I'm also having this problem on my 14" Lenovo Thinkpad T61p (with Nvidia Quadro FX 570M video card, LCD native resolution is 1400x1050), and since it's a laptop, I can not get informations like bandwidth/frequencies of the LCD. Although I did find something that may be interesting: when running the open source mesa driver, I can set the monitor into 1400x1050, 1024x768, 800x600, 640x480, however the resolution 1280x960 is missing, on the other hand, when I use the restricted driver (both 169.12 and 173.14.05 via EnvyNG), both 1400x1050 and 1280x960 is selectable, but the resolution of 1024x768 and 800x600 is missing, instead I see some weird resolutions like 800x512 or something.
Anyway, attached here is a bug report log file that I generated using "startx -- -logverbose 6" and "nvidia-bug-report.sh" (comes with the restricted Nvidia driver ), and part of it reads:

I suspect the HorizSync value is wrong, but I don't know much about the EDID stuff. The detailed bug log file is attached.
