So whether you’re an experienced technician or a complete beginner, you’ll find all the information you need to get your laptop back to its best in no time.
What Causes Black Spots on a Laptop Screen?
Black spots appearing on your laptop screen can be a frustrating and concerning issue. It is important to understand the potential causes of this problem in order to prevent further damage.
There are several factors that could lead to the appearance of black spots, and it is crucial to consider each one in order to determine the root cause and take appropriate action. Let’s explore the most common causes:
One of the main causes of black spot on a laptop screen is dead pixels. A dead pixel is a small, non-functioning area on your laptop screen where the light-emitting diodes (LEDs) or liquid crystal display (LCD) do not produce the correct color output.
This often results in a tiny white or black dot/spot on the screen or you can say noticeable dark area on the screen that does not disappear even when the rest of the display is functioning normally.
Black dots can be appeared on any type of display, including laptops, monitors, televisions, and mobile devices. Dead pixels can occur due to manufacturing defects, physical damage to the screen, or simply as a result of normal wear and tear over time.
It is also important to remember that a black spot on your laptop screen may also be caused due to stuck pixels
In addition to dead pixels, another common issue with displays is stuck pixels. Stuck pixels are pixels that get “stuck” on a certain color and fail to display the correct color output. This can result in a Black, white or colored spot on the screen, which can be distracting or annoying.
Dirt or Debris:
One potential cause that creates black spot on a laptop screen is the buildup of dirt and debris. When tiny particles such as dust, dirt, or other debris settle on the screen’s surface of your laptop’s screen, they can create a dark spot that looks black.
This happens because these particles block the light that passes through the screen, resulting in a shadow/dark area or you can say black spot. Over time, the accumulation of dirt and debris can make the spot more visible and even affect the overall display quality of the screen.
LCD burn-in, also known as image retention, can cause black spots on a laptop screen if a particular image is displayed on the screen for an extended period of time. This can happen because the pixels that make up the display can become “stuck” in their on or off state, causing a permanent dark spot on the screen.
If the black spot is caused by LCD burn-in, it is usually visible even when the laptop is turned off, and it may be more noticeable when the screen is displaying a light or white background.
Physical Screen Damage:
Physical screen damage is a very common issue that can cause black spots/dots on your laptop screen. Laptops screens consist of multiple layers, including a backlight, liquid crystals, electrodes, and filters. When the screen is physically damaged, it can interrupt the flow of electricity to the liquid crystals, resulting in the affected pixels failing to display color correctly.
This can cause the area to appear black, white or any other color depending on the severity of the damage. The size and shape of the black spots depend on the extent and location of the physical damage.
Accidental damage, such as dropping your laptop or applying excessive pressure to it, is the most common cause of physical screen damage. However, manufacturing defects or faulty components can also contribute to the problem.
Graphics card failure:
A graphics card is an important component of a laptop that helps to display images and graphics on your laptop screen. When there is an issue with your graphic card and it is not working properly, it can cause black spots or missing pixels to appear on you laptop screen.
Actually, this happens because the graphics card sends signals to the screen, and if it’s not functioning properly, it may send incorrect signals that result in distorted or missing pixels. These pixels may appear as black spots on the screen.
Moreover, a faulty graphics card can also cause the laptop to overheat, which can damage the screen components and lead to black spots on the screen.
Black spots on your computer screen can also be caused by various software-related issues, such as outdated or corrupted graphics drivers, software bugs, conflicts between applications, malware or viruses, and outdated operating systems.
Graphics drivers are essential software programs that communicate with your graphics card to display graphics on your computer screen. Outdated or corrupted graphics drivers can cause issues with the display, including black spots.
Similarly, software bugs or conflicts between different software components can also cause black spots on your screen or other visual anomalies. Conflicts between applications running on your laptop are another potential cause of black spots. This can happen when two applications are competing for the same system resources, such as RAM or CPU usage.
In some cases, malware and viruses can also cause black spots or other visual anomalies on the screen. Certain types of malware are designed to manipulate your computer’s display settings or interfere with the functioning of your graphics card, resulting in black spots or other display issues.
Laptop Hardware Issues:
If you’re seeing black spots on your laptop screen, it’s usually an indication that something is wrong with the hardware that controls your display. Even though modern laptops have high-resolution screens that display sharp images and visuals, but still hardware issues can cause black spots to appear.
One common cause for black spots is screen bleeding. This occurs when light from your laptop’s backlight “bleeds” through to other parts of the screen, causing dark spots to appear. So if you’re experiencing screen bleeding, you might see dark black spots showing up on your display.
Now that you’re familiar with the most common causes of black spots on your laptop screen, it’s time to take action and get rid of them. We’ll show you four effective ways to fix these black spots.

2) Removing Dirt or Debris on Screen to Fix Black Spots
As you know black spots can also be caused by dirt or debris buildup, so cleaning the screen is often an effective way to remove these spots. If you have black spots on your laptop screen due to dirt and debris, here are three steps you can follow to remove them.

Whenever you are in the market for a new laptop purchase, it’s important to check for any black spots on the screen. Here are some tips for testing the screen before you buy:
- Inspect the screen closely: First, inspect the screen carefully before turning on the laptop. Look for any physical damage like cracks, scratches, or discoloration. If you see any of these, it’s likely that the screen will have black spots or dead pixels.
- Display a solid color image: Next, display a solid color image like black or white and examine the screen for any black spots or dead pixels. Pay special attention to the corners and edges of the screen.
- Check the screen from different angles: Make sure to check the screen from different angles, as some spots/dots may only be visible from certain perspectives. Sometimes, a screen may appear fine from straight angle but have issues when viewed from a different angle.
- Test the screen with different backgrounds: Another thing you can do is display different backgrounds or wallpapers to see if any black spots or dead pixels are more noticeable with certain colors. By doing these tests, you can reduce the likelihood of purchasing a laptop with screen issues.
- Inspect with Software Tool: While inspecting the screen for physical damage and displaying solid color images are good first steps, they are not always conclusive. To test in more detail, you can use a screen testing tool like Eizo Monitor Test. This will help you easily identify any faulty pixels on your laptop screen.
By performing these tests before purchasing a laptop, you can minimize the chances of ending up with a laptop that has black spots or dead pixels on the screen.
