Your config has # Option "Dac6Bit" "False" # Option "Dac8Bit" "True" Since the VGA connector is giving the correct output, I don't think you should need to uncomment these lines, but the DVI output is behaving as if you had: Option "Dac8Bit" "False" or Option "Dac6Bit" "True" I guess that the DVI output isn't getting this right. I don't have an 8500, or much time for this sort of thing, but *if* I get around to it I'll see if it happens on a 7000 or I can see any bugs in the code. -- Dr. Andrew C.
