How to check the monitor for dead pixels and get rid of the problem
In all LCD monitors, images are created from a grid of pixels. The size of a monitor, like 15 inches or more, does not matter. Pixels contain three separate sub-pixels of red, green, and blue.They are in charge of the multi-color structure of the picture.
To avoid dead pixels, you should check the screen before you buy. You can do it yourself or pay for the corresponding service in the store.
Questions and disputes often arise regarding dead pixels due to the subtleties in the manufacturer’s warranty conditions. Visually, the absence of defective pixels can be determined by careful examination on a solid white, black, red, green, and blue background. To do this, you need to upload such pictures to a flash drive and play them on your favorite device. If none of the dots are out of color, then the screen is fine.
How to remove dead pixels?
Since black pixels are the result of transistor damage, they cannot be fixed without replacing these components. And it’s almost unrealistic. The situation is different with colored dots, which arise due to the freezing of subpixels. You can try to remove them.
The method consists in cyclically displaying rapidly changing images. This may increase the chance of returning the ability to switch again to the stuck pixels by changing colors.
There are many ways to implement this method through special apps and of course YouTube videos:
- Bad Pixel is a professional paid app for Windows that can help you remove dead pixels in several minutes.
- DeadPix is a cool program for Windows and Android. It is useful when you need to find and then fix dead pixels by cycling colors.
- PixelHealer is another utility for Windows. It eliminates stuck pixels with quick RGB coloring.
- JScreenFix is an online service to run on your PC, TV, and mobile devices. Displays a digital noise area that you can move to the right area of the screen.
- PixelFixel is a 12-hour YouTube video. The colors in the video change at a very high speed and can cause epilepsy. Do not look at the screen, but rather turn it aside.
About annoying monitor problems
A display may not turn on because it may have come into a faulty state. In other words, it is broken.

The exact problem can be determined by a specialist whose task is to diagnose. Complicated laptop or computer repairs should be trusted only by specialists.
As well, a 100% lack of inclusion can only be fully diagnosed by a specialist. Various problems can be responsible for the black screen. Some are responsible for quick and simple problems, others for serious ones, the elimination of which is recommended exclusively by the master.

When considering issues that might arise when turning on a computer, it is not recommended to rely solely on your knowledge. You should at least consult a professional. Perhaps behind the black screen hides a more serious problem than the wrong settings.
