Dead-pixel check

“Dead” pixels—defective pixels on a liquid crystal display (LCD) that are not performing as expected. Variations of dead pixels: dark dot, bright dot and partial sub-pixel defects.

Below you may see examples of dead-pixels:

Clean the screen carefully with a soft cloth and click “Start test”. Press “F11” key if your browser window doesn't switch to full screen automatically. Press “Esc” key to exit fullscreen mode and to stop test and return to this page. Make left button click or press “space” to change test-screen.

Pixels are very small so yoo have to look carefully all test screens. Let your eyes accommodate to screen brightness.
