ship the QPD100B within Australia: http://www.digitalhome.com.au/Tvs_And_Home_Theatre/DVD_Blu-Ray_And_PVR/Soniq/QPD100B_DVD_Player/24793 I might be able to help if you're interested in this particular player.

Can someone post a few links to help me get my Infocus X1A projector working correctly with my shutterglasses? I've searched and searched but can't figure this out. I have: WindowsXP GeForce 7600GS with 163.75 & 162.50 drivers edimensional shutterglasses & dongle Stereoscopic Player (set to "Nvidia Stereo Driver") Dell 1907 LCD monitor Infocus X1A No matter whether I set the PJ to 800x600 or 1024x768, 60hz-72hz-85hz . . . doesn't matter. There is NO STEREO. My glasses are set for pageflipping and they flicker, but no 3D. All I see is BOTH left & right images on the PJ, whether windowed or full screen-doesn't matter. I can see the difference in flicker when I change the refresh rate from 60 to 85 (BIG difference) but still, NO 3D. Is there a tutorial posted somewhere that can "walk me thru" the correct setup procedure? I've been at this for 14 HOURS now and am ready to throw the PJ thru the wall LOL! Any help would be appreciated! | ||
| Chris Jarram (Chrisjarram) Member Username: Chrisjarram Post Number: 52 Registered: 11-2007 Rating: N/A |
Mark, assuming the flicker is at a constant rate consistent with the refresh, sounds to me like you have a time offset problem there - as far as I know the only solution is to use a bit of circuitry with a variable resister to delay the DDC square wave coming from your VGA port. | ||
| Jerry Lafrance (Nephilim) Junior Member Username: Nephilim Post Number: 37 Registered: 3-2008 Rating: N/A |
Mark do you have Both the Projector and LCD Monitor Hooked up at the same time foir Dual View?? If so that will make Stereo NOT work unplug the Monitor and have just the Proj. plugged in or try some older Drivers like the 93.71's | ||

| Chris Jarram (Chrisjarram) Member Username: Chrisjarram Post Number: 53 Registered: 11-2007 Rating: N/A |
Mark, Dual view makes no difference as in this mode the monitors, resoltion and refresh rates are configured completely independantly. I have no idea what Jerry has managed to do with his system but I have run 2 systems in all kinds of modes with dual view, and there are zero problems dong this. So long as you have your VGA dongle on the projector output (which I assume you do) that should be all you need. There is no reason whatsoever dual view should affect your stereo output, and as you say your glasses are shuttering without issue. (Message edited by chrisjarram on October 20, 2008) | ||

Thanks for the replies. I STILL cannot figure it out LOL! My monitor and PJ are set to "Dual View" and independently configured... I pulled out my old Panasonic DVD player and hooked it up to the PJ with a VESA/component breakout cable. Low and behold, it works perfectly! Of course, it's only refreshing at 60, but it still looks pretty great! I'll still play around with my PC and Nvidia card to see if I can get it working, as 85 refresh has less flicker with the shutterglasses. | ||
| Jerry Lafrance (Nephilim) Junior Member Username: Nephilim Post Number: 39 Registered: 3-2008 Rating: N/A |
I have tried to get Dual View working and Stereo at the Same time but never managed to get it working. At the Time I hade 2 22" CRT Monitors and used Dual view but when I wanted to game I could Not get Stereo 3D To Enable unless I disabled Dual View. So for kicks just try Disabling Dual View and perhaps try the 93.71 Drivers and Stereo Drivers.. Chris Can you post some Specs like the Vid card you used and the Drivers for Dual View and Srtero to work?? Also was it with CRT Monitors or or Projectors?? | ||

