Just like there is more to cameras than megapixels, there is more to a display than resolution. Simply saying “hidpi” does not necessarily solve the problem.
Pretty poor. At fractional scaling on Windows, expect that even preinstalled applications (Computer Management, for instance) will be very fuzzy. GNOME works fairly nicely, but as usual expect glitches and strange scaling problems with non-GTK applications, multiple monitors, etc.
I continue to prefer a screen where it has a high pixel density but is plenty usable without any scaling.
Dunno about Windows, but on GNU/Linux (Plasma user here) it's pretty solid these days. It's problematic on X11 only when you have multiple screens with different DPIs, but I connect external screens only for movies or slides, so that's a non-issue for me - plus if you're fine with Wayland (I'm not yet, but it's close) it's pretty much solved there.
