My first 4K screen was a 24" computer display and let me tell you, the difference between that and a 24" 1080p display is night and day from 1-2 feet away. Those pixels were gloriously dense. Smoothest text rendering you've ever seen.

I didn't use it for gaming though, and I've "downgraded" resolution to 2x 1440p (and much higher refresh rates) since then. But more pixels is great if you can afford it.

It's one thing to say you don't need higher resolution and fewer pixels works fine, but all the people in the comments acting like you can't see the difference makes me wonder if they've ever seen a 4K TV before.
