Thats a waste of image quality for most people. You have to sit very close to a 4k display to be able to perceive the full resolution. On PC you could be 2 feet from a huge gaming monitor, but an extremely small percentage of console players have the tv size and distance ratio where they would get much out of full 4k. Much better to spend the compute on higher framerate or higher detail settings.

I think higher detail is where most of it goes. A lower resolution, upscaled image of a detailed scene, at medium framerate reads to most normal people as "better" than a less-detailed scene rendered at native 4k, especially when it's in motion.

Wait, are you sure you don't have that backward? IIUC, you don't[] notice the difference between a 2K display and a 4K display until you get up to larger screen sizes (say 60+ inches give or take a dozen inches; I don't have exact numbers :) ) and with those the optimal viewing range is like 4-8 feet away (depending on the screen size).

Either that or am I missing something...

[]Generally, anyway. A 4K resolution should definitely be visible at 1-2 feet away as noticeably crisper, but only slightly.

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.

I still use 4K@24", unfortunately they're getting scarce. 4K@27" is where it's at now unfortunately. But I'll never go back to normal DPI. Every time at the office it bugs me how bad regular DPI is.

[encrypted_bird]

That's fair, but it makes me wonder if perhaps it's not the resolution that makes it crisper but other factors that come along with that price point, such as refresh rate, HDR, LCD layer quality, etc.

For example, I have two 1920x1080 monitors, but one is 160 Hz and the other is only 60 Hz, and the difference is night and day between them.

It’s best to think about this as angular resolution. Even a very small screen could take up an optimal amount of your field of view if held close. You get the max benefit from a 4k display when it is about 80% of the diagonal screen distance away from your eyes. So for a 28 inch monitor, that’s a little less then 2 feet, pretty typical desk setup.

Hmm... I still have my doubts, but you make a good point. I'll have to think on this a bit. Thanks for clarifying!

Assuming you can render natively at high FPS, 4k makes a bigger difference on rendered images than live action because it essentially brute forces antialiasing.
