Finding dead and stuck pixels.
Find dead and stuck pixels, banding and uneven patches: your screen filled with plain colours and ramps, in your browser. Nothing is sent.

A new screen is worth checking before the return window closes.
Plain colours.
Black shows stuck pixels, lit when they should be dark; white shows dead ones; red, green and blue show a pixel with one colour missing. Clean the screen first: dust looks like a dead pixel.
Ramps and grey.
A grey ramp and a colour ramp show steps or bands where they should be smooth; plain grey shows patches lighter or darker than the rest.
No page can fix them.
Pages that flash colours promise to fix stuck pixels; nothing a page draws can repair a pixel, so this test only shows them.
