You have found a black patch on your laptop screen; you are not alone! Discovering a black mark on your LCD can be disheartening, but you can take a few steps to get rid of it. So, if you are here to learn how to fix a black patch on a laptop, read this blog till the end without skipping any parts.


The black spots are just surface blemishes that occur when dirt or other particles lie on your screen or due to some defects with the LCD pixels. No cracks or tears may cause the display to fail shortly, and it's certainly not an indication of broken glass. Even so, these can easily be fixed; it is crucial to have an accurate understanding of what causes the patches so you can take measures to prevent them from appearing again.

Dirt or Debris


A laptop or LCD monitor's screen is like a mirror, reflecting the light from your laptop's display back at you. Black spots on display appear when small amounts of dirt, dust, or smudges gather and are stuck to the surface. 


Sometimes, dirt on your laptop screen may pile up, making black spots visible to the naked eye and growing more significant over time. It can cause problems with screen resolution if left untreated. 


These dirt patches are easily removable without causing any damage to the monitor. However, failing to clean the dirt regularly will cause more of it to occur and rapidly obscure more of your laptop's screen, making the rest appear duller by comparison.


Though such black marks will not reduce the quality of the display of your LCD screen and cause any damage to the internal circuit of the monitor, they are very annoying. But these dirt patches still affect your laptop's screen resolution.


The quick method to get rid of these spots is to clean your screen with a moderately dampened microfiber cloth or soft eraser. Do not apply pressure while rubbing the display; wipe it with gentle, circular strokes to avoid scratches and leftover marks.


Pixel Defects on a Laptop Screen: Dead Pixel vs. Stuck Pixel

Different pixel defects happen on LCD screens, including dead and stuck pixels. Figuring out the problem will help you choose the correct resolution methods that will not further damage the screen. When you understand which defects it is, it becomes easy to find a solution on how to fix these black spots.


Most laptops have some pixel issues in them. The number of defective pixels you see depends on the screen resolution – the smaller the resolution, the larger they seem. In most cases, they are not noticeable because of regular use; you can't see them with your naked eyes as they are not bright spots, and if your laptop is free from pixel issues when you purchased it, consider yourself lucky.


Laptop screen manufacturing technology has improved dramatically over the years, and today's panels almost don't come with any such problem.

Dead Pixel 

When a pixel gets permanently damaged, it fails to receive power, resulting in a dark or black patch on your laptop screen. This specific flaw can appear during the manufacturing process of a laptop screen, and it is permanent and does not recover over time. 


Nonetheless, one can rarely experience such defects on laptop screens out of the box since manufacturers attempt to follow stringent quality control processes to ensure they deliver a non-defective product. On the other hand, it's pretty standard to notice dead pixels appearing on the screen over time, depending on multiple usage factors.

Stuck Pixel

Stuck pixels can be powered on, which leads to a permanently colored pixel. They can be any of these three colors – red, blue, or green. While dead pixels are permanent, a stuck pixel might disappear. You can remove this defective pixel just by doing some simple steps.

Dead pixels are permanent pixels that remain powered off, meaning they will appear as black patches on the screen whenever you turn your laptop on. 

On the other hand, stuck pixels are not dead and can receive power like normal pixels, although they always get stuck on a single color: red, blue, or green.


In a dead pixel, all three colored sub-pixels – red, blue, and green, are forever "dead" or turned off and can't be illuminated, so it looks like a black spot to our eyes.


Use pixel-checking software

However, those who face such problems know that it's pretty tricky to differentiate between dead and stuck pixels with the naked eye; therefore, you may need to look for other ways. If you are using a Windows laptop, install a free software named "InjuredPixels" – you can Google its official website and download it from there. Or if it's a Mac, "LCD DeadPixel Test" is a browser-based tool (so nothing to download or install) that can help.


Spotting defective pixels is relatively easy using these third-party apps. They run single solid colors on your display so that you can quickly find the glitch pixel by matching the color of the rest of the screen real estate. You can further ensure whether it is a dead or stuck pixel (by considering the colors) before you attempt to fix it.

How to Fix Black Patch on a Laptop?

Stuck pixels are often temporary and usually go away after some time without requiring you to do anything.

Alternatively, you can turn the laptop off for about an hour and then turn it on. Repeat the process a few times and check for changes in the pixels. This simple method is especially beneficial if the stuck pixel shows when running a specific program and not at other times.


In disparity, a black spot due to dead pixels is a more complex problem and hard to fix. You can find the few expert-recommended methods with comparatively higher success rates below.


1. Gently Rub the dead pixel area with mild pressure: 

If you find that your LCD monitor display has dead pixels, there are a few things you can try. One of the simplest things to try is rubbing it gently, mainly if the dead pixel is on the edge of your screen where it is barely noticeable. 


Before you try this technique, your panel must be clean and free of dust and debris. Simply wiping with a soft cloth should remove most dirt and smudges. Also, using an object with a circular end, such as a smartphone stylus, and placing a soft microfiber cloth over the problem spot during the process will significantly reduce the risk of causing more harm to the screen. 


2. JScreenFix (third-party tool):

JScreenFix is a website that can help you with dead or stuck pixel issues. No expensive equipment or software is required, as using the site is 100% free. All you need is your laptop and an active internet connection, and you are ready. Below are step-by-step instructions to walk you through the steps to resolve the problem!

  1. Before attempting this fix, leave your laptop powered off for at least two hours to ensure its internal components are completely relaxed.

  2. Now, start your laptop again and open on an updated browser. 

  3. Click on the Launch JScreenFix box.

  4. Your screen will go dark, and a colored pixelated box will appear, which you can move around your screen easily using the mouse.

  5. Place the box in the problem area and let it do its job for around 10 minutes. You can let the program run for up to 1 hour if needed.


The box makes all the pixels within the region shift between multiple colors rapidly, forcing the dead or stuck pixels to be restored effectively.


I hope you understand your issue with the laptop screen and know the methods for fixing such spots. Before looking for how to cure black dots on a laptop, it's crucial to figure out precisely what caused them. Usually, the issues people face are minor, and the black areas on their screens result from dust and dirt accumulation, which can be fixed with a simple cleaning.


However, sometimes, it might be a symptom of a more significant problem, including dead and stuck pixels that may require professional help. Unless you know what you are doing, we recommend you take your laptop to an authorized repair service center or laptop-exclusive store near your place to claim a replacement from the brand if it's still under the warranty period.