Mark, assuming you are wanting to watch 3D films as you are using stereoscopic player, try installing the ED activator from Edimensional, setting it to page flipping mode and, instead of using nvidia stereo drivers in stereocopic player, use software pageflipping. Make sure you turn off the nvidia stereo drivers in display properties first! Let me know if this works for you. | ||
| Chris Jarram (Chrisjarram) Member Username: Chrisjarram Post Number: 55 Registered: 11-2007 Rating: N/A |
Chris, How would the edimensional dongle be able to differentiate between the Left and Right eyes in this case? I'm guessing The DDC square wave will not be output in this case, and usually the only solution to this is to use a BLC dongle or similar to be able to determine which image is for which eye... | ||
| Chris Cowie (Chrisc007) New member Username: Chrisc007 Post Number: 5 Registered: 11-2007 Rating: N/A |
Hi Chris, it doesn't matter about differentiating left/right when using Stereoscopic player as you can simply toggle between left and right. | ||
| Mark Blodgett (3d_dude) New member Username: 3d_dude Post Number: 4 Registered: 10-2008 Rating: N/A |
Chris, Thanks for the input! I have got 3D games & screensavers working in "correct" 3D with the ED Activator (forgot I had that). I didn't have a problem with "reverse" 3D using the Stereoscopic Player, It was only with 3D games & screensavers. But still, in Sterescopic Player, I'll have to try turning off the "nVidia Stereo Driver" and setting it to "Software Page Flipping" tonight. Perhaps will get better performance? When watching a 3D movie on the PJ, I do notice that the image looks a little "weird" when people/objects start moving around (don't know how to explain it). Kinda like slight, "lagging trails" behind them. This is all new to me and this could just be the way 3D looks with the X1a and player. The major problem I have now is with trying to play 3D DVD-R's with the Stereoscopic Player. If I want to watch a retail DVD, I have to make a copy to DVD-R in order to watch it, as the player won't play copy-protected DVDs. The big drawback is that the Stereoscopic Player won't play ANY of my current 3D DVD-R collection I already have ("House of Wax", "Dial M for Murder", etc). When I try to play them, there's TONS of tiling & freezing all over the place! All of these 3D DVD-R's play fine using NERO ShowTime, DVD Shrink or a regular DVD player. None of these "home made" DVD-R's will play with Windows Media Player either. This limits my 3D viewing to only retail DVD's that I have to buy then copy to DVD-R, and none of the collectible classics I have. Very narrow 3D selection to choose from for $50 LOL! Has anyone else had this problem? Any work around? I'd love to buy the Stereoscopic Player, but not if I can't play any of my classic 3D collection. Thanks! | ||

Hi, I had the same Problem with the StereoScopic Player which I purchased and the Tech guy sent me a fix to Play CopyProtected Disks. Send them an Email and see if they can send you the Fix. I have the Underground DVD's like House of Wax and Dial M for Murder they work Fine for me.. I watched House of Wax and Friday the 13th in 3D already..I just enable the ED Activator and use the nVidia Stereo Drivers.. Works Fine for me ;) | ||

I found Stereoscopic Player to be a picky beast when it comes to getting the right combination of codecs to play ALL your DVD collection. I now have a combination that works. I'll post the combo later (I'm at work at the moment and can't remember off the top of my head). As far as I can remember, both video and audio codecs that I use are freebies! | ||

Hi, for your information, I just tried pageflipping with an Nvidia GF7900GS and an Benq PE5120 projector. This projector was already listed somewhere to be 3d compatible at 60 Hz. I just found out that it also works perfect at 75Hz and 85Hz. At 85 Hz there is only a very slight color difference between left and right picture. The only drawback of this model is the limited resolution of 848x480. BTW: I used old ELSA Revelator glasses with a corresponding VGA dongle which I got for 1 Euro from Ebay. Best regards - Uwe | ||

