Could any one tell me if it is possible to watch 3-D VHS/DVD's on a 50MHz PAL TV. I'm after buying a 3-D system (H3D or i-art). Because I get the impression that it has to be 60MHz, because NTSC runs at that. Also do the films flicker alot, there are alot of complaints on the board that the films are of rubbish 3-d quality? Also whats the deal with the i-art web site, I can't contact them to purchase their 3-D TV System Thanks for any help. | ||

NTSC (60Hz refresh rate) 3D videos have less flicker than PAL (50Hz refresh rate) due to the increased refresh rate. But you will notice flicker, a darkened room and low TV contrast setting helps. Your TV and video manuals should say if they can play NTSC videos. Make sure the video player is connected to the TV via a SCART or phono/RCA lead. PAL TVs and VCRs which play NTSC videos usually do so by the Pseudo-PAL also referred to as PAL 60 method. See: http://www.techtronics.com/uk/shop/87-00-video-standards-ntsc-pal.html Have you tried http://www.iart3d.de in Germany or http://www.demensional.com in the USA for your i-a-art glasses? The USA site has much better choice than Germany, I can't understand why I-art in Taiwan and Germany insist on selling a pair of wireless and wired in their Premium package!!! I'd would love a pair of Premium glasses but I'm not prepared to purchase two pairs when all I need is one! Since I live in England I get stung for Import duty, Taxes etc... if I bought from the USA. | ||

Paul, set your DVD player to NTSC output mode (this even works if a PAL-disc or no disc is in the player). If you get a stable image your TV is O.K. unless it's a 100Hz digital set. If NTSC doesn't work over video or s-video connectors try Scart-RGB. There's even a slight chance that the 3D-DVD will play in stereo in PAL-output mode depending on how your player does the transfer. Even if it should work it's not a good solution, since PAL flickers more and it's jerky, since the player has to omit 1/6th of the original frames Christoph | ||

My TV can handle PAL 60MHZ. I checked it with my Hollywood+ DVD MPEG decoder card. It can output PAL, NTSC, and PAL(60MHz). When I changed the option to NTSC the NTSC DVD appeared black and white on my TV, through the SCART connection. But when I selected PAL 60MHz it appeared perfect and in colour. So presumably if I output the NTSC 3-D DVD's in PAL 60Mhz then the 3-D effect should still work???? So my only problem so now if I connect my VCR (which plays NTSC tapes at PAL 60Mhz) to the scart connection of my TV, then the tape should still run at the 60MHz required to reduce the flicker. If this is right then MY PROBLEMS SOLVED right??? | ||

Yes it should work and if you manage to use RGB instead of composite video it should work in true NTSC in color. Christoph | ||

Noce one thanks for all your help. I can now go and purchase a 3-d system and as many 3-D films as I can get hold of 'cos their GREAT!!! What system do you recommend, for all round reliability. Also I think we have a different cabling system to you what exactly is RGB? Again thanks for your help, and keep up having THE definitive site for all things stereoscopic. Paul (Leeds UK) | ||

Here in Europe we have 21-pin Scart connections. The Scart cable carries all 3 formats: composite video, y/c s-video and RGB. Most TV-sets with Scart input accept RGB which provides the best quality and goes around of most of the circuitry of the TV. RGB means red, green, blue and addresses the 3 cathodes in the TV-cathode-ray-tube directly. It's somewhat TV-system independent. You just have to stay within the frequency limits of the set. Basically it's the same as VGA, just with lower frequencies. If you have an old multisync VGA-monitor which accepts low frequencies (15,6 kHz horiz., 50/60Hz vert.) you could build a Scart-to-VGA-cable for your DVD-player and it'll work! Most DVD players with Scart-connector have a menu where you can choose between S-Video and RGB output. There are also TV-sets where you can choose between S-Video and RGB-input. If the TV has more than one Scart connector the first one is usually the RGB-capable one. Only the latest hi-end models have more than one RGB-capable Scart-connector, which is a shame since RGB rules now. Set-top-boxes, game-consoles and DVD-players usually provide RGB. When the 21-pin Scart connector was introduced there was just composite video and RGB. Later S-VHS and Hi8 were introduced which used y/c component video. There were no pins left in the Scart-connector, so S-Video and RGB had to share one or two pins. That's the reason you have to decide which to use. Christoph | ||

Hi I tried to view my PC on my television through RGB via SCART. I spliced hsync and vsync together (no circuit - i was told it'd work this way), and tried finding a suitable resolution with powerstrip. The idea was to find a resolution/refresh rate combo that would be acceptable for stereoscopic content with shutterglasses. I had no success - only some green lines flickering across the tv screen. So I gave up on it. Has anyone had succes with this? If so, how did you do it- and how did stereo look? Alex | ||

VGA-frequencies are far too high for a TV. Christoph |
