Hello, I would like to know any opinions ( and some reasons of them...)about which is the best graphic card for dual genlocked outputs, for dual passive stereoscopic projection. It s important that the two outputs signals, from extended desktop mode, are in synchro. Can you recommend me the best possible graphic cards for this? Thanks in advance ! Bernardo | ||

If I'm not mistaken the Nvidia driver could handle this, you only have to do some modifications in regedit. Ofcourse the more powerful card you have the better. So the Geforce family would be the best choice. "for setting StereoViewerType open regedit and go to HKEY_LOCAL_MACHINE / SOFTWARE / NVIDIA Corporation / Global / Stereo3d/ set variable "StereoViewerType" to the value "4"." | ||

I've understood from other posts on this forum that nvidia quadro cards don't have synchronized outputs (different RAMDACS on the two outputs), so they wouldn't solve your problem. I guess two high-end cards with genlock would do, but I'd like to hope there's a cheaper answer... I must be dreaming. | ||

Why do they have to be in sync if your doing passive stereo? I thought that was a non-issue. Did I mention I'm nosey? John | ||

Well I don't know Bernardo's reasons, but mine are related to motion artifacts : if you want VR simulation, then you need perfect sync between both stereo channels otherwise you get wrong motion signals. I reckon it's less a problem for gaming or video since precise object motion is less relevant. Peter | ||

Thanks for the replies. Now, I have a problem, and I wanted to ask you something: I am using the Matrox Parhelia™ PCI 256 MB graphic card, with a P IV with 3,06 Gighz of precessor, and 2 Gigbytes of RAM memory, for a test. I would want to play a video of 1600 x 600 in "Extended desktop" mode, so half of the signal ( 800 x 600) goes to one LCD projector and the other half to another ... ( side by side format) The problem is that the reproduction in the Windows media player, Quick time, etc,., is not "fluid" or soft... used an uncompressed Avi file. ( 4 Gigbytes for 1,5 minutes) When we compress the signal it is played correctly, but the quality is lost ( 200 Mgb) I wanted to know what we can do in order to reproduce a very high quality large video ( even a 2048 x 768 avi file) without too much lost of quality and in a continuos and soft way... ( not jumps) What is the main factor on video reproduction ? Is it the Graphic card? The ram? Can you help me with it? If there isn t another way than compressing ther file: Do you know a very good and lostless compression codec to use? Thanks and best regards, Bernardo |
