Stuck Pixel Fixer
Free online stuck pixel fixer. Place the flashing spot over a stuck red, green or blue pixel, run a timed session and check the result. Works on monitors, laptops, phones and TVs.
What Is A Stuck Pixel Fixer?
A stuck pixel fixer flashes rapidly changing colors over a faulty pixel to force its sub-pixels to switch on and off again. That repeated switching can free a red, green or blue sub-pixel that has become stuck in one state, so it starts following the picture again.
Every pixel is made of three sub-pixels, each controlled by a tiny transistor. A stuck pixel happens when one or more of those sub-pixels stays on all the time, which is why it shows as a bright red, green, blue or mixed dot on a black screen. The circuit still works; it is just not switching properly.
The fixer works by asking that sub-pixel to change state many times a second, cycling through red, green, blue, white and black. In many cases that is enough to get it switching normally again. A dead pixel is different: its transistor has failed, so it stays black no matter what it is asked to show, and no software can bring it back.
Before: Stuck On Red
The red sub-pixel stays lit, so a red dot shows on black and the pixel cannot show other colors properly.
During: Rapid Cycling
The spot flashes red, green, blue, white and black over the pixel, forcing every sub-pixel to switch on and off again and again.
After: Switching Again
If the fix works, the sub-pixel turns off on black like its neighbours and the dot disappears.
How To Fix A Stuck Pixel In 5 Steps
Find the exact pixel first. A small spot right on top of it works better than flashing the whole screen.
Find The Pixel
Run the Dead Pixel Test, turn on Mark and tap the dot to get its x and y.
Place The Spot
Type the x and y into Jump to x, y, or drag the square over the dot.
Pick Speed And Time
Start at 15 flashes per second for 20 minutes. Use Gentle mode if flashing is a concern.
Start And Look Away
Press Start, go full screen and leave it running. Do not watch the flashing.
Check The Result
Use Check pixel to view it on black and white. Repeat a few sessions if it improved.
Which Fixer Mode Should You Use?
All four modes cycle colors through your pixels. They differ in how much of the screen they cover and how intense they are.
Spot
A movable square placed right over the stuck pixel. The most targeted option and the best choice for OLED screens.
Best for one known pixelFull Screen
The whole screen flashes. Useful when there are several stuck pixels or you cannot pin down where they are.
Best for several pixelsPixel Noise
Every pixel gets its own random color each frame, so neighbouring pixels switch independently. A strong all-screen workout.
Best when spot failsGentle
Colors fade smoothly with no flashing. Slower to work, but the safe choice when flashing light is a concern.
Safe, no flashingCan Your Pixel Be Fixed? Stuck, Dead Or Hot
The fixer only helps with one kind of fault. Check how your dot behaves on different colors before you spend time on it.
Is The Stuck Pixel Fixer Safe?
Safe for your screen, but flashing light is not safe for everyone. Here is what to know before you start.
Photosensitive Epilepsy
Web accessibility guidelines (WCAG 2.3.1) warn against content that flashes more than three times a second. The fixer goes far beyond that, so it always asks first. If flashing is a risk, use Gentle mode or do not use the fixer.
Look Away While It Runs
There is no need to watch. Start the session, go full screen and leave the room or look elsewhere. Rapid flashing can cause eye strain and headaches even without epilepsy.
Your Screen Is Fine
The fixer only shows colors, which is exactly what a screen is built to do. It will not damage an LCD panel, and pixels cannot be harmed by being asked to change color.
Go Easy On OLED
OLED pixels age with use, so prefer Spot mode at your normal brightness over flashing the whole screen for hours. Short sessions are enough.
OLED screen testWhat To Do If The Fixer Does Not Work
If several sessions make no difference, the pixel is unlikely to recover with software. These are your next options.
Try Another Mode
If Spot did nothing, run Pixel Noise for one session. Some stuck pixels respond to a different pattern.
Record The Fault
Mark the pixel in the Dead Pixel Test, download the report and take a photo of the dot on black.

Inside the store return window, a swap is usually quickest. After that, check the brand pixel policy and send your report with the claim.

Pressing or rubbing the pixel is widely suggested online, but it can crack the panel, kill neighbouring pixels and void the warranty.
Stuck Pixel Fixer FAQ
Answers to what people ask most before and after trying to fix a stuck pixel.
What is a stuck pixel fixer?
A stuck pixel fixer flashes rapidly changing colors over a stuck pixel to force its sub-pixels to switch on and off again. The repeated switching can free a sub-pixel that has become stuck in one state, so it starts following the picture again.
Does a stuck pixel fixer really work?
It can, but not every time. Pixels that are stuck on one color often respond, while dead pixels never do. Results vary by panel and fault, which is why it is worth running a few sessions before deciding the pixel will not recover.
How long should I run the stuck pixel fixer?
Start with a 10 to 30 minute session, then check the pixel on black and white. If it has improved but is not gone, run another session. If nothing changes after several sessions, the fault is unlikely to clear with software.
Can a stuck pixel fixer fix a dead pixel?
No. A dead pixel stays black because the transistor that drives it has failed, so no amount of flashing can turn it back on. Use the Dead Pixel Test first to find out whether your dot is dead or stuck.
Is the stuck pixel fixer safe for my screen?
Yes. It only shows colors, which is what the screen is designed to do. On OLED screens, use Spot mode at your normal brightness rather than flashing the whole screen for hours, to avoid adding unnecessary wear.
Is it safe for people with epilepsy?
Rapid flashing can trigger seizures in people with photosensitive epilepsy, and accessibility guidelines warn against more than three flashes per second. If that applies to you or anyone watching, use Gentle mode, which fades colors smoothly without flashing, or do not use the fixer.
How do I find where the stuck pixel is?
Run the Dead Pixel Test, turn on Mark and tap the dot. The report gives its exact x and y position. Type those numbers into Jump to x, y here and the fixer square moves straight onto that pixel.
Does the fixer work on phones, laptops and TVs?
Yes, it runs in any modern browser on phones, tablets, laptops, monitors and smart TVs. On iPhone, Safari does not allow true full screen for web pages, so the fixer fills the browser window instead.
What if the stuck pixel fixer does not work?
Check the brand pixel policy and the store return window, and use your test report as evidence. Avoid pressing or rubbing the screen, which is often suggested online but can damage more pixels and may void the warranty.
Can a stuck pixel fix itself?
Sometimes. A stuck pixel can start working again during normal use, but there is no guarantee. Running the fixer is a quicker way to find out whether it is likely to recover.
Ready To Fix Your Stuck Pixel?
Place the spot, start a 20 minute session and check the result.
Flashing Colors Ahead
The fixer flashes bright colors many times a second. Do not continue if you or anyone watching has photosensitive epilepsy or is sensitive to flashing light.
Look away while it runs. Gentle mode fades colors smoothly with no flashing.
