All display devices constitute thousands or millions of pixels. These pixels are in charge of changing colors according to the projected image. However, a pixel can sometimes die or get stuck, leaving a dark or a permanent colored spot on your display. Let’s see how to fix them.

What are Dead or Stuck Pixels?

Dead and Stuck Pixels

Any fixed spot on display usually points to dead or stuck pixels. They are pretty harmless and are not always permanent. This hardware problem is caused by compatibility issues with some software applications, technical errors, or manufacturing defects. A stuck pixel is either green, red, or blue. A dead pixel, however, is always black. Let’s see how to check for dead pixels. 

How to locate dead pixels

Dead Pixel Test

Run a simple test online to locate dead or stuck pixels. There are many pixel checker apps available for Android and iOS as well. Other than that, you can even install any one of the tools mentioned below. They detect and repair stuck or dead pixels. 

How are dead/stuck pixels an issue for the users?

Even if the stuck or dead pixels are sitting somewhere in a corner, they still manage to grab all the user’s attention. They can be distracting and take away focus. However, they can also point to a more serious problem like monitor failure. 

How to manually fix stuck pixels

When no other tools can resolve dead or stuck pixels, then the user can try to fix this issue manually. Here’s a step-by-step process to make it happen.

Manually Fix Dead Pixels
  • Shut down the monitor
  • Take a damp cloth to avoid scratching the screen.
  • Now, put pressure on the area where the stuck pixel is located
  • Avoid putting pressure anywhere else as it may trigger the creation of more stuck pixels
  • Keep on maintaining the pressure and turn on the computer
  • Now, remove the pressure. The stuck pixel might be gone.

Why might this work? The liquid in sub-pixels of stuck pixels might not have spread evenly, and when you apply pressure, the liquid is forced out. When pressure is released, the liquid is pushed in. Hence, spreading it around as evenly as possible. This is how you can manually fix dead/stuck pixels.

Will dead pixels go away or spread?

No, dead pixels do not commonly spread. However, if they do spread, you need to either replace the screen or hire a specialist. There are high chances that those portions are permanently malfunctioned and do not go away with time. 

What causes dead pixels?

The most common cause is a manufacturing defect. But any physical damage to the display device can also cause damage to one or more pixels of your laptop or PC’s screen. 

Now, let us look through some useful tools to fix dead or stuck pixels on your Windows PC.
