Dead Pixel Fixer
Attempt to fix dead pixels by cycling colors. Run the browser-based check and follow its prompts to review the result.
Color cycling will flash changing colors for up to 1 minute and stop automatically. Stop the test if the flashing is uncomfortable.
Color cycling may help a stuck pixel recover, but it cannot repair physically damaged pixels.
Tool guide
About Dead Pixel Fixer
Cycle bright colors across the display in an attempt to make a stuck pixel change state. This may help with some stuck pixels, but it cannot repair a physically dead pixel and results are not guaranteed.
How to use this tool
- 1Read the flashing-color warning and choose a short test duration.
- 2Start the color cycle, then move the pattern over the affected area if needed.
- 3Stop the run if you feel discomfort; check the display after the cycle ends.
How the tool works
The page displays full-screen or moving color patterns at a rapid interval for the selected duration. It does not inspect or control the physical pixels; any change depends on the display panel itself.
Worked real-world example
A pixel that stays bright on one color may appear to change during the cycle, but this tool cannot confirm hardware repair.
Common scenarios and use cases
Try a brief visual pattern on a suspected stuck pixel before deciding whether to contact the display maker.
Important details and limitations
Flashing colors can trigger discomfort or photosensitive reactions. Use a short duration, do not watch at close range, and stop immediately if you feel unwell. Dead or damaged pixels may need service.
Check the output unit as well as the number. If the result will be reused in another calculation, retain full precision where possible and round only at the end. For measurements governed by a technical specification, use the standard and tolerance required by that document.
