I don't understand you comment. My 4k 27" renders fonts just fine.

If you go to true 2x scaling, things will be the same size as 1920x1080@1x on a 27". For me, that's HUGE and you don't get enough screen real estate for a 27". If you use 1.5x scaling you will lose sharpness because things won't line up to pixels perfectly.

Ah I see what you mean. I use fractional scaling without an issue.

Same here - have three 27inch 4k Ultrafine monitors and fonts render just fine (and are generally amazing).
