I have a touchscreen Dell XPS 9550 and an external 27" Dell screen.
How can I make sure the external monitor doesn't scale everything up as it currently is by 2x?
The XPS is HiDPI whilst the screen is FHD. Output from
xrandr -q reveals the following:
eDP1 connected primary 3840x2160+2560+0 (normal left inverted right x axis y axis) 350mm x 190mm
HDMI1 connected 2560x1440+0+214 (normal left inverted right x axis y axis) 600mm x 340mm
I initially followed the instructions on https://askubuntu.com/questions/393400/is-it-possible-to-have-two-different-dpi-configurations-for-two-different-screen however Pantheon keeps resetting itself, and I'm unable to set the desired dimensions ( adjusted the calculations based upon the output above.
I'm trying to set the XPS to the right of the monitor.
