I have following issue: I've purchased dell xps 13 9360 (i7 7-th gen) with 4k (3200x1800) monitor, ubuntu gnome 17.10 installed on it, and want to plug my external HD monitor (1920x1080) using hdmi (type-c -> HDMI) cable. The issue I'm falling in is that, on the external monitor icons, windows and everything is scaled up.
I've searched through the similar problems and there were "solutions", using xrandr, or change window scale factor using dconf editor etc. As a result nothing has worked, but I hope that there may be some updates.
So please share your thoughts or solutions (if you have one), since I know that there should be some solution, because it works on windows 10, pretty nice. But I'm not windows user, so I would like to make my ubuntu behave well and get windows-like behavior.
if extra details are required, please ask.
