Dead pixels on the display — how to find and fix the defect.

Small black dots on the screen can spoil the pleasure of watching your favorite series as they distract attention. Most often, these dots are 'dead' pixels that remain dark when other parts of the screen change color. This is reported by SlashGear.

Why 'dead' pixels occur and how to fix them

A 'dead' pixel is a small square that does not light up at all, while a 'stuck' pixel continuously lights up in one color (red, green, blue, or white). Usually, the reason for a 'stuck' pixel is a transistor failure, which can be fixed, while 'dead' pixels often arise due to a manufacturing defect or physical damage to the matrix.

To determine how serious the screen issue is, you need to identify the type of defect. A few isolated 'dead' pixels do not affect performance, but their spread can reduce the usable screen area and complicate the use of the touchscreen. To check the screen, you can use special tools.

• Open the site testmyscreen.com;
• In the hamburger menu, select Solid Colors — the screen will turn white;
• Look for black spots, check the screen on a black background for bright dots;
• Look at multicolored screens to spot the problematic pixel.

If none of the methods help to identify the problem, you may need to contact a service center for a matrix replacement. Interfering with the screen using improper means can damage the coating, so it is advisable to use only safe methods.

Also, keep in mind that in the near future, plasma television technology will become a legend as it is being replaced by newer screen technologies.

Non-functional pixels on a television or monitor screen can arise due to various reasons, including physical damage or manufacturing defects. It is important to be able to distinguish between 'dead' pixels and 'stuck' ones and to know how to properly check the screen and solve the problem for maximum comfort in using the equipment.
