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 :)

I get what you are saying, however at 120", less than 20 feet away, you can literally see the individual pixels (especially at 1080). It absolutely does make a difference under the right circumstances, that is empirically true. You can test it yourself if you are skeptical but I'm telling you for a fact that on resolution alone there is a noticeable difference for anyone who has 20/20 vision on a big screen closer up.

I mean sure, but you can say the same about any resolution possible. At some microscopic distance on a 42k display you will be able to see the difference. Your scenario here is pretty much “if you use a display in a manner it wasn’t intended then you’ll be able to see the difference in resolution when you compare it to a display that is used in the manner intended”
