Stuck Pixel Fixer
Found a stuck pixel? Drag this fast color-noise box over the spot and let it run to coax the frozen subpixel back. Free, in your browser, and no install.
Go full screen, drag the noise box onto the stuck pixel, and press Start. Give it ten to thirty minutes. Stuck pixels sometimes free up. A dead one almost never does.
Stuck or dead?
Only a stuck pixel is fixable. Tell the two apart before you spend time on it.
Stuck
Glows one color on a black screen. Still powered, so it is fixable.
Dead
Stays black on every color. Draws no power, so it will not come back.
See it in action
The noise box drags onto each stuck pixel and drives its subpixel through every color many times a second until it clears.
How to use
- Confirm it is stuck, not dead. A stuck pixel glows one color on a black screen. A dead pixel stays black on every fill and will not respond to this. Run the dead pixel test first if you are not sure which one you have.
- Go full screen. Press Full screen so the noise box can reach a pixel anywhere on the panel, not only inside the small preview. The controls stay on screen for you.
- Cover the pixel. Drag the noise box until the stuck pixel sits inside it. Drop the box to a smaller size if the pixel sits near a screen edge.
- Run it and wait. Press Start and leave the fast color noise running for at least ten minutes. Most pixels that come back do so inside half an hour.
- Check, then repeat or stop. Look at the spot on a black screen. If the dot is gone, you are done. If not, run it again. After about an hour with no change, the pixel most likely will not recover.
Why test this
A stuck pixel is a single dot frozen on one color while the screen changes around it. One subpixel is jammed on instead of switching with the image. Unlike a dead pixel, it still draws power, so there's a real chance of jolting it loose. This fixer floods a small box with fast random color. You drag it right over the pixel, and the noise drives that subpixel across its whole range many times a second. Catch it early. A pixel that just got stuck comes loose easier than one left jammed for months. Run it on a new monitor, laptop, or phone while the return window is still open. Try the free fix before you fall back on the warranty claim. Found the pixel with our dead pixel test? Drag this box over it next.
What the results mean
Keep an eye on the spot under the box as it runs. A win is obvious: the dot starts taking the colors again and blends back in. Most pixels that come back do so in the first half hour, so give it a proper run before you judge it. Color plays a part. A stuck red pixel tends to free up sooner than a stubborn blue one, and a pixel that jammed days ago beats one frozen for a year. If a half hour of noise does nothing, try another pass or two, then let it go. A dot that never leaves black was never stuck, it's dead, draws no power, and needs a panel repair or a warranty claim. Check your maker's dead pixel threshold before you decide the screen goes back.
FAQ
- Does a stuck pixel fixer actually work?
- Sometimes. Flooding a stuck pixel with fast random color frees it often enough to be worth the time, and it works best on one that only just got stuck. Red tends to recover more easily than blue. A pixel that's truly dead, black no matter what, almost never comes back.
- How long should I run it?
- Ten to thirty minutes is the sweet spot, and most pixels that recover do so inside half an hour. If nothing changes after that, run it once or twice more before you give up.
- Is the fast flashing safe?
- The noise box stays small and its colors are random pixel by pixel, so the average brightness holds steady with no big screen-wide flash. Even so, skip it if you have photosensitive epilepsy, and keep the box small rather than maxed out.
- What is the difference between a stuck and a dead pixel?
- A stuck pixel is frozen on one color, usually red, green, or blue, and still gets power, so it has a shot at recovery. A dead pixel gets no power and stays black on every color. This tool can only help the stuck kind.
- Can I use it on an OLED screen or a phone?
- Yes. The color noise is safe on OLED and phone panels, and stuck pixels are common on both. Don't press or rub an OLED to fix a pixel though, since that can cause permanent damage.
