Wayland has still no way to set DPI of multiple monitors. The fonts look terrible on it. I had to move to KDE Plasma on X11 ever since GNOME started forcing Wayland on us.
I guess I have to buy a 4K monitor in future.

KDE had the setting to allow X11 apps to scale themselves (no more blurry XWayland apps) years ahead of GNOME.
Notice the date.. 1996
(for those that didn't click the link, that is the X11 security extension which address all that, and it was published ~30 years ago).
I suspect the original commenter had an issue with GNOME specifically, as I've noticed it too, on Wayland native apps. GNOME handled fractional scaling poorly, and fonts didn't align to the grid right and looked fuzzy at anything that's not 1x or 2x scale.
KDE got this right from day 1.
I set DPI so that a 15pt font occupies 15pt physical space on screen. Not sure how to set DPI using fractional scaling.
I don't know whether GNOME supports anything similar, unlike KDE they really don't like giving users very many configuration options.
It does, but not every DE expose that functionality. There is some command that should be DE-agnostic like wlr-randr that should allow you to do that.
