Scientists claim you can't see the difference between 1440p and 8K at 10 feet in new study on the limits of the human eye — would still be an improvement on the previously-touted upper limit of 60 pixels per degree

Researchers from the University of Cambridge and Meta Reality Labs conducted a study on human eye perception of display resolutions, finding that at 10 feet distance, a 50-inch screen looks nearly identical at 1440p and 8K resolution. They developed a calculator to determine the point at which increasing resolution becomes imperceptible to the human eye, challenging the previously believed limit of 60 pixels per degree. The study suggests that higher resolutions may not always be necessary as the human eye has limitations in perceiving pixel detail, which could impact display technology development. The findings could influence future advancements in image, rendering, and video coding technologies.
