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 :)

The study doesn’t actually claim that. The actual title is “Study Boldly Claims 4K And 8K TVs Aren’t Much Better Than HD To Your Eyes, But Is It True?” As with all articles that ask a question the answer is either NO or its complicated.
It says that we can distinguish up to 94 pixels per degree or about 1080p on a 50" screen at 10 feet away.
This means that on a 27" monitor 18" away 1080p: 29 4K: 58 8K: 116
A 40" TV 8 feet away/50" TV 10 feet away
1080p: 93
A 70" TV 8 feet away
1080p: 54 4K: 109 8K: 218
A 90" TV 10 feet away
1080p: 53 4K: 106 8K: 212
Conclusion: 1080p is good for small TVs relatively far away. 4K makes sense for reasonably large or close TV Up to 8K makes sense for monitors.
