“compared to a large 4k monitor where you constantly have to fix UI scaling bugs and zoom in/out, force different fonts for shitty web pages etc.”

counterpoint: this doesn’t appear the case with Apple, as they have defaulted their OS entirely to retina-level density now, removed subpixel rendering, and anything non-5K may look off (and you need to go through hoops to make it look well).

As such, I’m typing this in a MacBook with 3x5K displays connected.

Subpixel rendering has nothing to do with any of this: it was messing up on non-RGB pixel layout panels like VA and OLED, and it used to be a simple setting in GNOME (hidden these days unfortunately).

Still, even 5K at 27" is not without noticeable jagged edges in diagonal lines and textual characters (though I've only tried 4K at 24", but that's a similar DPI and angular resolution if at the same distance) if your visual acuity (with or without correction) is around 20/20 or better (mine is better with glasses/contacts).

I hate how the text looks with a Mac on a 4K 32" screen, let alone 4K 42" screen.