I sent you such an email on 23rd Oct (13 days ago!) and still no response... hardly handling it 'efficiently'. The license for Stereoscopic player is 59 Euros, which is not cheap. What's going on? | ||
| Peter Wimmer (Peter_wimmer) New member Username: Peter_wimmer Post Number: 19 Registered: 5-2006 Rating: N/A |
Ok, here I am. Sorry for the delays. A few comments on the long response times: As most of you probably know, I'm doing all the work for the Stereoscopic Player besides another job. Thanks to the paying customers, I could already reduce my other job to 30 hours per week, but it is still not possible to give it up entirely and work fulltime on the player instead. I receive an increasing number of emails, much more than I can actually handle. I try to give high priority to registered user. If you are a registered customer and you don't get an answer within a week, please let me know (and begin your email with "I'm a registered user" or something similar). Of course I also appreciate mails of unregistered user, especially suggestions for improvements. As customers usually want to fix all troubles before they order, I have a strong interest to help them as well ;-) DVD playback: For legal reasons, I cannot ship DVD video and audio decoders with the Stereoscopic Player. From a technical point of view, it would be no problem. Windows Vista Home Premium and Ultimate ship with the Microsoft MPEG-2 Video Decoder, which handles most of the DVDs and even supports copy protected disks. For Windows XP users, there is the GPL MPEG Decoder but it doesn't support copy protected disks (at least without the patch). The GPL MPEG Decoder has some issues with non-standard DVDs (e.g. the copies of VHD disks lije ("House of Wax" and "Dial M for Murder") but it works fine for all commercial DVDs. In the File|Settings|Decoder dialog, it is possible to select a different DVD video decoder. I had good results with the Cyberlink Video/SP Decoder but please note that you must click File|Video Decoder Properties after opening the DVD and set the decoder to 'weave' mode, else it performs deinterlacing and destroys the 3D effect. PS: The private player license is 39 Euro, not 59 Euro. The commercial license is 89 Euro. | ||

If anyone is interested I have a Sharp XR-10X (the proper one NOT the xl model) and a BENQ MP721 projector, both for sale. They are both in excellent condition with low lamp hours. I have another XR-10X I am keeping (for a second gaming setup) and 3 x MP720ps for my triple rig so these are surplus to requirements. I am in the UK Looking for 300ukp each, drop me an email if interested - they'll be up on ebay in the next couple of weeks otherwise. The great news is, these should work with the new nVidia 3dVision glasses, which have been tested to work at 85hz@1024x768 with old-school CRTs. | ||
| Andrew Woods (Andrew_woods) Member Username: Andrew_woods Post Number: 47 Registered: 4-2006 Rating: N/A |
Regarding the X1a projector query. No, it won't accept field-sequential 3D video directly. You need to use a special DVD player. BTW: This information is detailed on my website: http://www.3dmovielist.com/projectors.html Check the "Composite and SVideo" column of the "Full 3D Projector Compatibility and Incompatibility List". Only a few projectors have been confirmed to accept field-sequential 3D Video directly (via the composite or SVideo connectors). Fortunately it is relatively cheap and easy to get a "special" DVD player which will allow the X1a and many other DLP projectors to show field-sequential 3D DVDs (albiet with 60Hz flicker). | ||

Hi all, I've been using 85hz DLP projectors exclusively for my 3d solution over the last 2 years, and some of you may have already seen the latest thread for my sterescopic home simulator project which all of this has yielded:- http://www.mtbs3d.com/phpbb/viewtopic.php?f=3&t=2907&hilit=home+simulator There were a bunch of issues to get around to make all this work with the greatest effect, a large one of which was the slight timing differences (and eye reversing etc) which are inherent with using consumer 85hz DLPs (which have different signal propogation times in their electronics). This would result sometimes in significant ghosting and inverse parallax, which could all be resolved with some circuitry to delay this signal. Following this I sat down with a friend who is an electrnoics engineer and he offered to put together a delay controller with me to test - this was completed a few weeks ago and yielded such excellent results he's offered to build these to order for anyone that wants to use 85hz dlp's with shutters. This dongle works with all 3d-capable 85hz dlps I've tested (namely the Infocus X1, Sharp XR10-x, BenQ MP721 and others, the full list can be found at:- http://www.stereo3d.com/cgi-bin/discus/show.cgi?3177/3347). The great thing about it is it has a standard VESA output, meaning it will work with shutter glasses such as the following flawlessly, you just plug this into your vga port then your existing IR emitter straight into it:- * nvidia 3dvision - Plug the output from this into the VESA input in 3dvision glasses to resolve sync issues using these with 85hz DLP projectors (this is a great solution, as there is significant ghosting and eye reversal when using 3dvision without this). * eDimensional (wireless) - replaces the eDim VGA dongle completely, just plug your little IR emitter into it. * Stereographics CrystalEyes (2/3 etc) * ELSA revalator In all the time I've spent using DLP's such as this, this is the product I've been looking for and finally all my glasses technologies (CrystalEyes, eDimensionals and 3dvision) work flawlessly with all my projectors (Infocus X1, Sharp XR10X and BenQ MP720P). Personally I will _NOT_ fork out thousands of dollars for a DEPTHQ with inferior lumens output, and 85hz is extremely comfortable for me, I personally notice no flicker in 99% of scenes and can use it for days on end without any kind of headaches or eyestrain. If anyone would like one of these, I've asked Neil if it was OK to post a link here - they are built to order with a lead time of 2 weeks and the order / pricing info is on the following page:- http://nextstepsolutions.co.uk/home/node/11 Hope this helps, finally I have flawless projected 3d using my GTX280 on 3 screens, hurrah! Any questions please feel free to PM me or contact James at the link above. Happy big-screen 3d'ing! :D Chris | ||

