I’m also still mourning the loss of subpixel AA with my primary display being 4k@1x. For several versions of macOS it was removed from the System Preferences UI but still available with a defaults command, but I’m pretty sure that’s gone now too.
right, you're not even supposed to use those 4k at native resolution if you want good fonts! some sources still list a couple of manual commands that supposedly enable antialiasing again but I don't think they do anything anymore.
It’s 43” haha. It has roughly the same pixel density as a 27” at 2560x1440.
32” 4k on a m1 mini at a scaled resolution of 2560x1440 looks great.
