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

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 :)

Are you sure about that? You likely use DPI scaling at 4K, and you’re likely limited by physical screen size unless you already use a 50” TV (which is equivalent to 4x standard 25” 1080p monitors).

8K would only help at like 65”+, which is kinda crazy for a monitor on a desk… Awesome if you can swing it, but most can’t.

I tangentially agree though. PCs can use “extra” resolution for various things like upscaling, better text rendering and such rather easily.

Truthfully I haven't gotten a chance to use an 8k screen, so my statement is more hypothetical "I can see a possible benefit".

I’ve used 5K some.

IMO the only ostensible benefit is for computer type stuff. It gives them more headroom to upscale content well, to avoid anti aliasing or blurry, scaled UI rendering, stuff like that. 4:1 rendering (to save power) would be quite viable too.

Another example would be editing workflows, for 1:1 pixel mapping of content while leaving plenty of room for the UI.

But for native content? Like movies?

Pointless, unless you are ridiculously close to a huge display, even if your vision is 20/20. And it’s too expensive to be worth it: I’d rather that money go into other technical aspects, easily.
