Added troubleshooting information for monitors which report no or a corrupt edid so save other peoples time with the same issue.
(This problem appeared after installing the proprietary nvidia driver, and was fixed by changing this setting.)
 
=== Override EDID ===
 
If your monitor is providing wrong EDID information, the nvidia-driver will pick a very small solution.
Nvidia's driver options change, this guide refers to nvidia 346.47-11.
 
Aside from manually setting modelines in the xorg config, you have to allow non-edid modes and disable edid in the device section:
