Resolution Stuck at 640 x 480 after NVIDIA Driver Installation

For some reason, after I installed the new NVIDIA drivers on CentOS 7, it stopped recognizing my monitor. Driver broken? A slight hack was required.

In /etc/X11/xorg.conf, look for these two lines :

HorizSync 28.0 - 33.0
 VertRefresh 43.0 - 72.0

and replace them with

HorizSync 30.0 - 83.0
 VertRefresh 56.0 - 75.0

Only by doing this, I was able to change the screen resolution in NVIDIA X Server Settings. For the exact values to put for HorizSync and VertRefresh, consult your monitor’s manual.
