Your computer’s screen or monitor is made up of millions of carefully programmed tiny light sources known as pixels that create the images you see. Within the pixels are subpixels that emit RGB (red, green, and blue) colors that, when combined, emit pure white light, while other colors are emitted by varying the levels of each of the three colors.
Pixel stuck occurs when one of these subpixels gets stuck in a single color – red, green, or blue – and appears on your monitor as a steady bright dot.
Stuck pixels are different from dead pixels, which remain black all the time regardless of the image on your monitor, because they are not exposed to light. They are also quite difficult to fix and sometimes you need to replace your monitor.
Fortunately, you can use Dead Pixel Tests to diagnose and fix monitor problems, to fix stuck pixels through a number of techniques and software.
What causes pixelated stalls?
Defective or stuck pixels have bothered monitors ever since LCDs (liquid crystal displays) were introduced.
Stuck pixels are stubborn little squares that keep the same color all the time, but are not always constant. They are caused by hardware problems, usually due to manufacturing defects such as assembly errors, or an always-on transistor that can affect a pixel or one of its three subpixels.

For example, if something in the pixel was not properly fabricated on top of the glass substrate, resulting in a malfunction in the electrical circuit. However, in most cases, pixel stuck does not necessarily mean that the entire pixel is damaged. It can only be one or a few subpixels that form color combinations in a pixel.
Before returning to the store for a replacement or repair, there are several things you can do to fix the problem. We are going to show you how to fix dead pixels as well as how to perform a dead pixels test to fix a stuck pixel on your monitor.
Difference between Stuck Pixel and Dead Pixel
A stuck pixel is displayed in one of three colors of its subpixels: red, green, or blue. If you notice an odd pixel in one of these colors, then the pixel is stuck.
Dead pixels, on the other hand, look like little black rectangles because their subpixels are completely disabled due to a broken transistor, which means the pixels are not powered for them to light up.
However, in some cases, a black pixel might get stuck, not necessarily dead. The main difference is that a stuck pixel is always on, and a dead pixel just doesn’t turn on anymore. Unlike dead pixels, which are rarely recovered, stuck pixels are simply stable and can respond to various measures.
If you see a white or colored pixel, try one of the methods listed below to fix it.
How to fix a stuck pixel on your screen
1. Please wait.
2. Perform a dead pixel test or check.
3. Use pressure and heat.
4. Use third-party software to flash the pixel.
5. Replace monitor.
A stuck pixel is easier to fix than a dead one because it still has a power source and you can return it to normal. However, not all methods are guaranteed to work because it ultimately depends on what is wrong with the pixel.
If none of this works, replace your monitor as a last resort.
Wait
Stuck pixels can peel off after a few hours. Some may take days or weeks, sometimes years, but you’re not going to wait that long for things to be settled.
If you don’t have the patience to wait, try the other methods below.
Run Dead Pixel Test
The Dead Pixel Test involves running the monitor in full screen mode using the Primary Color Picker or grayscale to identify a stuck pixel.
To do this, wipe the screen with a soft cloth, and then open the “Dead Pixel Test” site in your browser. Switch to full screen mode to take a close look at all test screens.
Use pressure and heat
Use pressure and heat
These are manual methods for removing stuck pixels through a combination of pressure and heat.
Before you start, turn off your monitor and use a damp cloth to apply pressure to the area where the pixel is stuck without touching other areas, as this may increase the number of pixelated pixels.
As you apply pressure, turn on the computer and screen, release the pressure, and check if the stuck pixel is gone. Usually, liquid in one or more subpixels passes through them, creating different colors and evenly distributing them.
The heating method is to apply a heated cloth to the stuck pixel for a few seconds and then turn off the monitor for up to 48 hours to allow the pixel to consume excess power and turn off.
Use third party Pixel flashing software
Using third-party software to flash Pixel
Stuck pixels are hardware issues, but you can get a program that can act as a dead pixel fixer to detach the pixel.
You can launch a stuck pixel and other pixels around it using software by cyclically changing the colors on the screen. The program constantly asks the pixel to change its color.
There are several options available, but you can try using software like JScreenFix, PixelHealer, or UndeadPixel to unpin the pixel.
JScreenFix can help you fix a stuck pixel, but it won’t help you find it. To use the software, open the site in a browser and click the blue Launch JScreenFix icon. A black square with many flashing pixels will appear in the browser window.
You can launch the window in full screen mode by clicking the green button in the lower right corner of the screen, drag the square to the area where the stuck pixel is, and leave it there for 10 minutes.
UndeadPixel is a Windows Dead Pixel Checker tool that can help you find a stuck pixel with its locator, which cycles through multiple colors on your screen. A blinking dot will appear, which you can drag onto the screen over the dead pixel and let it run for several hours.
You can also run an online monitor test to identify stuck pixels when checking the quality of your monitor. This test offers three modes in which you can check your screen for stuck pixels.
Replace monitor
This is the last resort for fixing a stuck pixel if really needed. Most manufacturers offer repair or replacement warranties, so check your device’s warranty before taking this step.
