When a stuck pixel fixer is worth trying
Use the fixer after one small point still appears lit on a fixed color, such as red, green, blue, cyan, magenta, yellow, or white. That behavior may be a stuck pixel or stuck subpixel.
Do not use it as a guaranteed repair. A browser stuck pixel fixer can attempt mitigation by cycling colors over the affected area, but it cannot prove the cause or guarantee recovery.
What color cycling may help
Color cycling rapidly changes the color shown over the affected area. That may help some stuck pixels or stuck subpixels change state again.
The best candidate is a single colored or bright dot that still emits light. A black dot that stays black on bright screens is usually a poor candidate for software mitigation.
Should you try the stuck pixel fixer?
| What you see | Fixer may be worth trying? | Why | Better next step if not |
|---|---|---|---|
| Red, green, blue, cyan, magenta, yellow, or white dot that stays the same | Yes | It looks like stuck-pixel or stuck-subpixel behavior. | Run a bounded session and retest with the Pixel Test. |
| Tiny black dot on white or bright screens | Usually no | A black dot may be a dead or dark pixel, not a stuck-on pixel. | Run the Pixel Test, then document the result. |
| Bright white dot on a black screen | Maybe | A hot or bright pixel may behave like a stuck-on subpixel. | Use a short session only, then retest. |
| Dot only visible on one test color | Maybe | One color component may be affected, or the mark may not be a pixel defect. | Classify it with the Pixel Test first. |
| Dot changes or disappears after color cycling | Yes, cautiously | Visible change suggests the pixel responded. | Stop once the result is stable and retest later. |
| Faint ghost image or taskbar shadow | No | Burn-in or image retention is not a single stuck pixel. | Use the Burn-In Test. |
| Uneven glow near edges or corners | No | Edge glow, IPS glow, and backlight bleed are not stuck pixels. | Use the Backlight Bleed Test. |
| Cloudy pressure mark or bruised area | No | Color cycling cannot undo panel pressure damage. | Document the issue before support or resale. |
| Vertical or horizontal display line | No | A line may involve the panel, cable, driver, or display path. | Retest with another source, then contact device support if it persists. |
| Cracked glass or impact damage | No | Physical damage is not a stuck-pixel state. | Use repair or support guidance. |
| Issue visible only in one app, browser, video, or input source | No | The source may be creating the artifact. | Retest with another app, browser, video, or input. |
What a stuck pixel fixer cannot repair
A stuck pixel fixer cannot repair dead pixels, cracked glass, pressure damage, burn-in, backlight bleed, display lines, failing panels, or severe physical damage. It also cannot prove whether a manufacturer will cover the issue.
Use the result as a mitigation attempt, not a warranty decision.
| Issue | Why a fixer may not help | Better next step |
|---|---|---|
| Dead pixel | The pixel may not be lighting correctly. | Run the Pixel Test and document the result. |
| Hot or bright pixel | It may fall under a pixel policy instead of recovering through color cycling. | Try one short session, then document it. |
| Burn-in or image retention | A retained image or shadow is not a single stuck pixel. | Use the Burn-In Test or Burn-In Fixer. |
| Backlight bleed | Edge or corner glow is a uniformity issue, not a stuck pixel. | Use the Backlight Bleed Test. |
| Pressure mark or physical damage | Color cycling cannot undo panel damage. | Document the issue and compare support or repair options. |
| Display line | A line may involve panel electronics, a cable, a driver, or the display path. | Retest with another source and contact support if it persists. |
| Cracked glass | A physical break is not a pixel state. | Use repair or support guidance. |
| App, browser, video, or input-source artifact | The issue may not be in the display panel. | Retest with another source. |
If it is a single dot, run the Pixel Test first. If it looks like a retained image or static UI shadow, use the Burn-In Test or Burn-In Fixer. If the issue is edge glow, run the Backlight Bleed Test. If it looks like pressure damage, document it before support or resale.
Before you run the fixer
Clean the screen
Dust, a chip, a reflection, or a mark on the glass can look like a bad pixel.
Classify the dot first
Use the Pixel Test if you are not sure whether the issue is dead, stuck, hot, burn-in, backlight bleed, a pressure mark, a display line, or a source artifact.
Use reasonable brightness
Very high brightness and long sessions can add heat, especially on OLED, AMOLED, phones, laptops, and battery-powered devices.
Keep the device ventilated
Stop if the screen or device gets unusually hot.
Do not stare at the flashing pattern
Start the session, look away, keep the room lit, and stop immediately if the flashing causes discomfort.
Do not press hard on the screen
Pressure can damage some displays. Do not rub or press unless official device guidance says to do so.
