I recall back when I had an ATI card and ran Windows that ATI had a driver option to use lower DVI frequencies for large monitors, and that solved similar issues for me at the time. Unfortunately, I don't see anything similar in Appendix B of Nvidia's README (X Configuration Settings). Does anyone know of a fix for the DVI frequency?
I'm using Debian Testing with Xorg 7.2 and Nvidia's 100.14.11 driver, by the way.

For posterity, when seems to have worked in my case was to physically isolate the DVI cable as much as possible from other cables. I suspect a power cable or power supply was creating interference in the DVI.
