Cause of White Spot on Laptop Screen
The cause of the white spot on your laptop screen might be because of something very easy to deal with, or you might have messed up the internal circuits of your display. But don’t worry, the latter’s chance is very low unless you dropped your screen, and it’s the worst-case scenario.
The most common cause of white spots on laptop screen is driver issues or a stuck pixel. Other reasons might include hardware failure, screen damage, loosely connected display cables, or loose LED reflectors.

Causes Behind White Spot on Laptop Screen
To identify the cause of the white spot on computer screen or laptop screen, you will have to inspect it case-by-case to understand your problem. There is no one reason for causing white spots on laptop screen. In the next section, we will go over each of the causes and give tips to troubleshoot them. Before troubleshooting, it is important to understand what is causing the problem.
1. Dead Pixels
On any screen, pixels are responsible for projecting the image and colours. There are millions of tiny pixels on a screen, and when a pixel stops working and can’t project any colour or image, it is called a dead pixel. Dead pixels are quite common, and when you notice multiple dead pixels in an area, you can see distortion in the image or a white spot. What may appear as dead pixels often might just be stuck pixels causing white spots. Dead pixels are difficult or impossible to fix, and stuck pixels are fixable.
2. LED Reflectors
There is something called LED reflectors in all the LCD displays. The LED reflectors are responsible for lighting the display evenly on your computer screen. When the LED reflector comes loose, the light may not be spread evenly. This may also happen when the LED reflectors have been forced out of the position. When this happens, you might notice white spots in the place where LED reflectors have come loose. This is repairable, although it might require replacing your display panel in some cases.
3. Hardware Failure
Any display is run by a graphics card or a graphical unit in cases of TVs and mobile phones. When these graphics units fail or do not function properly, you might see white spots on your display. Hardware failure is usually not easily fixable since the failure is on the graphics end and not the display. The display panel can also fail due to a manufacturing defect or any other reason. The hardware has to be replaced or repaired in both cases, which can be a costly affair.
4. Screen Damage
It is quite difficult to pinpoint this cause if you are unaware of any physical damage. If the white spots don’t have any distinct shape, it is most probably due to the physical damage to the screen. If you are unaware of any physical damage to your screen, inspect it for any visible signs of cracks, scratches, or dents. If there is physical damage, you most probably have to replace your display or get it repaired if possible. In any case, it will be a costly affair to fix this problem.
