How to fix Black Spots on my Laptop Screen?

Dead pixel on laptop screens remains black as the light does not reach these spots. To make sure you are fixing the computer screen, identify whether the screen has dead pixels or just accumulated debris for several hours or even weeks.

Computer screens are usually just like the LCDs that we use in our other everyday use devices. However, many times people observe a black patch on their computer screen.

If you are facing a black spot on your computer or laptop screen then there may be a problem with the LCD or this might just be an issue of debris black spots or dirt left unchecked and accumulated over a long period.

When it is left uncleaned it leads to the formation of a huge black spot on the computer screen.

In any case, this problem can be solved easily. You can apply simple hacks or use software tools to remove the black patches from your computer screens. I have fixed my black patch issue with just a cotton bud.

You can use any fix that suits your issue. I have listed below a number of solutions that you can apply to this issue.

What causes black spots on LCD?

Black spots will always be visible on liquid crystal displays in a plasma screen once the power goes off. The reason for the occurrence of dead pixels is usually a defective transistor. This transistor makes the pixels get stuck in an “off” state permanently. Hence, they are completely black.

Although this is a serious issue at times it is usually because of a problem with fluid distribution. You can get the computer monitor replaced by the manufacturer once it exceeds a certain percentage of acceptable dead pixels.

Whereas, the stuck ones can get stuck because of poor insulation in the liquid distribution or the transistors getting stuck on a permanently “on” state in a specific color.

These distribution issues can be fixed. This article will discuss the ways to fix these issues.

The problem of black spots can be prevented through the use of good research methods and prevent costly mistakes. This may mean you can do nothing at all when your screen is not aligned with the screen.

The international media group has discussed this issue a few times as well in the leading digital publisher. The current user bookmark for this issue is also very high.

Black Spot on a screen

How to Fix Black Spot on Laptop Screen?

1. Superficial dirt or debris

It’s mainly possible that Black spots have been brought on only after soaking up some of the soil in an area with surface dust. Debris and dirt settle onto LCD’s surfaces over time. The black spots do not affect the input of an LCD or damage the inner circuit of the laptop LCD.

To clean the debris or dirt, do the following steps,

  1. You can wash the screen using a soft non-saturated micro-cleaning towel.
  2. Gently rub the small cloth lightly under the LCD panel when it is shut off until the black surface is no longer visible.
  3. Cleanup of a black surface is a good idea.
  4. Clean the computer screen if superficial dirt has created dark patches.

2. Dead Pixel

It is known that a stuck pixel could cause black spots or even a flicker. If the display is switched off, the tripped pixels are lit and not changed to white. On the other hand, dead ones would not be discarded. This means all three dead pixels – red green and blue – will always be turned off permanently.

And due to the lack of illumination, the dead ones will be like black points on the projector like those of dark spots on the projector.

3. Stuck Pixel

A stuck pixel is anything in an LCD that can’t change its color. Line sizes vary in color from one photo to the next. A photo is an image displayed on a television. If no color changes to a pixel the color has been stuck.

Black spots can often be found on LCDs or HP laptop screen because there is a visible black area on the LCD. To solve the dead or stuck pixel refer to the next fixes and try them according to your preference.

4. Tap the Spot on the Computer Screen

This may sound odd but it is a tested and working solution of the black patch on the monitor. All you have to do for this is to tap.

To apply this method, you will have to make sure that your monitor is on. You can display a darker window through a screensaver for help.

Use a round-ended and dull item like the end of a pen, a stylus pen, a sharpie, or a pencil eraser to get rid of black patches. Use pressure to tap the spot on the display. The pressure should be enough for you to see a white spot on the area of pressure.

To summarize the solution into steps,

  1. Take a dull and round-ended object like a sharpie, a pencil’s eraser, or the end of a pen.
  2. Turn the monitor on and change the screen saver to a dark or black screen.
  3. Apply pressure on the black spots using the object in step 1. Apply enough pressure that you can see a white spot every time you press.
  4. Repeat until the display area change color.
  5. Change the screensaver to white to check.

If this solution does not work for you, try the next ones.

5. Apply Pressure on the Area

Another simple yet efficient method is that you apply enough pressure to the area using a simple microfiber cloth, lint-free cloth, or even a pencil-like in the previous solution. Turn off the monitor for this one as you need a dark window.

You can simply fold the cloth twofold and apply pressure using the cloth on the dead pixel area. Continue the process until you can see that the color has been restored. Do not apply too much pressure.

To summarize the steps, do the following diagnostic test,

  1. Turn off the monitor.
  2. Take a simple and soft cloth and fold it twice. You can take any object from the first solution as well.
  3. Apply pressure on the black path on the LCD to fix it.
  4. Repeat the process until the LCD’s color is restored.
  5. Turn the monitor on to check if the solution has worked.

The next method is also very simple and easy.

6. Use a Damp Cotton Bud on the Area

This method has been used the most recently as it has proven visibly effective and generates instant results.

To solve the black patch on-screen use a damp cotton bud on the target area. Keep the monitor screen on and make sure you can see it.

Apply sliding pressure on the spot using the cotton bud in a way that you are pushing the dead patch outside the screen.

You should be able to observe the black patch sliding towards the direction of the pressure.

To summarize this method, do the following,

  1. Turn the power button on.
  2. Display a white screen to view the black patch.
  3. Take a cotton bud and spray it with water to make it damp.
  4. Apply pressure on the black patch using the cotton bud in a sliding direction.
  5. Observe the black patch moving. Repeat the process until the patch disappears.

This is a simple and easy method for the broken pixel in the LCDs of laptops. If you wish to use a software fix instead, check the next fixes.

7. Use a pixel fixer software to fix the black patches

If you do not want to apply any kind of pressure on the monitor or you fear you might puncture it, you can always use software or web-based service.

There is much free software that allows the users to remove the black patches or in other words, dead pixels from their system screens. I will list some of these software pieces for you to try.

1. UnDead Pixel for Screen Repair

You can use this software even if there are no visible black patches on your screen. As there is always a possibility of some damaged pixels existing on the screen.

The software UnDead Pixel will change the color of the LCD after fixed time intervals. This will help in the removal of any unresponsive pixels and hopefully revive the screen back to life.

2. JScreen Fix

The other software available are Rizonesoft Pixel Repair, Aurelitech’s PixelHealer, dead pixel buddy, and Pixel Doctor. 

You can use any software and hopefully solve your issue.

Tips for dealing with Unexpected Pixels on Display Screen

If defective or broken pixel cannot be removed from your display screens it might be defective or died. Rerun the Pixel Solution app to see if this fixes the damaged pixels for a few hours of time. To recover missing pixels from the display, make it clear to the LCD manufacturer.

In certain cases, if you already have a warranty and meets the repair criteria the LCD supplier will replace the screen. LCD producers are planning to sell some monitors with defective pixels. Choosing to choose an HD LCD panel with real user input is an important choice.

Dead pixels are the toughest fixes while stuck pixels are more difficult to patch. The problem is superficial Dirt and debris are the easiest to repair problems but dead pixels are hard to fix than stuck ones or broken pixels. The article discusses the fixes for all of these problems.