Hi, have tested this piece of hardware (my one is from the first manufactured units) - absolutly no problems, works very good. For my benq PB 6240 is this hardware little luxus - the sychronisation is wery good too without this unit. Next step - testing of new projectors with this unit. | ||

Hi All, Got the chance to test a couple of prjectors today. BenQ MP620p Works excellently upto 85hz Acer x1260 Will not work at all. Toshiba XS1 works at 60hz only. was hoping to buy the BenQ for my own use however the unit had a fault in its driver board but when it did work it was excellent. The Acer and Toshiba I tested are current models. Has anyone else tested any other current models? Jenny | ||

Have Found Another Projector that works but only when setup a certain way. Epson 400W ultra Short Throw. Yes I know this is a 3LCD projector but heres the way it works you have to run the projector in 1024x768 at 60hz (yes 60hz sucks) In this mode all bar approx the bottom 100 lines of pixels stay completely in sync. This setup is obviously no good for gaming but for Movies it's fine as a 16:9 movie is cropped by almost this much anyway. My next project is to get a couple of Pcos LC Shutters (100mm x 100mm) and design a shuttering system for 2 of these projectors. (I know Silver Screen etc but Good Silver Screens are expensive) With an External shuttering system for the two Projectors I should be able to drive the Shutter system at 120hz or more. DIY Depth Q at a greater Resolution, Short Throw and CHEAPER. Jenny | ||

Two of my customers say they are using the PJD6220-3D successfully. The first customer is a university where the projector is used with a Quadro card and the XP operating system. (They are also using my long range IR emitters ). The other customer is using the projector for a home theater. It is driven with the Edimensional PC dongle. | ||

I have owned the Infocus Depth 3D projector (800 x 600 Hz at 120 Hz) for several years and am happy with it EXCEPT for the 800 x 600 resolution, which shows a visible hint of pixelization at a 9-foot throw distance. The DepthQ projector accepts both analog and digital video input, and the digital screen image is notably better. I suspect that overall the Viewsonic image should be better (higher resolution, brighter lumens, later-technology DLP unit) even without digital video input -- but I hesitate to buy a second 3D projector without some assurance that this is true. Has anyone on this forum had a chance to compare the old Infocus DepthQ projector with the Viewsonic PJD6220-3D? Any information on this would be appreciated. | ||
| Chris Jarram (Chrisjarram) Intermediate Member Username: Chrisjarram Post Number: 64 Registered: 11-2007 Rating: N/A |
Don't be fooled by the Viewsonic - it is checkerboard in order to acheive the 120hz refresh. This is a cheeky cheat which gives you half the overall resolution (so ACTUAL res for each frame is only 512 x 384 - lame). There is no cheap amazing 3d unit out there at the moment, full stop. The DepthQ us still the daddy, the depthQ HD being the one to go for if the resolution bothers you. I still use 3 x BENQ MP720p's with TH2G Digital and Nvidia 3D vision (plus a bunch of CrystalEyes 3 glasses) and it gives fantastic results. | ||

