Agreed. I tried 24k 4k screen as soon as they came out (required two DP cables to run at 60Hz at the time), and turning subpixel rendering off, I could see jagged edges on fonts from normal sitting position (I am shortsighted, but at -3.25 I always need correction anyway, which brings my eyesight to better than 20/20). At 27" or 32", DPI is even worse.

And MacOS has removed support for subpixel rendering because "retina", though I only use it when forced (work).
