Scaling two different monitors HiDPI

I have two monitors. One 4k, the other 1080p. The 4k is on 200% so that icons etc have a reasonable size. Problem is that the 1080p Monitor always scales as well and then is displaying everything "too big".
I followed the ArchWiki article "HiDPI". So I think xrandr could be the solution.
If I do

xrandr --output DP-2 --auto --output HDMI-0 --auto --scale 2x2 --left-of DP-2

The result is what I want except that aprx 1/3 of the maindisplay is mirrored on the side display. When I try to fix it with

xrandr --output DP-2 --pos 3840x0

The part of the maindisplay is not shown on the side display anymore but the maindisplay is not scaled to 200% anymore....

I would be glad, if anyone has an idea on how to fix it. Thank you!
