Hello all,

I have upgraded my virtual reality setup with a Geforce 6800 Ultra and upgrade the nVidia graphics driver for windows XP to 77.72

With my old card/old driver, I was using a custom resolution of 1024x1536 (with gives 1024x768 with a sync doubler to generate active stereo).

The 77.72 says "the custom resolution cannot be added" when I try to add a resolution of 1024x1536, 32 bits, 75Hz.

I have 2 analog screens (1 CRT and 1 Barco tri-tube projector) plugged to each DVI output through a DVI-VGA adapter. I don't know if my DVI-VGA adapter transfer back the EDID informations.

Thanks in advance.

I found a workaround. Using Riva Tuner software I managed to add my custom resolution.
