Yes, I have done so using xrandr. However, it does not work by just listing the resolution 1920 x 1080 for the external monitor, I have to add scale 2x2 to the xrandr command.

Even so, the wallpaper background scales oddly, does not repeat in a consistent fashion on the display, and, while I can drag a window opened on the laptop display over to the external monitor and it looks ok, if I maximize it, it does not fill the entire  monitor but only 1/4. If I open eg. a terminal window, it also scales to 1/4 of the surface.

Clearly there is/are bug(s) but where? I surmise it's because the laptop display is UHD at 3840 x 2160 and the external monitor runs at /lower/ resolution. Most often the opposite is true.

I would love to help find the bug/bugs and get this working!
