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 :)

Depends on the source material, the distance you look and quality of the panel. 4k is just more resolution than HD. This does not really need a study.

It sounds like the study actually did include display distance, and gave different requirements depending.

My point is, I could do a study too and claim that 4K/8K TVs are much better than HD to your eyes. Its just the setup and source that makes the difference.

Now that I've actually looked at the study, what they did is make an apparatus with continuously adjustable distance to display and try to get people to distinguish scaled, fairly similar clips until they couldn't anymore.

Actual maximum pixel-per-visual-degree values varied quite a bit based on colours involved and the like. And like @GenderNeutralBro@lemmy.sdf.org said, they framed the results the opposite way to the article - human vision can distinguish more than previously thought.

Seconded. Really depends and very dependent on the person and source.

I noticed quite a bit with my OLED TV sitting about 7 feet away from it. My wife doesn't care, and she would say it doesn't make a difference until we watched something that was truly done well like Dune.

There's too many variables here to say "doesn't make a difference". We can safely say "diminishing returns" which is universally true, but not that there is no change

came to say it depends on how far away.
