They have a "Resolution limit matrix" on their free calculator page ( https://www.cl.cam.ac.uk/resea... ) and a 4k or higher resolution is indicated as noticeable by your eyes for more than half of the chart! The summary only works for the smallest of tvs 20 inches and at 30 inches it's 50/50 depending on your viewing distance. But 40 inches or above and you should really be considering something with more resolution depending on your viewing distance.
