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 :)

Highly depends on screen size and viewing distance, but nothing reasonable for a normal home probably ever needs more than 8k for a high end setup, and 4K for most cases.

Contrast ratio/HDR and per-pixel backlighting type technology is where the real magic is happening.

Depends on your eyes quite a bit, too. If I'm sitting more than 15' back from a 55" screen, 1080p is just fine. Put on my distance glasses and I might be able to tell the difference with 4K.
