Stuck pixel fixer
Drag the patch over the stuck pixel, press Start, and let the flashing noise run for about 10 minutes, then check the pixel again.
Stuck pixel fixer workspace
How to use
4 short steps.
Confirm the pixel is stuck, not dead
Run the dead pixel test first. The fixer only helps a point that stays lit in one color; it cannot help a point that stays black.
Drag the patch over the pixel
Move the patch with the mouse or the arrow keys and drag its corner to resize it. It only needs to cover the pixel.
Press Start and leave it running
Start fills the screen with black and begins the noise. Leave it for 10 minutes; some people run it for up to an hour.
Stop and check the pixel
Press Escape or Stop, then open the dead pixel test and look at the same spot on black, white, red, green, and blue.
What the result means
Match what you see to one of these.
If the pixel now changes with the field, it recovered
If the point is gone on every color, the stuck subpixel has freed up. Check again the next day, because a stuck pixel can come back.
If the pixel is still stuck after an hour, stop
If the point still shows one color after 30 to 60 minutes, more time is unlikely to help. Contact the manufacturer or check the pixel policy for a replacement.
Troubleshooting
If the test fails, try these in order.
Make sure the patch covers the pixel
Go full screen, drag the patch over the exact spot, and make it larger if you are unsure. Run it again.
Use the fast speed
The fast setting changes the noise every frame, which is the exercise other tools run. Only use slow if flashing bothers you. Run it again for 10 minutes.
Try a gentle press with the screen off
Some people report success pressing lightly on the spot through a soft cloth with the display off. Do this at your own risk, then check the pixel on the dead pixel test.
Check it again on the dead pixel test
Static colors show the pixel more clearly than the moving patch. Compare the same spot on black, white, red, green, and blue.
What this test can't tell you
Where a browser check stops.
- Flashing a stuck pixel is an unproven exercise. It sometimes helps a stuck subpixel and never helps a dead one, and the page cannot see whether anything changed.
- The patch flickers rapidly in a small area. Do not run it if flashing light affects you; the slow setting changes once a second instead.
FAQ
Common questions about this test.
Can you actually fix a stuck pixel?
Sometimes. A stuck subpixel that is receiving power but not switching can free up after minutes of rapid color changes. Reports vary, and there is no guarantee for any one screen.
Is a stuck pixel permanent?
Not always. Stuck pixels sometimes clear on their own or after a fixer run, and sometimes return later. A dead pixel that stays black is permanent.
Can a dead pixel fixer fix a dead pixel?
No. A dead pixel gets no power, so no pattern on the screen can change it. Fixers only work on stuck pixels that are lit in one color.
How long should I run the stuck pixel fixer?
Run it for 10 minutes first, then check the pixel on the dead pixel test. If the pixel is still stuck, you can try up to an hour, but longer than that rarely helps.
