Earlier quoted context omitted.
I have a Dell 24" 4k, which I got about two years ago, and back then, only Dell and Asus had a 24" option. I have no idea why manufacturers are so insistent on selling 27" 4k monitors; 2x scaling looks too big, and non-integer scaling looks blurry because the resolution is too low for 27". My theory is that most people, for all practical purposes, are blind.
It seems the only option available is the Lg $700 monitor. So at 24” 4K does everything looks nice and smooth without scaling like a built in Retina display?
I spend most of my day watching a screen, and I want it to be perfect. Because of this, I would be tempted to buy the new Apple display. However, buying an iMac makes much more economic sense. I have no idea why display manufacturers can't get the details right.
Windows and Gnome look gorgeous at 2x rendering. macOS does too, but that's expected.
