Instructions
  • Switch to fullscreen so the test colors cover the entire display.
  • Inspect the screen closely. A dead pixel stays dark; a stuck pixel shows the wrong color.
  • Tap Next color or use auto-cycle to review each shade across the panel.
  • Repeat the test at different brightness levels for thorough checks.

About Dead Pixel Checker

Dead Pixel Checker cycles bold solid colors to expose faulty pixels that might hide during normal use. Inspect the screen with the lights off and adjust brightness to see subtle issues.

  1. Enter fullscreen and ensure the room lighting lets you view the screen clearly.
  2. Check white and black screens for dead (dark) or bright pixels that remain on.
  3. Review red, green, blue, and secondary colors to catch stuck subpixels.
  4. Note any defective areas for warranty claims or manual pixel fixing attempts.
