alt Hacker NewsHow high? What kind of problems?
I very recently upgraded from a dual fullhd to a dual 4k setup and I was genuinely surprised how little problems I had setting everything up to the high DPI displays. I am genuinely interested in hearing what pitfalls might still await me.

I've been running 2× 4k 27" monitors for about a year on Xfce. I set it to 144 ppi and nothing feels weird to me, though I run a custom theme.
Most HighDPI issues on X based DEs is from lack of fractional scaling, which means the scaling needs to happen in the applications instead (with separate configs for each UI toolkit), leading to lots of weird issues with inconsistently scaled UI elements on monitors sized such that integer scaling produces an inappropriate scale.
It doesn't affect all monitors, but some DPIs really don't play well with X. The fractional scaling you get on Wayland leads to some element of blur instead, but that's a far lesser evil, the jank is a bigger issue IMO.
