Not sure if this is the right place for this question, as it is driver related and not 3D Vision related, but I suspect that this group of people will know the answer if anyone does 8-)
I have an "old fashioned" active stereo display using quad buffered stereo and the stereo DIN out on the Quadro 5600 card. I have two projectors that are a side by side tiled display with a blended pixel overlap (180 pixels roughly). Each projector is being driven at SXGA+ resolution using active, quad buffered stereo from a single Quadro 5600 card. The two displays combined give me a stereo resolution of 2620x1050 (2 * 1400 - 180 = 2620) pixels.
My problem is with the new nVidia drivers on Windows 7. On Windows XP, there was a capability to do a screen overlap in the nVidia driver directly. Thus I could tell the driver there was a 180 pixel overlap in my two displays and it would automatically span the desktop across my two displays seamlessly. I just upgraded to Windows 7 and a new nVidia driver (267.05) and this feature is no longer supported. This causes me a serious headache (I basically can't use my full screen display since the blend/overlap doesn't match). Does anyone know of a way to reproduce the Windows XP behaviour on Windows 7. It looks like Mosaic might be able to help, but from what I have seen thus far there still isn't a way to tell a horizontal span across two monitors to have an overlap. And I am not "Mosaicing" across two graphics cards, but across dual outputs on a single graphics card. Am I missing something???
Any help greatly appreciated. If this is not supported under newer OSes then I guess I will have to go back to WinXP. The need to do this seems very odd given the increase in need to support multiple displays... This would not be good if I have to go back to WinXP!!!