How long to try it and when to stop
Try reasonable sessions rather than leaving the fixer running indefinitely. Start short, retest, and extend only if the dot is still a plausible stuck-pixel candidate and the device stays cool.
| Retest result | What it suggests | What to do |
|---|---|---|
| The dot now changes normally | The stuck state may have cleared. | Stop and check it again during normal use. |
| The dot is dimmer, intermittent, or partly changed | The fixer may be having some effect. | Run one more short session, then retest. |
| The dot stays colored or bright after repeated attempts | Recovery response is weak. | Stop the planned attempts and document the result. |
| The dot now stays black | It no longer fits stuck-pixel behavior. | Run the Pixel Test and document it as a possible dead pixel. |
| The screen gets hot, the device becomes unstable, or flashing causes discomfort | The attempt is no longer worth continuing. | Stop immediately. |
| The issue spreads into a line, cluster, haze, or shadow | It is probably not one stuck pixel. | Use the right diagnostic page or contact support. |
Stuck pixel, dead pixel, hot pixel, or another screen issue?
| Type | What it looks like | Can this fixer usually help? | Best next step |
|---|---|---|---|
| Stuck pixel or stuck subpixel | One tiny point stays red, green, blue, cyan, magenta, yellow, or another fixed color. | Maybe. This is the main use case. | Run a bounded session and retest. |
| Dead or dark pixel | One tiny point stays black on white or bright screens. | Usually no. | Run the Pixel Test and document it. |
| Hot or bright pixel | A tiny white or bright point stands out on black screens. | Maybe, but not guaranteed. | Try one short session, then check manufacturer policy if it remains. |
| Burn-in or image retention | A faint shadow, logo, keyboard, or taskbar shape remains visible. | No. | Use the Burn-In Test. |
| Backlight bleed or uniformity issue | Glow, haze, or uneven brightness near edges or corners. | No. | Use the Backlight Bleed Test. |
| Pressure mark or damage | Cloudy patch, bruise, line, crack, or distorted area. | No. | Document the damage and compare support options. |
| Source artifact | The issue appears only in one app, browser, video, cable, or input. | No. | Retest with another source. |
Test first if you are not sure what the dot is
Use the Pixel Test first if you are not sure whether the issue is a dead pixel, stuck pixel, hot pixel, burn-in, backlight bleed, pressure mark, display line, or app/browser artifact. Use the fixer only after the dot looks like stuck-pixel or stuck-subpixel behavior. The test identifies and documents the issue. This page attempts stuck-pixel mitigation.
Save proof before repair, warranty, resale, or trade-in
If the pixel does not change, document the issue for warranty or support. Take photos on black, white, red, green, and blue screens, note whether the defect changed after the fixer, record the device model, and check the manufacturer’s pixel policy or return window before you compare repair and replacement options.

Stuck Pixel Fixer FAQ
Can a stuck pixel fixer actually fix a stuck pixel?
It may help some stuck pixels or stuck subpixels, but it is not guaranteed. If the dot does not change after reasonable attempts, stop and document it.
Can dead pixels be fixed?
A dead pixel usually appears black because it is not lighting correctly. This fixer is not for confirmed dead pixels.
How do I know if a pixel is stuck or dead?
A stuck pixel usually stays one color or bright white. A dead pixel usually stays black on bright or color screens. Run the Pixel Test first if you are unsure.
Is it safe to run a stuck pixel fixer?
Use it cautiously. Do not use it if flashing lights may affect you, and stop for discomfort, heat, or device instability.
How long should I run the stuck pixel fixer?
Start with a short session and retest. Extend only if the dot is still a plausible stuck-pixel candidate and the device stays cool.
When should I stop using the fixer?
Stop if the pixel does not change after repeated attempts, turns black, spreads into a line or cluster, or the screen gets hot.
Does flashing colors work on OLED screens?
It may help some stuck-looking dots, but OLED and AMOLED screens need more caution around heat, brightness, and long sessions.
Does flashing colors work on LCD screens?
It may help some stuck subpixels on LCD screens. It will not repair every defect, and manufacturer pixel policies still matter.
Can the fixer repair a bright pixel?
Maybe. A bright or hot-looking pixel may behave like a stuck-on subpixel, but it may also be a defect that needs documentation.
Can the fixer repair burn-in?
No. Burn-in and image retention are not single stuck pixels. Use the Burn-In Test or Burn-In Fixer instead.
Can the fixer repair backlight bleed?
No. Backlight bleed and corner glow are screen uniformity issues, not stuck pixels.
Should I run a pixel test first?
Yes, if the dot is unclassified. The Pixel Test is the better place to identify whether the issue is dead, stuck, hot, or something else.
What should I do before warranty or repair support?
Save photos on multiple color screens, note whether the pixel changed after the fixer, record the device model, and check the manufacturer’s pixel policy.