Thankfully, I THINK this is wrong. The "wobulated" rear projector TVs used chips with half the number of mirrors and "wobulated" the chip back and forth to achieve the full resolution. For 3D, they used "back" for one eye and "forth" for the other--hence halving the resolution any one eye saw. The view sonic I believe is a full resolution chip, they are just using a checkerboard interlacing pattern to render the full image. The interlacing is presumeably to get around the well known bandwidth limitations of the TI chip set. Again, this is just my understand of Viewsonics vague explnanations, but if you read their explanation carefully, it says they take the left/right frames and separate them into 4 checkerboard interlaced frames to render the full resolution. | ||

> I thought Checker boarding only halved your resolution in one direction, a little like line interleaved 3D. The resolution is neither halfed horizontally nor vertically. It is difficult to say how much resolution you actually loose with the checkerboard format. All you can say is that the number of pixels used for the left and right eye is only 50% of the 2D resolution. | ||
| Andrew Woods (Andrew_woods) Member Username: Andrew_woods Post Number: 48 Registered: 4-2006 Rating: N/A |
I have used the Viewsonic PJD6220-3D (120Hz 3D DLP projector) and can confirm that it accepts 120Hz frame sequential 3D video - which provides full XGA resolution per eye. I don't think it also accepted checkerboard 3D as an input format. I also had a DepthQ (800x600) 3D projector setup and, as expected, the biggest difference is the increased resolution of the Viewsonic. Although the DepthQ HD 3D projector (with 1280x720 resolution) is better still. | ||
| Chris Jarram (Chrisjarram) Intermediate Member Username: Chrisjarram Post Number: 65 Registered: 11-2007 Rating: N/A |
Peter is right - it is 50% on each, when I said 'halved' I meant on horizontal and vertical, so in fact the number of pixels are only a quarter. Andrew, the viewsonic is checkerboard in 3d mode. yes you get a full page of pixels per eye, but only a quarter of the pixels are actually active if running in 'true' 120hz mode. The result is, although the brain may perceive this as a full page, it will be a marginally fainter image and is not 'true' 1024x768 res per eye. It doesnt accept checkerboard as an input format, it divides the images up internally to be able to get the data through the TI chipset quickly enough. Put simply, while technically you can acheive a full resolution per eye, if you do you are only actually seeing 30 stereoscopic frames per second, not the 60 you get with the DepthQ. Otherwise, to acheive 'true' 120hz stereo 3D (60hz per eye) you'd need to have each eye as an interlaced image. For comparisson - 85hz I can acheive with my BenQ MP720p is flicker-free in a dark room, and provides a 'true' 42.5 fps per eye at 1024x768, compared to the lesser 30 fps per eye with the Viewsonic. I guess it is a matter of personal preference (do you really need 120hz?), but the bottom line is the ViewSonic is not what it at first appears to be and therefore should not be considered technically equivalent to the DepthQs. | ||

Hi all, Question about the ViewSonic DLP projectors. I have an old Asus 3D card that has wired 3D glasses sync built-in with VGA out. I bought a ViewSonic PJD6211 under the assumption that it can do 120Hz XGA. When I run the projector seemingly at any resolution or refresh rate, I get massive flicker with the glasses on, just looking at the desktop or whatnot. It's as if they are not in sync correctly. Same works fine on a CRT monitor. Any tips? | ||
| Jason Meltzer (Jasonm1) New member Username: Jasonm1 Post Number: 2 Registered: 9-2009 Rating: N/A |
Jumped the gun on that post. I installed the drivers for the projector, which seem to have solved the general flickering problem. It sure seems to take a general 120Hz VGA signal from a computer. Is that not the case? | ||
| Chris Jarram (Chrisjarram) Intermediate Member Username: Chrisjarram Post Number: 66 Registered: 11-2007 Rating: N/A |
It may take a 120hz signal, but will only be displaying 60 of those frames per second (30 per eye), so I'm guessing it just buffers 2 frames and drops the next 2 each time - might be wrong though. | ||

After some time, reading the board with a degree of envy, I've decided to (maybe) get a projector for 3D. I don't suppose anyone has any experience of the MP range of Compaq/IPaq/HP projectors? Like the MP1400, MP1600, etc. I did note that (I think it was RageDemon) stated that he had/has a MP2810 which had worked for PageFlipping. Also a few of the MP3*** series has been detailed in some of the compatibility lists. But I really wanted a super portable one so the MP series seems to fit the bill. Any ideas with the MP1*** series?? Thanks | ||

