Screen tearing with Nvidia driver

[filo]

You could try with xrandr like here, setting DP-0 to 144

Refresh rate resets after boot

type xrandr -q to find out what you need to put after "--output". Then try this: xrandr --output your_output --mode your_resolution --rate your_refresh_rate If after reboot the parameters are not correct, you can always set the above command as a script and set it to run automatically at boot through the system settings (not the most clean solution but it will work).

Maybe check also the Arch wiki
