What to Do If You Find a Dead Pixel

A step-by-step guide for confirming a suspected dead pixel, ruling out dust, and deciding whether to return, repair or keep the device.

Quick answer

If you find a suspected dead pixel, clean the screen, repeat white and primary-color tests, and confirm that the dark point stays in the same physical location. Do not press the panel. Document a repeatable defect and check the seller return window before trying any optional pixel routine.

Confirm that it is a panel pixel

Dust, lint, a protector mark or a tiny scratch can resemble a dead pixel. A true panel defect remains fixed after gentle cleaning and across several solid backgrounds.

Choose the response by symptom

A dark point is more consistent with a dead pixel. A bright red, green, blue or white point is more consistent with a stuck or hot pixel. Software cannot reliably repair a true dead pixel.

Protect the return option

For a new or recently repaired device, record the screen color, brightness and location of the point before the return deadline. Warranty thresholds vary, so use the exact seller or manufacturer policy.

How to verify it

  1. Clean the display without pressing the panel.
  2. Check the same point on white, black, red, green and blue.
  3. Classify it as dark, bright or colored and repeat after a restart.
  4. Save clear evidence and review return or warranty terms promptly.
