Dealing with Dead Pixels: A Guide to Fixing and Preventing Black Dots on Laptop Screens

Black dots on laptop screens are a common issue that many laptop users face. These dots are also known as dead pixels, and they can be quite frustrating for users, especially if they are in prominent areas of the screen. In this article, we will explore what causes black dots on laptop screens and what you can do to fix them.

What are Dead Pixels?

Dead pixels are tiny black or colored dots that appear on laptop screens, LCD monitors, or televisions. These dots appear when the pixels on the screen stop functioning properly. Each pixel on a screen is made up of three sub-pixels: red, green, and blue. When these sub-pixels stop working, the pixel will not display the correct color or may appear black.

Causes of Dead Pixels

There are several causes of dead pixels on laptop screens. The most common cause is physical damage to the screen. This damage can occur when the laptop is dropped or bumped, causing the screen to crack or become damaged. Dead pixels can also occur due to manufacturing defects in the screen.

Another cause of dead pixels is age. Over time, the screen may begin to degrade, and dead pixels can appear. This is more common in older laptops and monitors that have been in use for many years.

Fixing Dead Pixels

If you have dead pixels on your laptop screen, there are a few things you can do to fix them. The first thing you should try is to run a pixel fixer program. These programs work by flashing different colors on the screen to try and unstick the dead pixel. There are many free pixel fixer programs available online, and they are easy to use. Simply download the program and follow the instructions to run it.

Another method to fix dead pixels is to apply pressure to the affected area of the screen. This can help to unstick the pixel and get it working again. To do this, turn off your laptop and place a soft cloth over the screen. Gently apply pressure to the area with the dead pixel using a finger or the eraser end of a pencil. Be careful not to apply too much pressure, as this can cause further damage to the screen.

If the above methods do not work, you may need to replace the screen. This can be a costly and time-consuming process, so it is best to exhaust all other options before going this route.

Preventing Dead Pixels

Preventing dead pixels on your laptop screen is not always possible, but there are some things you can do to reduce the risk. The first thing is to be careful when handling your laptop. Avoid dropping or bumping it, and always store it in a protective case when not in use.

Another way to prevent dead pixels is to avoid leaving static images on the screen for long periods of time. This can cause burn-in, which can lead to dead pixels. If you need to leave an image on the screen for an extended period, be sure to use a screensaver or turn off the screen when not in use.

Finally, you can also reduce the risk of dead pixels by purchasing a laptop with a high-quality screen. Look for a laptop with an IPS or OLED screen, as these screens are less likely to have dead pixels.


Dead pixels on laptop screens can be a frustrating issue for users. They can be caused by physical damage, manufacturing defects, or age. Fortunately, there are a few things you can do to fix dead pixels, including running a pixel fixer program, applying pressure to the affected area, or replacing the screen. To prevent dead pixels, be careful when handling your laptop, avoid leaving static images on the screen, and purchase a laptop with a high-quality screen. With these tips, you can reduce the risk of dead pixels and ensure that your laptop screen stays in top condition.
