Nvidia driver wont detect correct resolution of monitor via DVI on Ubuntu
Raw
nvidia-resolution-dvi-fix.md

If you have a Nvidia graphics card and have the Nvidia proprietary dirver installed and notice that it wont detect monitor information over DVI then try apply this:

First run nvidia-xconfig in a terminal to generate the /etc/X11/xorg.conf file.

Then you need to lookup your monitors specifications to find its Horizontal and Vertical refresh rates.

The edit the xorg config like so:

sudo nano /etc/X11/xorg.conf

Locate the line that has this text Section "Monitor"

Correct the information under those sections. I just did the bareminimum:

Section "Monitor"
    Identifier     "Monitor0"
    VendorName     "Unknown"
    ModelName      "Unknown"
    HorizSync       30.0 - 80.0
    VertRefresh     56.0 - 76.0
    Option         "DPMS"
EndSection

save the file out with ctrl + x and then press y.

Reboot the computer and then more resolutions such as 1920x1080 will show under the display settings.
