Dead Pixel Test | Test your screen for bad pixels

What is the Dead Pixel Test?

The dead pixel test is a way to determine if your screen contains any dead pixels that can cause irritation while playing games or doing aim training.

What is a Pixel?

A pixel is the smallest unit of a digital image or graphic. Pixels are usually round and small, and are arranged in a grid on your screen. Each pixel has a certain color, which is determined by the amount of red, green, and blue light that it emits.

What is a Dead Pixel?

It is a pixel on your screen that is not displaying any color. In a general sense, it will always be like a black dot on your screen. This can be caused by a number of things, such as a loose connection or simply a bad pixel.

What do you mean by a Stuck Pixel?

A stuck pixel is a pixel that is stuck on one color and won’t change. Any physical damage to your screen can result in a stuck pixel.

How do I take the Dead Pixels Test?

Simply follow these steps to take the pixel test :

Step 1: Navigate to the screen and select a color of your choice.

Step 2: Click on the start button displayed in green.

Step 3: After clicking ,the test will start. Take the test in full-screen mode to carefully look for any stuck or dead pixel.

Step 4: You can use your mouse click or the keyboard arrows to change the color of your screen. If you find any pixel that is not displaying anything, then you have a dead pixel.

Repeat the process until you can spot all the bad pixels on your screen.

What can cause Dead Pixels?

There are a few things that can lead to bad pixels which are :

Manufacturing defect

A manufacturing defect is one of the most common reasons for bad pixels. While producing a display, mistakes may occur that might result in some transistors on your screen not functioning. After producing each screen, many firms conduct rigorous testing of partial sub pixel defects to ensure that they function properly. However, some checks are insufficient to detect bad pixels, particularly if the display has a large number of pixels.

Physical screen damage

When your phone or computer hits the ground, the impact can cause some of the pixels to be damaged. The screen may continue to operate properly, but sections of the screen might not show any information. If there are only a few defective pixels, you may not even notice them.

Burn-in Issue

This is usually not a problem with Liquid Crystal Display (LCD) screens, but it can be an issue with OLED screens. If you leave a static image on your screen for too long, it might cause that image to become “burned-in” or permanently imprinted onto your display. This process can damage pixels and lead to a bad pixel.

Electrical Damage

If there is an electrical problem with your screen, it could result in some of the pixels not working. This type of damage is usually not covered by a warranty.

Liquid Damage

The display is one of the most prone components that may easily be damaged if it gets splashes of water or is immersed in water. This is because when transistors that power up your display, fail immediately when they come into direct contact with water. Get yourself a waterproof device if your job or home environment requires you to get in contact with water more often. Water damage is usually not covered by a warranty.

Product Tenure

Displays also age with time, just like any other electrical gadget. With time, some pixels on your display gradually degrade. This takes a lot of time to happen unless you use your device carelessly. Most modern electronics can be used for more than ten years without problems with the display pixels appearing. Hence, getting bad pixels is quite rare.

3 ways to avoid getting dead pixels

There are a few things you can do to prevent it :

Be careful with your screen.

Be careful not to drop your phone or laptop, and be careful not to hit it against something hard. If you do drop it or hit it, immediately check you screen for any major damages.

Take care of your screen.

Clean your screen regularly with a soft cloth. Do not use any harsh chemicals or cleaners on your screen. Also, do not use static wallpapers for your screen as they can cause burn-in issues.

Take a pixel warranty.

Some companies offer a warranty that will replace your screen if you get a certain number of bad pixels. This can be a good option if you are worried about your screen.


Q1. I think I have a dead pixel. What should I do?

Ans: If you think you have a dead pixel, the best thing to do is to start testing your screen for a bad pixel. This will help you determine if you actually have a faulty display or not.

Q2. Can you actually fix dead pixels?

Ans: You can try the JscreenFix program that can fix the pixels of your screen. It is a good software. However, there is no guarantee that it will work for you.

Q3. How many dead pixels are acceptable?

Ans: This depends on who you ask. Some people say that 10 dead pixels are acceptable, while others say that 6 or 7 dead pixels are unacceptable. If you have a dead pixel, try to fix it as soon as possible.

Q4. Can dead pixels come back to life?

Ans: No, they can’t come back to life. Once a pixel is dead, it’s dead forever. However, stuck pixels can come back to life. Simply restart your device to restore a stuck pixel.

Q5. Is a dead pixel a defect?

Ans: Yes, the dead pixel is usually a manufacturing defect. It will always remain black and will not change color irrespective of what’s displayed on your screen.

The bottom line

So, if you’re experiencing any issues with your screen. Whether it is a dead pixel, a stuck pixel, or just a general feeling that something is not quite right, then our pixel test is definitely worth taking. It could very well save you from having to replace your entire monitor!
