Inspect a monitor for dead or stuck pixels

Open dead pixel inspection. Clean the screen according to its manufacturer’s instructions and use normal brightness.

Inspect every field

Black reveals bright points; white and primary colors expose dark or incorrectly colored points. Enter fullscreen and hide controls while inspecting. Tap the pattern to restore them.

Check twice

Change field color and viewing angle. Dust and screen protectors can resemble a defect. A persistent dark point may indicate a dead pixel; a bright colored point may indicate a stuck subpixel. The browser cannot identify either automatically.

Document before attempting repair

Photograph persistent defects and consult the seller’s pixel policy. Do not press on the panel. This site does not promise to revive pixels. Compare larger patches using uniformity fields and backlight inspection.
