Study Shows the Human Eye Can Not Fully See 8K on Mid-Size TVs

A group of researchers from the University of Cambridge and Meta Reality Labs investigated the number of pixels the human eye can see and whether super-high-resolution TVs like 8K make a difference.

When applying their findings to real-world setups, the team discovered that in a normal living room with a viewing distance of 2.5 meters, a 44-inch TV with QHD (2560 × 1440) resolution appears as sharp as the eye can see.

This means that upgrading to 4K or 8K on a screen of that size won't make a significant visual difference unless you sit closer or use a larger display.

The researchers created an online calculator to help determine the "sweet spot" based on screen size, resolution, and viewing distance.

The calculator includes a reference chart with suggested viewing distances for TVs between 20 and 100 inches.
