What Is the Dead Pixel Test?
Sometimes you might randomly notice something that looks like a speck of dirt on your monitor. This can either be what it looks like, or it can be a dead pixel. A dead pixel is a malfunctioned pixel on an LED monitor which is visible in certain colors only.
The dead pixel test checks the monitor for any dead pixels on different colored screens. A dead pixel is a pixel that does not light up. Dead pixels can arise from malfunctioning transistors or manufacturing flaws in the display itself.
Stuck pixels are different from dead pixels, in that they occur when one or more of the three sub-pixels (red, green, and blue) remains turned on so that the pixel displays consistently as a particular color rather than refreshing along with other display content.
With the help of the dead pixel test, you can determine which part of your screen is affected by this problem.
How To Take The Dead Pixel Test?
Using our tool, you can effortlessly test your screen for dead pixels by following the steps given below:
Firstly, you should thoroughly clean your screen with a dry piece of cloth to ensure that there are no dirt spots on it.
Once you've cleaned the screen properly, you have to visit FPS Test and navigate to the dead pixel test page then click on the "Start Monitor Test" button to launch a new page.
Look out for any kind of small dots on the screen which may indicate that the pixels at that point are dead.
Use the arrow keys on your keyboard to change the color of the screen and identify more dead pixels.
Once you have successfully identified the various dead pixels on your screen, just press the ESC key on your keyboard to exit the tool.
What Is Dead, Stuck, and Hot Pixel?
Dead pixels are pixels that do not light up on your monitor. They can be either white or black, but they won't register any color in the display.
Stuck pixels are pixels that have stopped working properly, preventing them from registering any information at all. They may appear as a dark spot or line on your screen, but they won't admit any color or detail when you take a photo.
Hot pixels are pixels that have stopped working properly but haven't yet turned completely black they're still lit up slightly red-hot, which makes them stand out against their surroundings.
Hot pixels often appear as white or yellow spots on your screen, and if left alone they can lead to other problems such as image distortion or blurriness.
Why Does Dead Pixel Occur
The most common reason for a dead pixel is caused by a break in the electrical connection to the backlighting. This can be caused by a dirty or cracked solder joint, or by damage to the video cable.
When this happens, there's no light output from the display panel, which causes a dead pixel.
Other causes of dead pixels include liquid damage and physical damage to components inside your monitor. If you notice that your monitor has any of these symptoms, such as flickering lines or distorted colors, it's time to get it tested.
How To Fix Dead Pixel?
Dead pixels are a common annoyance in modern LCD screens. They're not something to be ashamed of, though: they're just a sign that your LCD screen is in the process of dying.
Not all dead pixels are created equal, and there are lots of different things that can cause them. But there are ways you can fix dead pixels - here's how:
1. Restart Your Device
If you have a dead pixel on your device, the first thing you should do is restart it. A restart will help the device clear its memory and reboot, which can sometimes fix issues with the display.
2. Use Dead Pixel Fixer
The problem with dead pixels is that they're not just a small annoyance: they can cause major headaches.
Dead pixels are caused by a lack of light. so if you've got one, try this trick to get it back to life:
- Open JScreenFix and load up a black browser window.
- Press the green button in the bottom right corner to go full-screen.
- Drag the flashing square over where you think your dead pixel is located, and leave it there for at least 10 minutes (more than enough time to make sure it's functioning properly).
By triggering each pixel's different sub-pixels, it may be possible to massage a stuck pixel back into life!
3. Fix Dead Pixel Manually
If automated tools are not helping you in fixing the dead pixels issue on your desktop, you may consider doing it all by yourself instead. Here's how you can fix dead pixels on your monitor manually.
- Firstly, turn off your monitor and grab a damp cloth.
- Apply a little bit of pressure on the area of your screen where the dead pixel is spotted, but make sure you don't put too much of it as that may worsen the problem.
- Once you apply some pressure, turn on the screen and remove the pressure from the screen.
The method may work for you especially if you have an LCD as applying pressure may spread the liquid equally on the screen.

It's not a big deal, but it can cause problems if you're watching videos or playing games. Dead pixels are usually caused by the display's backlight and are most commonly found in older models of TVs and monitors, where the pixels have become worn out over time.
A dead pixel is a defect, but it's not the one you're thinking of.
A dead pixel is a pixel that does not light up on your screen. It can happen for lots of reasons: the screen might have been dropped and the liquid might have gotten in there and shorted out the pixel, or maybe you just got a new screen and some pixels are still broken from whatever happened to them when they were taken out of production.
The easiest way to spot a dead pixel is to look at the screen when there is nothing on it or if you have no monitor at all! You'll see a series of very bright or dark spots that may look like a pattern or may even look broken up into smaller squares. These are dead pixels.
