Features
- Rapid random color cycling: exercises stuck pixels with high-frequency red, green, and blue subpixel stimulation, the classic repair method used by screen-fixing tools
- Solid color flashing: pick red, green, blue, white, or black and flash it against black to target a specific stuck subpixel
- Three speed levels: Slow for gentle stimulation, Medium as the default, and Fast for stubborn pixels that need aggressive cycling
- Full-screen mode: the entire monitor cycles colors at once, so multiple stuck pixels are exercised in a single session
- Targeted area mode: drag an 80×80 px fix box over a specific stuck pixel and cycle colors only inside the box
- Touch screen support: drag the fix box with your finger on phones and tablets
- Auto-exit with ESC: press Escape or the exit button to leave full-screen mode at any time
- Safe for your display: color cycling is ordinary pixel activity, no more stressful for the screen than watching a video
- Pairs with the detection flow: find every affected pixel first with Dead Pixel Test, then fix them here in one session
- Multi-spot workflow: move the fix box from pixel to pixel without leaving full-screen mode
- Long-session friendly: the cycling animation never times out, so you can leave it running for the recommended 10–60 minutes
- Works offline after first load
How to Use
- 1Choose a mode: Random cycling is the best starting point for most stuck pixels; Solid flashing lets you target a specific color you can see on the stuck pixel
- 2Pick a speed: start with Medium and switch to Fast if the pixel does not respond after ten minutes
- 3Click Start Fix: the browser enters full-screen mode and color cycling begins immediately
- 4Position the pixel: in full-screen mode the whole screen cycles; in area mode, drag the fix box so it completely covers the stuck pixel
- 5Leave it running: a minimum of 10 minutes is recommended; some pixels need up to an hour of cycling before they recover
- 6Check the result: press ESC to exit full-screen and inspect the pixel from your normal viewing distance on a few different background colors
- 7Repeat if needed: if the pixel is unchanged, run another session with a different color or a faster speed
- 8Fix multiple pixels: in area mode, drag the box to each stuck pixel and let it cycle for a few minutes each, then exit
- 9Use it on phones: the touch interface works the same way: start the fix and drag the box with your finger
- 10Know when to stop: if a black pixel stays black after an hour of cycling, it is a hardware defect, not a stuck pixel, and software cannot repair it
- 11Pair with detection: run Dead Pixel Test first to find all affected pixels and note their positions so you can fix them in order
- 12Consider the warranty: if your screen is still under warranty, report the pixel to the manufacturer instead of relying on software repair
Frequently Asked Questions
How long does stuck pixel repair take?
Leave the color cycling running for at least 10 minutes. Many stuck pixels recover within that window, but some need 30 to 60 minutes of continuous cycling. If a pixel shows no change after an hour, it is unlikely to be repaired by software; it is probably a hardware defect.
Can a black dead pixel be fixed with this tool?
No. A black pixel means the subpixel is physically broken, and no software can revive it. Color cycling only helps stuck pixels, which are pixels stuck on a bright color (red, green, blue, white, or a mix) because their subpixel is stuck in an energized state. For a genuinely dead black pixel, the realistic options are a warranty claim, a screen replacement, or accepting it.
What is the difference between a stuck pixel and a dead pixel?
A stuck pixel is always on or always off and shows a bright spot (usually red, green, blue, or white) because its subpixel is stuck in an energized state; it can sometimes be unstuck with color cycling. A dead pixel is permanently black, caused by a broken transistor or physical damage; it cannot be fixed by software. This tool targets stuck pixels only.
Does this actually work? What is the success rate?
Color cycling has a real but unguaranteed success rate for stuck pixels; reports range from often working within 10–60 minutes to not working at all, depending on the pixel and the screen. We cannot promise a result: if the pixel is a true hardware failure, no software will fix it. The honest recommendation is to try cycling for up to an hour, and if nothing changes, treat it as a hardware issue.
Will the flashing damage my screen?
No. Rapidly cycling colors is ordinary pixel activity; the screen handles thousands of color changes per second during normal video playback. The animation is no more stressful than watching a movie, and there is no burn-in risk from full-screen cycling, since every pixel changes constantly.
How does color cycling fix a stuck pixel?
A stuck pixel's subpixel is stuck in an energized state, holding the pixel on one color. Rapidly alternating pure red, green, and blue light forces the subpixel through its full range of states, which can nudge it out of the stuck position. It is the same idea as gently tapping a stuck mechanical switch; stimulation can release it, but it is not guaranteed.
Can I fix my phone screen with this tool?
Yes. Phone and tablet displays use the same RGB subpixel structure as monitors. Start the fix, then in area mode drag the box over the stuck pixel with your finger. Keep in mind that many phone screens are OLED, where a stuck subpixel behaves slightly differently and the success rate is lower.
Why does my fixed pixel keep coming back?
A pixel that recovers during cycling but reverts later is still marginally stuck; the subpixel was nudged out of position but did not fully recover. Run the fixer again for a longer session (30–60 minutes) and repeat if needed. Some users report permanent recovery after several sessions; others find the pixel recurs and choose to accept it.
Which mode should I use for a red stuck pixel?
For a red pixel, green and blue cycling is the most direct stimulation, because those are the two subpixels that are off. Random cycling covers all subpixel combinations automatically and is the recommended starting point; Solid mode with green or blue flashing is a good follow-up if random cycling does not help.
Does this fix screen burn-in or image retention?
No. Burn-in is permanent damage to OLED or plasma panels, and image retention is caused by different mechanisms than stuck pixels. Color cycling will not remove ghost images or shadow artifacts. If you suspect burn-in, look for a dedicated burn-in test instead of a pixel fixer.
Does the fixer work on a 4K monitor?
Yes. Full-screen mode cycles the entire display regardless of resolution. On a 4K screen the pixels are much smaller, so use the targeted area mode instead: drag the 80×80 fix box precisely over the stuck pixel and sit closer to the screen so you can see it clearly while the cycling runs.
Why is my stuck pixel only visible on some colors?
A pixel stuck on a single subpixel shows different colors depending on the background: for example, a red subpixel that stays energized shows a red dot on black and a cyan dot on white (white minus red). If the pixel looks normal on some backgrounds and wrong on others, it is a stuck subpixel, exactly what this tool targets. Solid mode flashing the two opposite subpixel colors is the most direct stimulation.
How do I know if the pixel is actually fixed?
After exiting the fixer, display several solid backgrounds (white, black, red, green, and blue) over the affected area (Dead Pixel Test is useful for this) and look at the pixel from your normal viewing distance. If it matches the background on every color, it is fixed. If it still shows a bright dot on some colors, keep cycling.
My pixel is stuck on white; can this tool fix it?
A white stuck pixel means all three subpixels are energized, so the fix is the same process: cycling forces each subpixel through its off state. Random mode is the best choice because it alternates every combination. White pixels are sometimes harder to release, so be prepared to run the fixer for the full hour.
Is it safe to leave the fixer running for an hour?
Yes. The animation never times out and the screen handles continuous color changes without issue. You can leave the tab in full-screen and walk away. One note: the fixer only runs while the tab is visible, so do not switch to another window or lock the screen during the session.
What should I do if the fixer does not work?
After an hour of cycling with no change, the pixel is almost certainly a hardware defect. Your realistic options are: claim the warranty if the screen is still covered (this is the strongest option; manufacturers usually accept pixel defect claims within policy limits), contact the manufacturer for repair, or accept the pixel. Do not press or rub the screen; physical force can make the defect worse.