A slew of new 120Hz 3D DLP Projectors have now been released. Six from BenQ, one from Mitsubishi, and four from Viewsonic. You may wish to consider using one of these new models rather than a projector that can only do 85Hz 3D. I've listed the new models here: http://www.3dmovielist.com/projectors.html | ||
| Geir Řyvind Vćlidalo (Goev) New member Username: Goev Post Number: 2 Registered: 9-2009 Rating: N/A |
Are you sure those are all 120Hz? The Benq MP626 seems to be 85Hz, so does the MP777. | ||
| Andrew Woods (Andrew_woods) Member Username: Andrew_woods Post Number: 50 Registered: 4-2006 Rating: N/A |
All of these models are listed as "DLP 3D READY" on the BenQ website. e.g. MP626: http://www.benq.com/products/Projector/?product=1575 MP777: http://www.benq.com/products/Projector/?product=1569 I can only presume "DLP 3D READY" from a professional manufacturer means 120Hz Frame-Sequential 3D compatible. | ||
| Chris Cowie (Chrisc007) New member Username: Chrisc007 Post Number: 12 Registered: 11-2007 Rating: N/A |
I think you need to update your list, most of those listed as 120Hz are, in fact, only 85Hz - Benq are quoting 85Hz as having mastered 3D from a single projector!!! | ||
| Elber Junior (Erbipjr) New member Username: Erbipjr Post Number: 2 Registered: 7-2007 Rating: N/A |
From Benq website, all mentioned 3D projector are 85/86 hz only. | ||
| Andrew Woods (Andrew_woods) Member Username: Andrew_woods Post Number: 51 Registered: 4-2006 Rating: N/A |
Indeed the specs on these projectors list a max vertical frequency of 86Hz. However, BenQ showed the MP772ST at Infocomm'09 running 3D at 120Hz. I wonder if 2D mode is limited to 86Hz, but 3D mode accepts 120Hz. If anyone has any further info, please share! ;-) | ||

I have a ViewSonic PJD6211. It really seems to display a 120Hz VGA signal from my computer. At least, the response is identical to my CRT. I'm using a really old Asus 3D card and Asus 3D glasses, so that card is certainly playing no tricks with the signal. Now, it has a "3D Stereo mode" which may enable the checkerboard masking needed by certain applications. You can turn it off, however, which is how I run it (stereo mode off, 120Hz vsync). | ||
| Andrew Woods (Andrew_woods) Member Username: Andrew_woods Post Number: 52 Registered: 4-2006 Rating: N/A |
Similarly I have tested a Viewsonic PJD6220-3D and can confirm that it also correctly displays frame-sequential 3D at 120Hz. However the firmware did need to be updated to work correctly in 3D mode. I recently redid my tests of the PJD6220-3D to check for any evidence of checkerboarding mentioned by Chrisjarram. There was absolutely no decline in performance to indicate that there is any checkerboarding being used. I can only assume that there has been some confusion with the way the Samsung and Mitsubishi DLP rear-projection HDTVs work, which use a half-resolution (diamond pixel) DMD. The DLP front-projectors don't use a half-resolution (diamond pixel) DMD (they use a full-resolution (square pixel) DMD) and therefore don't need checkerboard. Unfortunately Chrisjarram seems to be off-net at the moment and I haven't been able to see if he has any further info on this. Jasonm1 wrote: "You can turn it [3D Stereo mode] off, however, which is how I run it (stereo mode off, 120Hz vsync)." Are you saying that the PJD6211 still works with frame-sequential 120Hz 3D (using shutter glasses) when the "3D Stereo mode" is turned to "off" on the projector? With the PJD6220, when "3D Stereo mode" is turned "off", the projector will still display an image from a 120Hz source but it can't be viewed in 3D - the projector reverts to its native 60Hz update (resampling 120Hz down to 60Hz therefore no 3D). Jasonm1 wrote: "it has a '3D Stereo mode' which may enable the checkerboard masking" I don't believe checkerboard is used with these projectors. Referring to the PJD6211 manual <http://www.viewsonic.com/assets/045/12143.pdf> the only mention of "3D Sync" mode says "On: 120Hz detection, Off: Disable 120Hz". This is consistent with 3D mode being frame-sequential 120Hz 3D - not checkerboard. Incidentally, tests of the PJD6220-3D indicated that it has a 4 segment colour-wheel (red,green,blue,white). In 3D mode, the white segment appeared to turn off which reduced the 3D mode brightness considerably compared to 2D mode. ProjectorCentral suggests that the PJD6211 uses an Red,Green,Blue colour-wheel (i.e. no white segment). Do you notice a brightness drop when you switch the PJD6211 into 3D mode? | ||

