the thread referred to here might be interesting as well:

"Re-thinking DPI and scaling (Re: Physical vs logical DPI on X)"

TL;DR: pixel resolution ignores the physical screen size but limits how
small details can be rendered, DPI ignores the viewing distance meaning
that you don't actually know if something n millimeters high is legible
or not even at infinite pixel resolution.

Then add systems with heterogeneous outputs. Also accessibility for
people with poor eye-sight (maybe somehow factor in user interface
