I have a Surface Pro 3 laptop (running Ubuntu Gnome) with two external monitors.
The laptop's screen has a resolution of 2160x1440, and the two monitors are 1920x1080.
The Surface Pro (
eDP1) is on the left, and the two other monitors (
DP2) are on the right, with the central monitor being the primary monitor.
This causes everything on the Surface Pro display to be extremely small, so I want to change the DPI of this display to make everything a bit bigger.
However, I have no idea how to do that.
I've tried using
xrandr, but I can't get it to work.
Can anyone help?
