Yes, but since you can get 4k on everything from 24" to 84" you'll want to choose between more space or bigger fonts depending on the setting. macOS can do 'fractional scaling' when the integer scaling isn't to your preference, but the implementation works by rendering to a much higher resolution internally and then scaling down which needs a beefy GPU to run without noticeably overhead.

Anything bigger than 24" or so and the blurriness gets bad. The pixel density just isn't quite there.

Depends how close you are to it, though, I would think

I am reading this on 32" 4K monitor (2 of them actually are hooked to a gaming laptop). I do not notice any blurriness.

[bluedino]

Are you running a non-default resolution?

[FpUser]

I am running those at native 4K resolution. Frankly I do not get a point of buying 4K monitor to run it at lower resolution

[FpUser]

Yep this definitely deserves downvote. I guess 4K must be blurry by definition
