HDTVTest: 4K vs 1080p Blind Test Results
I'm not surprised by HDTVTest's finding that 97% of people could correctly identify a 4K display vs. 1080p, but I have to admit that they did it at 9' on a set of 55" displays was surprising. In my experience it's only really obvious after 65". They were fairly scientific in setting up the test to ensure it was as fair as it could be; make sure to click through to get a better understanding of the results and the conditions that generated them. Well done.
Earlier this month, we set out to investigate if the extra resolution offered by 4K over 1080p is visible at normal viewing distance, as part of an Ultra HD and OLED television showcase event organised by British retailer Richer Sounds. A 55-inch 4K UHD (ultra high-definition) TV was lined up alongside a 1080p HDTV of the same size, each displaying content that’s 1:1 pixel-matched to its native screen resolution. Both TVs had their identities masked by custom-built cabinets which were spray-painted black. Standing 9 feet away (enforced using crowd control posts), attendees were then asked to pick out the 4K television after sampling the displayed material.
