It is much more likely it isn't able to read EDID at all. Do you see something like:
# grep EDID /var/log/Xorg.0.log (WW) NVIDIA (GPU-0): Unable to read EDID for display device CRT-0 (--) NVIDIA(0); --- EDID for CRT-0 --- (--) NVIDIA(0): No EDID Available. (--) NVIDIA(0): --- End of EDID for CRT-0 --- # This is what I see using a VGA cable with the DDC pins purposely broken off. For this case, run nvidia-xconfig and let it generate xorg.conf. You may need to adjust the HorizSync and VertRefresh lines to match your display. Add the desired video mode to the Modes line. I have a request into NVIDIA to expand the range of default resolutions when EDID cannot be read, so no xorg.conf file is needed.
