Ultra-HD televisions not noticeably better for typical viewer, scientists say

Research shows 4K or 8K screens offer no distinguishable benefit over similarly sized 2K screen in average living room

Many modern living rooms are now dominated by a huge television, but researchers say there might be little point in plumping for an ultra-high-definition model.

Scientists at the University of Cambridge and Meta, the company that owns Facebook, have found that for an average-sized living room a 4K or 8K screen offers no noticeable benefit over a similarly sized 2K screen of the sort often used in computer monitors and laptops. In other words, there is no tangible difference when it comes to how sharp an image appears to our eyes.
