What is a dead pixel?
A dead pixel is a pixel on a display screen that doesn't work and remains either black or shows a single color all the time, regardless of what's being displayed on the screen. This is usually due to a failure in the individual sub-pixel components that make up a pixel, such as the red, green, or blue sub-pixel. A dead pixel can occur on any type of display screen, including LCD, OLED, and other types of displays, and can be a frustrating issue for users. It's important to understand the causes of dead pixels and how to diagnose them in order to determine the best course of action for fixing the problem. Check our article on what is a dead pixel for more extensive information.
How to test my screen for dead pixels?
A dead pixel test is a process used to check for dead pixels on a display screen. The basic principle of the test is to display a series of solid colors, such as black, white, and red, to cover the entire screen and make it easier to identify any dead pixels. Dead pixels are areas on the screen that are not displaying color or light, and they are easily noticeable when the screen is displaying a solid color. By playing the dead pixel test video full-screen, the user can see if there are any dead pixels on their display, which will appear as black spots on a solid-colored background. This process is simple, straightforward, and effective in identifying dead pixels on a display screen. Check out our article for more extensive information on how to run a dead pixel test.
How does a video dead pixel test work?
A video dead pixel test works by displaying a series of solid colors on the screen, allowing you to visually inspect the display for any dead or stuck pixels. The video cycles through different colors, including black, white, red, green, and blue, so you can check for any pixels that are not functioning properly. By running the video, you can identify any dead pixels, which will appear as black or white dots on the screen, or stuck pixels, which will be a single color that is different from its surrounding pixels. The video helps you to detect any issues with your screen, so you can take appropriate action, such as requesting a repair or replacement from the manufacturer if the screen is still under warranty.
To ensure accurate results when running a dead pixel test using a video, it is important to play the video in full screen mode and to adjust the video resolution to match your screen resolution. This will help to minimize any potential interference and ensure that the test covers all parts of the screen. Note that if you already have toggled the fullscreen mode on your phone and the video still does not cover all parts of your screen, you might try to zoom in with your thumb and your index finger. You may also consider playing the dead pixel test video directly from the YouTube app. It is also important to view the video in a well-lit environment to clearly see any potential dead pixels on the screen.

What to do if I have dead pixels on my screen?
If you have identified dead pixels on your screen after this test, there are several steps you can take to try to fix the issue. Here are some options to consider:
- Check your warranty: If your screen is still under warranty, you may be able to get it repaired or replaced without incurring any additional costs.
- Use a dead pixel fix video or software: There are several videos software programs available that claim to fix dead pixels. While these may not work for everyone, they can be worth a try. Our users have had good results with our dead pixel fix videos.
- Tap the screen: In some cases, tapping the screen near the dead pixel can help to jar it back into place.
- Physical repair: If all else fails, you may need to get the screen physically repaired or replaced. This can be done by a professional repair service or by replacing the screen yourself if you have the technical skills.
It's important to note that while some methods may work for some people, they may not work for others. If you're unsure about what to do, it's best to consult with a professional or check with the manufacturer of your screen.
