Dual screen setup, but experiencing scaling problems?
Dual screen setup, but experiencing scaling problems?
HiDPI works mainly on GNOME and offers the strongest support in the official Ubuntu version. KDE generally ranks lower, though it’s still usable; other options might cause issues unless things have improved. It’s a good idea to tell the person which Desktop Environment you’re using, as this can help more. You can also check the Arch Wiki link provided for more details, even though it’s not Arch itself.
I have two 4K monitors running Ubuntu, and everything functions smoothly. Previously, with just one HD and one 4K, scaling didn’t work well. For better monitor scaling, it seems you should switch to Wayland instead of Xorg—though I couldn’t find Wayland enabled on Mint yet. Wayland is available in Ubuntu 20.04, but you might need to turn it on first.
