8K TVs
The latest and greatest thing in TVs are new models with 8K resolution. That’s 7680x4320 pixels or four times as many pixels as a 4K TV and 16 times as many as a 1080p TV. Do these new 8K TVs offer a differentiated experience? Can you see the difference?
In other words, simple visual acuity does not tell the whole story on why 8K images look better than 4K even at longer distances. Higher order processes come into play that increase the sense of depth and realness of such images.
 
Two recent studies are confirming this. In one study by Dr. YungKyong Park of Ewha Womans University in Seoul, side by side 4K and 8K 65” TVs were set up and calibrated at 500 nits of peak luminance. Observers were pre-tested to be sure their simple acuity was 20/20 and that they had normal color vision. All 120 observers sat 9 feet from the displays in a dark room – typical nighttime TV viewing conditions. All participants were shown the same 16 images and 3 videos representing a diverse range of visuals.
 
As a result of the study, 8K displays performance was rated 35% higher—with perceived image quality increasing by 30% and depth perception increasing 60% from 4K to 8K.
