Just do this:

For ordinary laptop with:

  • primary ID : LVDS1
  • Resolution : 1366x768

and want to upscale resolution to 2049x1152 with no invisible border mouse, put this on your terminal:

xrandr --output LVDS1 --mode 1366x768 --rate 60 --fb 2049x1152 --panning 2049x1152 --scale-from 2049x1152

That goes for HDMI, etc. It works everywhere.


It seems that

xrandr --output HDMI-1 --scale 1.7x1.7 --auto --panning 4352x2448+3840+0 --right-of eDP-1
xrandr --output eDP-1 --auto --scale 0.7x0.7

seems to work fine.
