Added custom refresh rate to my monitor; how do I make it permanent?

In Display Configuration, 75 Hz doesn’t display as an option for my monitor. It is in fact a 75 Hz monitor.

I added 75 Hz as an option to my monitor via xrandr, it’s working fine, however, I have to run through the process again on reboot.

How do I make these settings permanent?

Thanks! :grinning:

Custom Monitor Refresh Rate

  1. Get target monitor via xrandr.
  2. Generate refresh rate entry via
cvt 1920 1080 75

Modeline "1920x1080_75.00"  220.75  1920 2064 2264 2608  1080 1083 1088 1130 -hsync +vsync
  1. Use output from Step 2 and create new refresh rate mode via
xrandr --newmode "1920x1080_75.00"  220.75  1920 2064 2264 2608  1080 1083 1088 1130 -hsync +vsync
