A new study published in Nature by University of Cambridge researchers just dropped a pixelated bomb on the entire Ultra-HD market, but as anyone with myopia can tell you, if you take your glasses off, even SD still looks pretty good :)

But they are much better for energy companies

Study Boldly Claims 4K And 8K TVs Aren't Much Better Than HD To Your Eyes, But Is It True?

The rare exception to Betteridge's Law.

But yeah, this matches my experience. I can tell the difference between 1080 and 4k from my couch if I work at it, but not enough to impact my enjoyment of what I'm watching, and definitely not as much as the difference HDR makes.

Even at computer monitor distance, running a 4k monitor at 1440 with high pixel density is probably going to be a better experience than wrenching every single pixel you can get out of it. Framerate is better than resolution for gaming, for the most part.

If you’ve ever connected a laptop or PC to a television as a monitor, the benefit of 4K for text readability is incredibly apparent.

If this isn’t your use case, and you’re not right up against your screen, 1080p is more than good enough; not like most content is coming down on 4K unless you’re paying extra, anyways.

My PC is on a 40" TV at 1920 x 1080. Looks great to me, and my eyes aren't so hot.

I stick with 1080p for my Jellyfin library because I can’t really tell much difference on my living room TV between upscaled 1080p and native 4k, at least not enough to merit the huge difference in file size. 4k games when sitting close to my computer monitor, on the other hand, are definitely worth it.

They did get around to saying it's pixel density at the end...

But still, it's human variation. Everybody is gonna be different. I'm not a resolution snob, but anything under 100fps pulls me out of the experience. So usually I just run at 1440, when I have fps to spare I'll put all the settings up rather than go to 4k.

Other people would rather 30fps at 4 or even 8k

That's why I have a 65" and sit barely 2m from it. Stick on a 4k Dolby Vision encoded file through Jellyfin. Looks fucking great!
