Stuck Pixel Fixer
Rapid color cycling over a stuck pixel can sometimes free a frozen subpixel. Drag the flash area over the pixel, pick a speed and duration, and re-test when the timer ends.

Read before starting
- ⚠ The flash area blinks rapidly. Do not use fast mode if you are sensitive to flashing lights.
- This tool targets stuck pixels (colored dots on black). Success on truly dead pixels (black dots on white) is very unlikely.
- A fix is not guaranteed. For a new device, a return or exchange is usually the better first move.
- Do not press or massage the panel — pressure can create new defects.
How it works — and its honest limits
A stuck pixel still receives power, but one or more subpixels are frozen in the on state. Cycling the area through rapid color changes forces those subpixels to switch repeatedly, which can free a stuck transistor. This only applies to stuck pixels: a dead pixel receives no power at all, so no on-screen pattern can affect it. Unsure which you have? Read dead pixel vs stuck pixel or run the two-minute check first.
Recommended routine
- Run the Dead Pixel Check and note the stuck pixel's position.
- Drag the flash area so it fully covers that position.
- Run a 10-minute session at medium speed.
- Re-test. Still stuck? Try one 20–30 minute session.
- No change after that: document it with a report and check your return window or warranty.
