How to use it
- Find the pixel first with the dead pixel test. A stuck pixel is always the same color (red, green, blue or white).
- Pick Flashing box, set a time and press Start. You will see a flashing light warning first.
- In full screen, drag the box over the stuck pixel. Drag the round handle to resize it, or use the arrow keys and + and -.
- Let it run for 10 to 30 minutes, then check the pixel again. You can repeat a few times.
- For faint ghost images, pick Slow color cycle or Black and white wipe. These do not flash.
Do not watch the flashing box. Start it and look away or leave the room.
What it can and cannot fix
| Problem | Can this help? |
|---|---|
| Stuck pixel (always red, green, blue or white) | Sometimes. Rapidly switching the pixel on and off can free a subpixel that is stuck. It does not always work, and no tool can promise it. |
| Temporary image retention | Often. Retention fades with varied content anyway, and a slow color cycle is an easy way to give it that. |
| Dead pixel (always black) | No. A pixel that gets no power cannot be switched on by any picture. |
| Permanent OLED burn in | No. Burn in is physical wear. Flashing colors cannot undo it. Use the pixel refresh in your TV or monitor menu and check the warranty. |
| Lines, cracks, pressure marks | No. These are hardware faults. |
If it does not work
- Run it a few more times, with the box right over the pixel. Some stuck pixels respond after several tries, some never do.
- Check the return window and the pixel policy for your screen. A stuck bright pixel is often covered.
- Some guides suggest pressing gently on the stuck pixel through a soft cloth. It can work, but pressing on a panel can also damage it, so try it only on a screen you would be willing to risk, and never with a sharp point.
- For image retention that will not fade, see the burn in test to check whether it is permanent.
Questions
Does a stuck pixel fixer really work?
Sometimes. It works on some stuck pixels and not on others, and there is no way to know in advance. It cannot fix dead pixels. It costs nothing to try for 10 to 30 minutes.
How long should I run it?
Start with 10 to 20 minutes and check the pixel. If nothing changes, try a few more sessions. Running it for many hours is not known to help more.
Can it damage my screen?
It only shows ordinary colors, as any video does. On OLED, avoid leaving any still image on screen for hours; the flashing and cycling modes keep changing, and the box outline hides when the mouse is still.
Can this fix burn in on an OLED?
No tool can fix permanent burn in. It can help temporary image retention fade. For OLED TVs and monitors, the built in pixel refresh is the right tool.
Is the flashing safe?
Flashing light can trigger seizures in people with photosensitive epilepsy. The page warns you before it flashes. Do not use the flashing modes if you or anyone who can see the screen may be affected; the slow cycle and wipe modes do not flash.
