Gamers have a new argument in screen resolution debates.
Researchers from the University of Cambridge, in collaboration with VR and AR product specialists, conducted a study on the capabilities of human vision.
The study found that the human eye can perceive black and white pixels at a resolution of up to 94 pixels per degree and up to 89 pixels per degree for red and green patterns, but only 53 pixels per degree for yellow and purple colors.
A special calculator was developed that takes into account various factors such as resolution, distance from the screen, and screen size. This allows for extrapolation of the study.
According to these calculations, when viewing a 50-inch screen from a distance of approximately 3 meters, the human eye simply cannot distinguish an 8K image from a 1440p one.
The calculator shows that for a 50-inch display with a resolution of 1440p, viewed from a distance of 10 feet [about 3 meters], only 1% of users will notice a difference between this image and a "perfect" image [reference]. At 4K resolution, this number becomes 0%; naturally, 8K will be the same.
Co-author of the study, Professor Rafal Mantiuk from the Department of Computer Science and Technology at Cambridge, stated:
The more pixels on your display, the less efficient it is, the more expensive it is, and the more computing power it requires to operate. So we wanted to know the point at which further improving the display resolution no longer makes sense
