This set leans into screen nostalgia. The test card recreates the broadcast colour bars stations showed off-air; the TV static animates the snow you'd get with no signal. The dead-pixel test cycles solid colours across the whole screen so you can spot stuck or dead sub-pixels on a monitor you're checking.

Frequently asked questions

Can a screensaver check for dead pixels?
Yes. The Dead Pixel Test fills the screen with solid red, green, blue, white and black in turn. A pixel that stays the wrong colour on a solid field is stuck or dead.
