> The University of Cambridge’s [display resolution calculator](https://www.cl.cam.ac.uk/research/rainbow/projects/display_calc/), which is based on a study from researchers at the university’s Department of Computer Science and Technology and Meta, funded by Meta, and published in [Nature](https://www.nature.com/articles/s41467-025-64679-2) in October, suggests that your eyes can only make use of 8K resolution on a 50-inch screen if you’re viewing it from a distance of 1 meter (3.3 feet) or less. Similarly, you would have to be sitting pretty close (2–3 meters/6.6–9.8 feet) to an 80-inch or 100-inch TV for 8K resolution to be beneficial. The [findings are similar](https://arstechnica.com/gaming/2022/05/does-the-world-really-need-8k-resolution-game-consoles/) to those from [RTINGs.com](https://www.nature.com/articles/s41467-025-64679-2). This is known since at least 2010, because our eyes are limited in optical resolution and in how big a surface we see.
