Add Custom Resolution with xrandr

 

Run xrandr to view display details

Run cvt 1920 1080 to get a modeline such as below:

"1920x1080_60.00" 173.00 1920 2048 2248 2576 1080 1083 1088 1120 -hsync +vsync

Then add the above line to the –newmode command, example:

sudo xrandr --newmode "1920x1080_60.00" 173.00 1920 2048 2248 2576 1080 1083 1088 1120 -hsync +vsync

Then add mode:

sudo xrandr --addmode DVI-0 "1920x1080_60.00"

To ensure the change is persistent, add the last two commands to ~/.profile (“sudo nano ~/.profile”) example:

xrandr --newmode "1920x1080_60.00" 173.00 1920 2048 2248 2576 1080 1083 1088$
xrandr --addmode DVI-0 "1920x1080_60.00"
