Perhaps try a 5k/27" at 150%, or look for visual acuity correction :)

FWIW, I could see jagged edges on 4k at 24" without subpixel rendering, 27" is worse. Yes, even 4k at 32" is passable with MacOS, but Linux looks better (to the point that 4k at 43" has comparable or slightly better text quality to 4k at 32" for a Mac).

I am trying to get a 55" 8k TV to work well with my setup, which might be a bit too big (but same width as the newly announced 6k 52" monitor by Dell), but it's the first next option after prohibitively expensive 32" options.
