I changed my graphics card over the weekend to a 6800 - used to have a Radeon 9600. With the ATI card I was able to use Powerstrip to set a resolution of 1024x768 at 50Hz over DVI into a Pioneer 43MXE1 . Tried to set up the 6800 with the same settings, and I lose the signal (I've tried FRC mode 1 and mode 2). Does anybody know if the Nvidia drivers prevent 1024x768 at 50Hz? I'm using the latest drivers.
