A 4k monitor is now $300 (new). Used are even cheaper.

I use Gnome 3.36 and many HiDPI issues I was having before are now gone, without any extra configuration.

It is readable but fonts are pixelated, unlike 4k.
My only problem is that macOS has some artificial limitations when it comes to using non-Apple monitors. Like a lower refresh rate. My solution? Use Linux.
