The Stuck Pixel Fixer is a bounded browser-based attempt for one fixed colored, white, or unusually bright point. It cycles colors over a selected area and then lets you retest the same point. It cannot repair confirmed dead pixels, lines, patches, burn-in, backlight bleed, or physical damage. If you are unsure what the point is, run the Pixel Test first.
Before you start: is this point a reasonable fixer candidate?
The fixer is most appropriate when one small point remains colored, white, or unusually bright in the same location across several test fields. Classify the point first, rule out a surface or source artifact, and check the display’s policy before attempting repair.

| What you see | Try this tool? | Next step |
|---|---|---|
| One fixed colored, white, or bright point | Possibly | Check the display policy, then try one bounded session. |
| A black or dark point that stays dark | No | Run the Pixel Test and document it for support. |
| A line, patch, crack, haze, edge glow, or retained image | No | Use the relevant diagnostic or support route. |
| You are unsure whether the point is fixed | Not yet | Run the Pixel Test first. |
| The mark appears only in one app, video, cable, or input | No | Test another source or input before using the fixer. |
Check the display policy first
If the display is new, returnable, or covered, document the pixel defect for warranty or support before experimenting. Policies can differ by model, region, defect type, and number of affected pixels.
How to run one bounded stuck-pixel fixer session
Confirm the point first
Run the Pixel Test and use the fixer only for one fixed colored, white, or bright point.
Target the point
Use Precision Window for a single-point issue and place it over the affected point. Use fullscreen only when the point cannot be isolated.
Start one bounded session
Start with the shortest available session. The timer sets the length of your attempt; it does not predict whether the pixel will recover.
Look away when the pattern runs
Do not stare at the flashing pattern. Stop immediately if it causes discomfort, dizziness, or visual strain. Stop as well if the device becomes unexpectedly hot or unstable.
Retest the same point
Exit the pattern completely, then check the same point on black, white, red, green, and blue before deciding whether to stop or document it.
How long should you try a stuck pixel fixer?
Start with one short session and retest before extending anything. The 10- and 30-minute options are preset attempt lengths, not proven recovery thresholds. If the point is unchanged after a complete attempt, do not continue flashing indefinitely or run the tool overnight.
What should you do after the fixer session?
The tool cannot determine whether the panel repaired itself. Retest the same point across the core colors and use the result to decide whether to stop, allow one limited retry, or document the issue.
Retest the same point
Swipe sideways to compare columns.Scroll table to view all columns.
| Retest result | What it suggests | What to do |
|---|---|---|
| No longer visible | The point may have returned to normal. | Stop the fixer and monitor. |
| Dimmer or visibly changed | The appearance responded, but the issue remains. | Allow at most one limited retry. |
| Unchanged | There is no observable response. | Stop, document the issue, and check support options. |
| Now dark or black | The symptom changed but is not confirmed repaired. | Run the Pixel Test again. |
| Became a line or patch | It is no longer a simple point defect. | Stop and use the relevant support route. |
What the browser is doing
The browser repeatedly displays different color values over the selected area. This gives the point a changing sequence of display states, but it cannot inspect the panel or prove why the pixel is stuck.
What the Stuck Pixel Fixer can and cannot repair
What may be worth one bounded attempt
One fixed colored, white, or unusually bright point may be worth one bounded browser-based attempt after classification, surface inspection, and policy review. Its appearance does not confirm the internal cause or guarantee recovery.
Problems this fixer is not designed to repair
- Confirmed dead or black pixels
- Burn-in or permanent image retention
- Backlight bleed
- Lines, cracks, pressure marks, or broad patches
- Software or source artifacts
- Internal electrical or panel faults
LCD, OLED, and manufacturer pixel-care routines
What the browser session means
The browser can display the pattern on a monitor, laptop, phone, tablet, or TV using an LCD or OLED panel. That means the session can run; it does not prove that the same type of defect can be recovered on every panel. ScreenDetect cannot guarantee recovery on any display technology.
Manufacturer Pixel Refresh is different
Pixel Refresh, Pixel Cleaning, and Panel Care are model-specific routines supplied by some display makers. They are not equivalent to ScreenDetect’s browser animation. If your display has one, follow the manufacturer’s instructions for that model.
Avoid pressure, heat, and improvised physical methods
Don’t press, rub, tap, heat, freeze, or insert objects into the screen or its openings to force a pixel change. These methods can add physical or coating damage and may complicate a return or warranty claim.
If the pixel does not change
Document the defect
Photograph the point on useful solid colors, record the display model and purchase timing, and keep the original images. Avoid aggressive digital enhancement because it can introduce artifacts. If you need a formal record, document the pixel defect for warranty or support.
Check support or replacement options
Review the manufacturer’s policy and contact the seller or manufacturer if the display is covered. If the issue remains unresolved, compare repair versus replacement options. Do not continue flashing indefinitely.
If this is not one pixel
Use the Fixer only when one colored or bright point stays in the same place. Choose a different ScreenDetect path when the symptom is a dead point, retained image, edge glow, line, patch, or unresolved defect.
Choose the path that matches the problem
Swipe sideways to compare columns.Scroll table to view all columns.
| Tool path | Use it when | Why |
|---|---|---|
| Pixel Test | You are unsure what the point is. | It helps classify the defect before repair. |
| Burn-In Test or Fixer | You see an image-shaped shadow or retained pattern. | That is not a single stuck pixel. |
| Backlight Bleed Test | You see glow near an edge or corner. | Edge light leakage needs a different check. |
| Support or warranty path | The display is new, covered, or unchanged. | Policy and inspection may matter more than another session. |

Stuck Pixel Fixer FAQ
Is the Stuck Pixel Fixer free?
Yes. It runs in your browser without a download, account, or sign-up.
Can it fix a dead pixel?
A confirmed dark or dead pixel is not a good candidate for this browser repair attempt. Use the Pixel Test to classify it, then document it for the applicable support or pixel policy.
Does it work on OLED screens?
The browser can display the pattern on OLED screens, but that does not guarantee recovery. Follow any manufacturer-provided Pixel Refresh or Panel Care instructions for your model.
When should I stop using it?
Stop for discomfort, unexpected heat, device instability, a broader line or patch, or no observable change after a bounded attempt. Retest and document the issue instead of flashing indefinitely.
What should I do if the pixel does not change?
Photograph the point on useful solid colors, record the display model and purchase timing, check the manufacturer’s policy, and contact the seller or manufacturer if the display is covered.
