Using it daily on my 1920x1200 laptop screen in Linux and works just fine.
Zed developers themselves acknowledge the blurry font issue [1], so either you just don't notice blurry fonts or 1920x1200 on a small laptop screen is HiDPI-enough to kinda hide the blurriness.
My desktop monitor is 1920x1080. On my computer and display; Vim, Emacs and VSCode are all able to render their fonts crisply while Zed is a blurry mess.
Are you using dark mode? To me, text looks absolutely awful in light mode, but okay in dark mode. Still noticeably worse than any other editors, though.
This may be it.
I use it in dark mode and I am considerably less picky about font rendering than many people commenting on such threads.
Combined, while I can see a difference if I look closely, it doesn't bother me.
