Technically 1600x1200 is the maximum resolution supported by single-link DVI without reduced blanking (or 1920x1080). With reduced blanking you can eek 1920x1200 out, but only if the TMDS transmitter can push out the full bandwidth of single link DVI cleanly. Many older TMDS transmitters aren't able to do so. In fact, nVidia's natively designed ones weren't able to do so until the 7-series cards. ATI was better, but I was unable to push 1600x1200 out of a 9600 Pro I had a long time ago without getting weird digital artifacts and flashing. Some monitors deal with it better than others, too.EDIT: If I turn off either of the "reduce DVI frequency" or "alternate DVI mode" in CCC, there are fewer aberrations on the screen, but it does not disappear entirely if I turn both off. Turning either one or the other off seem to have the same effect. Both were enabled by deafult.
Changing the resolution to 16x12 fixed the problem. I'm now back at 1920x1200. This is obviously not a long tern fix, though.
