You fixed yours at the TV end - and that's nVidia's answer.  There used
to be settings at the video card end, and those don't work, apparently
for 8x00 series cards.  In my case I have a plain old CRT TV, and
there's no adjusting for this.  Besides, it works correctly with other
consumer electronics.
