First one - IntelliJ (which Android IDE is based off) supports scaling nowadays.

Try running

  xrandr --dpi 200
(try it with lower values like 144 if that's too large)

and restart Android IDE.

Second monitor: you need to render the second screen at High DPI and then downscale. Example script (with two monitors):

  xrandr --output eDP-1 --off
  xrandr --output DP-2-1 --left-of eDP-1
  xrandr --output DP-2-1 --right-of DP-2-2
  xrandr --output DP-2-2 --scale 1.5x1.5 --pos 0x0
  xrandr --output DP-2-1 --scale 1.5x1.5 --pos 2880x0


Hi, and thanks for the hints. These were discussed over at arduino.cc a while back, and I had some small measure of success with them, but it was very messy to get this working with the apps that needed them (only). And, ultimately, it broke savagely with problem #2 -- when I move between displays with drastically different DPI's. I don't think that second problem is totally intractable ... but I do think it's a long way of being fixed (on any platform).

EDIT: Oh, and yes, the 'scaling support' feature was added into the version that I was trialling of arduino IDE a while back (I forget the #'s). It was meant to have been resolved, but I noted on the various forums that lots of people (including myself) couldn't get it to play nice. Investigations were on-going whether it was a KDE, xorg/wayland, nvidia, phase of the moon, or some other related problem.


Did you try it? What issues are remaining? Links to the bug tracker reports? Legitimately curious.
