I work for a company manufacturing 3D displays. I am in charge of designing a new interface board to allow our 3D technology to work with DVI video cards at 1920x1200, and we would like to demo using the stereo mode of the NVidia cards. My development system has a Quadra NVS 290.
Our 3D technology requires a full res left and right image, and I imagine would work much like the Planar setup I see discussed in this board. In our case though, no mirrors are required, as the panels are stacked on top of each other in one housing.
The question I have is this. When running in stereo mode, is the DVI output for the Left and Right display synchronized? I.e. is it effectively genlocked for synchronization purposes?
It makes a HUGE difference for me as a hardware designer. If the images are in alignment, and the pixel at top left of BOTH screens is coming out simultaneously on both monitors, then I can do the 3D processing on a pixel by pixel basis. However, if the two monitor outputs of the NVidia card are not in frame alignment, then I have to do hardware buffering in order to align the frames in our hardware, as we in fact need the left and right images to be "genlocked" basically.
Any information or pointers to where I can find out this type of information would be greatly appreciated.
