Stuck Pixel Fixer
Flash fast changing colors over a stuck pixel to try to free it. Place a small box over the pixel or flash the whole screen, and let the timer stop it for you.
Flashing lights warning. The fixer flashes bright colors many times per second. Do not use it if you have photosensitive epilepsy or are sensitive to flashing lights, and do not look at the screen while it runs.
Best when you know where the stuck pixel is. Drag the box over it.
The timer pauses if you switch to another tab.
Press Esc or Stop to end early.
What is a stuck pixel?
Each pixel has a red, a green, and a blue part. A stuck pixel has one or more of those parts stuck on, so it shows the same color (often red, green, blue, or white) no matter what is on screen. It is easiest to see on a black background.
This tool switches the pixel through red, green, blue, white, and black on every screen refresh. That rapid switching can sometimes get a stuck part working normally again.

How to fix a stuck pixel
- 1
Find the stuck pixel
Run the dead pixel test on a black screen and note where the colored or bright dot is.
- 2
Pick what to flash and for how long
Choose Small box if you know where the pixel is, or Whole screen if there are several or you cannot find it. Then pick 10, 20, or 30 minutes.
- 3
Start the fixer and place the box
Click Start stuck pixel fixer. The page goes full screen. Drag the flashing box over the stuck pixel, or tap the spot. Arrow keys move the box 1 pixel at a time, or 10 with Shift.
- 4
Leave it running, then check again
Look away while it flashes. When the timer ends, check the pixel again on black. If it is still stuck, run the fixer a few more times.
Stuck pixel fixer options
- What to flash
- Small box flashes only the area you place it over, so the rest of the screen stays black. Whole screen flashes everything, which helps with several stuck pixels or one you cannot find. The whole screen is much brighter, so it is harder to look away from.
- Box size
- Use the minus and plus buttons in the fixer (or the - and + keys) to pick 50, 100, 150, 200, or 300 pixels. A larger box is easier to place over the pixel. A smaller one flashes less of the screen.
- Stop after
- The fixer stops by itself and leaves full screen after 10, 20, or 30 minutes, or runs until you press Esc or Stop. Time only counts while the fixer is on screen.
What a stuck pixel fixer can and cannot fix
Flashing colors only helps a pixel that still gets power but is stuck in one state. Check what you have before you spend time on it:
- ·Stuck pixel (worth trying). A dot that stays red, green, blue, or a mix such as cyan or yellow.
- ·Hot or bright pixel (worth trying). A dot that stays white. All three parts are stuck on.
- ·Dead pixel (cannot fix). A dot that stays black on every color. It gets no power, so flashing cannot reach it.
- ·Lines across the screen (cannot fix). A full row or column of wrong pixels usually points to a loose cable or a fault in the panel.
- ·OLED burn-in (cannot fix). A faint, lasting ghost of an image, such as a taskbar or logo. This is wear on the pixels, not a stuck pixel.
Not sure which one you have? Run the dead pixel test and compare the dot on black and on white.
Using the stuck pixel fixer safely
- ·Do not use it if you or anyone nearby has photosensitive epilepsy or is sensitive to flashing lights.
- ·Place the box, then look away or leave the room until the timer ends.
- ·Do not press on the pixel or tap the screen to help it along. Pressing on an LCD can damage it and make more pixels fail.
Who uses a stuck pixel fixer
- ·People with a stuck pixel on a new screen. Try a quick fix before deciding whether to return the monitor, laptop, or phone.
- ·Owners of older screens. A pixel that got stuck after years of use may still come back, and the screen is often out of warranty anyway.
- ·Buyers of used devices. Try to clear a stuck pixel found after buying.
Frequently asked questions
- Does a stuck pixel fixer really work?
- Sometimes. Flashing colors makes the stuck pixel switch on and off very quickly, over and over, and that can free a red, green, or blue part that is stuck. It does not always work, and there is no way to know in advance. It costs nothing to try before you return or repair the screen.
- How long should I run the stuck pixel fixer?
- Start with 10 to 20 minutes, then check the pixel. If it has not changed, run it a few more times. If several runs make no difference, the pixel probably will not recover and it is time to contact the seller or manufacturer.
- Can this fix a dead pixel?
- No. A dead pixel gets no power, so it stays black and flashing colors cannot reach it. Tools called dead pixel fixers can only help with stuck pixels, which stay lit in one color. Use the dead pixel test to find out which kind you have.
- How do I know if my pixel is stuck or dead?
- Show a black screen and then a white screen. A stuck pixel stays lit (red, green, blue, or white) and is easiest to see on black. A dead pixel stays black and is easiest to see on white. Only a stuck pixel can be fixed this way.
- Is the stuck pixel fixer safe for my screen?
- Yes. It only switches pixels between ordinary colors, the same work a screen does when it plays fast-moving video. It does not press on or heat the screen. The safety concern is for people, not screens: the flashing can trigger seizures in people with photosensitive epilepsy.
- Why does the box flash so fast?
- It changes color on every screen refresh, which is as fast as your screen can switch. That is 60 times a second on a 60 Hz screen and faster on a high refresh rate screen. Fast switching gives the stuck pixel the most chances to come loose.
- Does it work on phones, tablets, and TVs?
- Yes. It runs in any modern browser. On iPhone, browsers do not allow full screen for web pages, so the fixer fills the browser window instead. The small box still works anywhere inside it.
- Can I use my computer while the fixer runs?
- Not on the same screen, since the fixer covers it. If you switch to another tab or window, the browser pauses the flashing and the timer stops until you come back.
- Is this stuck pixel fixer free?
- Yes. There is no signup and nothing to install. It runs entirely in your browser.
