A nice place to discuss rumors, happenings, innovations, and challenges in the technology sphere. We also welcome discussions on the intersections of technology and society. If it’s technological news or discussion of technology, it probably belongs here.

Remember the overriding ethos on Beehaw: Be(e) Nice. Each user you encounter here is a person, and should be treated with kindness (even if they’re wrong, or use a Linux distro you don’t like). Personal attacks will not be tolerated.

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 :)

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.
