Came here to echo this. Also, it always amazes me how many people respond to warnings like this (as seen in this thread as well) saying lower-resolution displays look just fine. I returned a M2 Mac Mini solely because it looked so awful on all of my monitors -- I tried 2 different 32" 2k displays, plus a handful of 24" displays. Everything was fuzzy and awful looking. Not something that could be tolerated or ignored... Completely unusable. I feel like this fact is not well known enough.

The fact that so many seem to tolerate "low-res" or "mid-res" displays on the current M-series Macs is really puzzling to me... maybe my eyesight isn't as bad as I thought it was and everyone else's is a lot worse!?

This new M4 mini is tempting enough that I might try a Mac again... but this time I am definitely going to have to budget for a 4k/5k display.
