How to use the stuck pixel fixer
The stuck pixel fixer rapidly changes the colour of a small area so a stuck sub-pixel is driven on and off many times a second. Use the dead pixel colour test first to find the pixel and note where it is.
- Choose a mode and timer in the settings card.
- Press Start fixer window, then drag the flashing square over the stuck pixel.
- Let it run for the timer (10-20 minutes is a good start). Press Stop or Esc at any time.
- Recheck the spot with the colour test.
Use Fullscreen fixer if you are not sure where the pixel is.
Photosensitivity warning and gentle mode
Noise and RGB cycle modes flash rapidly. If you or anyone nearby may be sensitive to flashing light, do not use them. Gentle mode slowly drifts through colours with no flashing; it is slower and less likely to work, but much more comfortable.
Why pixels get stuck
A stuck pixel usually has a sub-pixel that stays on because its liquid crystal or transistor is not switching correctly. Repeated switching can sometimes free it. A dead pixel has lost power or has a broken transistor and normally stays black. Learn the difference in dead pixel vs stuck pixel.
Other methods to fix a stuck pixel
- Run the fixer again for longer sessions.
- Turn the screen off for a few hours.
- Gentle pressure with a soft cloth while the screen is off is a known but risky method; it can damage the panel and may affect warranty.
Step-by-step: how to fix a stuck pixel.
When to return a monitor or claim warranty
If the test shows a pixel that never changes, note its colour and position and take a photo with the test colour on screen. Most retailers accept returns within their own return window regardless of pixel policy, so act quickly after purchase. After that window, manufacturer warranty applies, and many brands only replace a panel once a set number or type of defects is reached. Read your exact model’s policy, and see our pixel policy and warranty guide for how the ISO pixel classes work.
Frequently asked questions
Does fixing a stuck pixel online really work?
It can help with stuck pixels, especially new ones, but results vary and nothing is guaranteed. It does not repair dead pixels that get no power.
How long should I run the fixer?
Start with 10-20 minutes. If the pixel changes, run it again. Many people try several sessions before giving up.
Is the flashing safe?
The noise and RGB modes flash quickly and are not suitable for people with photosensitive epilepsy. Use gentle mode, look away while it runs, or don’t use the tool.
Can the fixer damage my screen?
Displaying changing colours is normal use for a screen. Do not press hard on the panel if you also try the pressure method; that can cause damage.