I own a Viewsonic PJD6220-3D. I have only tested for one day, but up to now I am very dissapointed with it. In my first tests I did not install any software or driver, and I have discovered, at least my unit, has zero tolerance over 120Hz, so, when sending 120,39Hz it was out of sync, so I had to tune the card settings to go always under 120Hz. Sometimes it didn´t synchronize even at 85Hz (???) and sometimes it lost sync and never synced again even at 60Hz, so I had to turn it off and on again. When everything seemed to work (half the times), I tried with stereo pictures and videos ad 120Hz. I got what I expected, perfect no flickering pictures. So I tried games and got very dissapointed again. Picture was completely different for each eye. There was always a perfect picture in one eye (sometimes left, sometimes right), but the other one was a parody of the picture, it seemed almost a solarized picture, with colour bleeding (like Sharp XR-10X at 85Hz), and a really low dynamic margin in contrast (as If there were crazy gamma and/or contrast settings which makes it unacceptable for me). I imagine its related with wheel sync, but have no idea about what happens. In this post, there´s another guy who also speaks about difference between eyes. He says it only happens with some games (that is consistent with colors being perfect in 3D movies and pictures). He also mentions lumens loosing at 120 Hz, though I haven´t experimented them Andrew. I thought of returning it, but as I live in Spain and have to pay for shipping and it´ll be painfull to get my custom taxes returned, I decided to keep it and further investigate, or sell it as a 2D projector, perfect for 3D photo and movies, but unacceptable for games. I have also notice some blue ghosting, but no one talks about ghosting with this projector. This is a first impression, I have had it for some week in its box. But now, reading Andrew´s comments, I think whenever I have time, I will install the driver and uodate the firmware. Do you think there´s a problem with my unit, it is a poor design or it just needs firmware upgrading and driver installation? Regards! P.S: Where is the firmware update? can´t find id in viewsonic site, (Message edited by echeva on October 16, 2009) | ||

Regarding 120Hz 3D on the new BenQ "3D Ready" projectors, the manual for the BenQ MP670 (available here: <ftp://80.252.92.142/projector/manuals/mp670/mp670_en.pdf> ) says the following on page 34: > Playing 3D function > 1.

Note that 120Hz 3D is specifically mentioned here. However, I have just heard from a colleague who has tested the BenQ MP670 that he was unable to get the advertised 120Hz frame-sequential 3D mode to work on this model. So it seems BenQ have some major 3D problems... | ||

I am not aware of the Toshiba ET10 being tested for 3D compatibility. We tested two Toshiba DLP projectors in 2006 and both were 60Hz and 85Hz 3D compatible, so I think the changes of your Toshiba being 3D compatible are good (but no guarantees). The only way to be sure is for you to test it - sorry! | ||

