Dead screen is a concept that technology users always avoid. So what is it that makes many laptop users so afraid? Let’s find out with Tnhelearning.edu.vn through the following article!

What is screen dead point?

Dead Pixel refers to one or more points on devices such as desktop computers, tablets, etc. when active but does not display the correct colors like other points on the screen.

One point that identifies the screen dead point is that this point displays white, black or dull colors compared to other color points on the screen.

What causes screen dead spots?

Computers are made up of millions of pixels (pixels) to display colors and images. So the screen dead point is the faulty pixel and this error usually appears when the screen is degraded due to too long use .

Types of screen dead spots

In addition to the concept mentioned above, there are cases that are almost like:

• Dead Pixel is the position where that pixel cannot display colors on the screen.
• Stuck Pixel is the position where that pixel can only display a single color . You must choose a wallpaper with an appropriate color for that pixel to display the color in full screen sync.
• Hot Pixel is the position where that pixel is clearly visible on a black background .

How to detect dead spots on the computer screen

Step 1: Arrange the computer screen systematically to easily detect screen dead spots.

Step 2: Right-click on an empty space on the screen -> Select Personalize .

Step 3: Click Background on the left side of the dialog box -> In the Background section on the right, click the down arrow -> Select Solid Color -> Choose a color to display on the desktop.

The desktop screen will now only display one color, look closely on the screen to see if there are any dead spots or change the background to another color to be sure.

Does the screen dead point spread out?

Although the dead spot is a situation that people always avoid, the good news is that the dead spot on the laptop screen will not be spread . If your laptop screen only appears 1-2 very small dead spots, you can safely use it.

However, if your laptop has been used for a long time, the screen has been degraded, now the number of dead spots will appear more. In other words, screen dead spots do not spread, but the number of dead spots can increase.

How to fix screen dead spots?

Some ways to fix dead screen:

• Use your finger to gently press on the screen, the area around the dead spot.
• Use UDPixel software or JScreenFix.com website to fix dead spots on the computer screen.
• If your screen has appeared many dead spots, it is recommended to replace the module with a new one . You should pay attention to replace it at reputable stores with warranty instead of replacing it yourself at home.
• If it is an LED screen , it can be fixed by going to a reputable shop to re-solder the compatible LED chip to the module plate with lost pixels .

Warranty from the manufacturer

The screen dead point appears mainly from the manufacturer, so all laptop manufacturers have regulations on the screen dead point warranty.

For example, Dell laptops specify the number of allowed dead points from 5 to 6 points . This means that, if there are more dead spots on the Dell laptop screen than this allowable number, then you will be required to have the screen under warranty.
