Superficial Debris
Sometimes, the spot on the surface of the screen is not internal at all. Instead, it will be dirt or debris stuck on the panel. And specks of dirt or debris might sound like something that you would not have to worry about, but over time, they can accumulate on the screen and form a more prominent spot.
Nevertheless, cleaning out the specks of dust from the surface is pretty easy. You will need to gather some basic materials.
First, get yourself a clean rag. A piece of microfiber would be the one we would recommend the most, but a clean cloth will also do the trick.
Next up, you just need to drag the cloth all over the upper surface of the display. That should work for most cases, but if the dust is engraved onto the screen, the specks might not fade away that easily. To get those stubborn dust and dirt out of the screen, you need to opt for isopropyl alcohol.
Drench the clean cloth with some 70 percent isopropyl alcohol and rub it on the screen. Ensure you are not putting too much pressure because the panel underneath can get damaged if you put too much pressure on the surface.
Once the cleaning process is done, dry up the upper surface using a clean and dry cloth. Again, microfiber cloth would be our pick in this case. When the screen is dry, you can start using the laptop normally.

How to Observe the Spot on the Screen?
It will not always be the case that superficial debris will be on the top of the screen. There can be a stuck pixel present as well. As the name suggests, a stuck pixel means that the pixel can not change color. And when the pixels can not change colors, they will stick with a single color, making a dark spot on the screen.
Now, you might wonder how to be sure that there is a stuck pixel on display? Follow these steps:
Step 1: Switch the Screen off
First, you need to turn the screen off. You would need to check whether there is any superficial dust or dirt on display at this moment. If there is any, follow the process we have mentioned above and get it off the surface.
Step 2: Turn It Back on and Get into the LCD Test
Now, press the power button and button D at the same time. These buttons will initiate the self-test designed for the LCD. Once it starts, there will be several blinking lights on the screen.
Step 3: Observe the Display
The blinking colors will give away whether there are any distortion, lines, or spot problems on display. So, you would need to look into the screen during this test closely. Once the test is complete, the laptop will restart automatically. If you fail to properly notice the defects, consider rerunning the test.

What Is a Dead Pixel?
Like the stuck pixel, the dead pixel is another internal defect of LCDs. On the stuck pixel, the pixel would light up, but it will have a single color. The colors will not change, nor will you be capable of viewing pictures on the screen properly.
However, for the dead pixel, the pixel will not light up at all. In other words, there will be no output from that pixel at all.
Why Do Dead Pixels Occur?
Dead pixels are something that will occur on the panel automatically. It is basically a manufacturing defect. However, physical damages can even initiate dead pixels. Bumping or knocking the display over can cause it. It will make the pixel lose power to the panel, which will kill it.
How to Avoid Dead Pixels?
The best way to avoid getting a panel that has a dead pixel on the top would be to select a high-quality display. Avoid getting laptops that utilize screens from no-name brands or off-brands. Instead, opt for the models that rely on the panels that are from reputed manufacturers.
Secondly, avoid bumping into the display. As we mentioned, bumping or rocking the display over can cause dead pixels to occur. Be a little careful while opening the lid of the laptop because too much pressure on the top of the display can also kill the pixels.

How to Fix Dead Pixels?
Even though it might sound impossible, dead pixels can be fixed. Follow these steps:
Step 1: Turn the Screen off
Before anything else, you would need to turn the display off. And run the LCD screen test. For that, you would need to press the power button and the button D at the same time. As we have mentioned before, it will initiate the self-LCD check mode.
While the test is in progress, keep in mind which pixels are dead. If possible, click a picture of the screen. That will come in handy in the next steps.
Step 2: Get Yourself a Damp Cloth and Work on the Pixel
Find a clean, non-abrasive cloth. Use a little bit of water and dampen it. Ensure that it is not soaking wet, or else the water droplets can end on the keyboard, which can cause other issues. While the screen is off, you need to gently apply pressure on the spots that have dead pixels.
However, you should keep one thing in mind that if you apply pressure on the other spots, you might initiate dead pixel creation on the other locations. Keep on applying pressure on the actual spots and turn the laptop on. When the screen lights up, wait for a couple of seconds and remove the pressure.
Step 3: Clean the Surface
After removing the pressure from the spot, you will notice that the dead pixel is no longer there. The gentle pressure will make the pixel connect back to the panel and get power again. And once you are done with the process, get yourself a clean rag and clean any of the water on the surface.

How to Fix Stuck Pixels?
The manual process of fixing stuck pixels is the same as dead pixels. Stuck pixels also lose the connection and hold the last pixel that was on the screen. To fix it manually, you can follow the steps that we have mentioned for dead pixels. However, if that does not work out, you can try out web-based services.
There is plenty of stuck pixel fixes on the internet. They will mostly be HTML-based and will fix the stuck pixel by forcing it to act normally again. And the best part is, you do not have to download anything, nor will you have to install any software on your laptop.
Among all of the available options, we would recommend checking out JScreenFix. It is a simple web-based fixing tool that will utilize the pixel-fixing method. Get into the website and scroll down. You will find a button that states, “Launch JScreenFix.” Press it, and everything should turn black apart from a small window.
You would need to drag that small window into the locations where the stuck pixels are. Keep that small window on those specific places for about 10 minutes. In other words, each of the stuck pixels will require about 10 minutes of that fixing. After that, check whether the stuck pixel is still present on those spots.
Conclusion on How to Fix Black Spot on Laptop Screen?
It is pretty natural to panic when you see a black spot, dead pixel, or stuck pixel on the screen. However, you can get rid of them in just ten minutes now that you know how to fix black spot on laptop screen.
But the fixes might not really work for all of the cases. For example, the fixes will not work if a manufacturing defect or physical damage is present on the screen. In those cases, you would need to get a replacement or claim the warranty if it is still available.
