Different Scaling with two monitors

My main monitor is 4k resolution. The secondary is on 1080p. I need to scale the 4k to 200% so that things are not too tiny. The problem is, that it seems to be not possible to edit different scaling for two monitors in Xorg. Since Im using prop nvidia-drivers Manjaro does not let me use Wayland.
So Im looking for a way to get different scaling in Xorg.
Your help would be much appreciated!

Yeah that’s a known issue and the current workaround is to do it the old-fashioned way:

  • Change the resolution on the 4K monitor to 1080p as well

That way:

  • everything is scaled perfectly
  • you still get to use the high refresh rate of the 4K monitor

until you can afford identical monitors.