I don't think the "VIRTUAL FX 3D CONVERTER" will work - the "3D STARTER KIT" may be better. Also, the projector needs to be fed with either a progressive component video signal or a VGA signal - not composite or SVideo. You will need a DVD player which is component progressive 3D compatible. e.g. Try to get your hands on a Panasonic DVD player or one of these specific models: Australian models: Soniq QPD100B European/Australian models: Panasonic E65, S-33 American models: Panasonic S55, S47, S1; GPX D1816 (via VGA, set to progressive output); Durabrand DVD-1002 (unconfirmed) But note that this will only give you 60Hz 3D. I think you would be better off using a PC, Stereoscopic Player and one of these shutter glasses kits: http://www.razor3d.de/3d_pc.asp | ||

hey Stephan, for more info from people using current DLP projector setups with shutter glasses head over to www.mtbs3d.com then go to the forums. I also currently have a 3d compatible Infocus x3 DLP pj that works with some cheap x3d shutter glasses using my windows computer with an older prior 8000's nvidia graphics card. If your going with the pc route make sure you got all the info first before spending money on the glasses, may be better getting the Nvidia 3d vision glasses then can use newer video cards, some people have it working using dlp pj's at 85hz. but first things first, even before buyin glasses you should test the 3d compatibility to see if theres even a double 3d image displayed on the screen. hope that helps ya.

In response to the testing of the BenQ PE7700, I can confirm that this does support 3D. I tested it using the Razor3D system, DVD player attached to 3D hardware via Composite and DVD attached to Projector via HDMI (make sure upscaling is disabled). Does not work if connected to projector via composite. And also it does have VGA input (D-SUB15 to BNC adapter cable required) but I have not tested 3D via VGA yet. | ||

I have a problem regarding Active Stereo 3D Projection. The 3D Software outputs in 3D frame sequential(60 Hz each for left and right eye, alternatively) format. Graphics Card, Nvidia QuadroFX 5800, has 2 DVI outputs and stereo projector is Active Stereo Projection Design F10AS3D, that takes 2 identical DVI graphics outputs as inputs and projects active stereo 3d image by synching/switching with emitter and Active Stereo Eye wears CrystelEyes 3. What splitter/format converter should be used to convert single frame sequential Gralhics 3D stream to 2 identical Graphics, over 2 DVI-I outputs for Active Stereo 3D projection in such setup? | ||

I think Matrox dual Head adapter (analog for analogue VGA signal on DVI or digital version when digital DVI is used) | ||

I will have the Acer H5360 and 3Dvision in my possession soon, so I'll get back to you guys with some info. The projector set me back only 859 dollars and have 1280X720 with HDMI I think that's a good deal. Jesper | ||

Has anyone here used the DepthQ polarization modulator? I want to use one to present photogrammetry instruction to a college class. I don't want to hand out 36 pairs of active shutter glasses.} | ||

If you want a cost effective but quality 3D presentation for a group, think about colocode3D (http://www.colorcode3d.com/ColorCode_3-D.html). Content has to be encoded in this format, that is offered as service by he company. After that, it can be seen through colorcode glasses. The best part is, content can be seen on any display type,without glasses, you will see mono and with glasses, 3d, without loss of resolution or color associated with passive polarization. No external electronics or synchronization is required. They can encode your frame sequential or any other stereo format into color-code . | ||

The is imagery is georeferenced, and already processed. It cannot be modified as the texture and colour are used in training the users. I just don't want to have my students wearing shutter glasses. Has anyone used the polarization modulator mounted on a 3D page flipping projector? I want to find out about the quality of the image when viewed passively. | ||

I haven't personally used the DepthQ polarization modulator, but have been informed by a technician associated with that company that the modulation process (which converts an "active" page-flipped 3-D image back to a passive one) further reduces the intensity of the light reaching the screen (which has already been reduced by the inital "active" conversion within the projector). Depending upon the brightness capability of your projector, you may need to take steps to compensate for this added loss of intensity to get an acceptable screen image for your audience. | ||

In Response to Ceruleanx, Posted on Saturday, May 29, 2010 - 5:11 pm concerning Benq PE7700: Hi, Can you please tell me which type of Razor3D system you took and at which frequncy it worked? Since Razor appears to finish distribition do you know anything about an alternative shop? | ||

Guys, Does somebody tryed 3d on new dell projectors? Especially Dell M410HD - i can find any reports on it - is it checkboarded? it it full resolution? | ||

Hi, I tested the Infocus X6 and it does work in 3D at 60 Hz in its native resolution (800x600). It doesn't work in 3D at any higher frequency (tested 70, 72, 75 and 85 Hz). | ||
