A couple of thoughts: * That's exactly the point. I don't want to give up on my 4k resolution, I specifically bought a laptop with high resolution. * I'm running Ubuntu on my Dell XPS 15. I solved the problem by scaling the external display (--scale 2x2 in xrandr), which also solves the problem but allows me to keep the 4k resolution on the built-in display. The only issue is, that select programs with nonstandard UI components (telegram client) break, everything else works like a charm * Thanks for the gist.

BTW, this is the command I'm using:

sudo xrandr --output DP-3 --scale 2x2 --mode 1920x1080 --fb 7680x2160 --pos 3840x0 --output eDP-1 --mode 3840x2160 --pos 0x0

DP-3 being my external full-HD display, placed to the right.

What errors do you get if you try without sudo? I have a script that runs xrandr commands, but doesn't need sudo.
