I just upgraded to Vista today, and I cannot get 1240 x 1024 resolution. After installing I was able to set the resolution to 1240 x 1024 and even higher. After installing all the updates and my most recent video drivers my highest sported resolution is now 1024 x 768. I have a 19 inch CRT monitor and 2x Gforce 8600 GT going SLI. Please help, I have tried to reinstall my drivers a couple of times, and also have tried to set a custom resolution with my Nvidia control panel where 1240 x 1024 recalled as an error. If anyone knows how to force an unsupported resolution that would be fine, but I would like to fix this problem.
