What's the issue you have with high DPI monitors? I've used 3200x1800 14" screens way back (on Fujitsu U904 when that came out: I found a review from 2014 online), 4k 24" Dell when it still required two DP cables for 60Hz, and more recently 4k 14" screens on X1 Carbon: while you need to configure scaling (I prefer 125% or 150% for UI elements, and fonts further increased by a factor of 1.4x), most programs work well with that (including non-native UI peograms like Firefox, LibreOffice or even Emacs).

For a long while there was an issue with multiple monitors which you want to configure with different settings: you couldn't.

I believe that is also fixed today with Wayland but I mostly stick to a single monitor anyway.
