Watching anything happen in slow motion is, generally, pretty rad. Watching a bunch of different TV’s refresh in super slow motion is even better.
The Slow Mo Guys have been doing these kinds of videos for years, and this one is no less fascinating. In it, they capture precisely how different TV’s, from an old CRT to a flashy new OLED UHD 4K TV, refresh the image being displayed. At one point, they slow the whole thing down a mind-bending 380,117 frames per second.
They also get right up on a 4K TV to show off the pixel density and explain how each individual pixel works to display different colours.
