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 :)

But that could easily be due to the quality of the projector rather than the resolution. Everyone in here saying they notice differences is completely missing the point. You’d need to compare against the exact same panel type, manufacturer, model year, etc with the exact same manufacturing processes in order to come to this conclusion yourself.

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”
