What is the white spot on my laptop screen? It appears to be a dead pixel. Each LCD monitor consists of three small liquid crystal displays that produce red, green and blue pixels. When all three colors merge together through millions of these little dots, they create images on your Windows device. Unfortunately, only one of those red, green or blue subpixels is dead, which results in a white spot.

What does dead pixels look like?
There are physical defects of the monitor in which only one color (or even no color) is displayed. These anomalies are known as ‘dead pixels or stuck pixels’. when these kinds of failures appear, it’s generally just one pixel that continues to display the same image stimulus in spite of any changes made in terms of software.
For example, if a red pixel is dead, it will only display the color red even when you’re using your device to write a document in a different application. The main reason why these kinds of pixels are called ‘dead’ is that they do not respond to any stimulus and remain unchanged.

How to identify dead or stuck pixels?
In order to check if your device’s LCD monitor has any dead pixels, you’ll need to open up your device and look for them with the backlight of the screen off. In case you see a spot that does not change color when it should, it is probably a stuck pixel.
In order to check if your smartphone or tablet have any white stuck pixels, you’ll need to turn your backlight off. If the pixel does not respond, it is a dead pixel.
If you own any device and want to check if there are any dead pixels, we recommend downloading and using an app called Dead Pixel Test. It’s free and available for Google Android and Apple iOS devices.
When do dead pixels appear?
There are many factors that can lead to the appearance of dead pixels. The most common culprit is when your device is dropped and the LCD gets subjected to physical impact. Another reason why they appear is due to software failure, in which case you’ll need professional support so they can resolve it for you.
There is also a possibility that you might have a defective pixel, in which case it will always remain unchanged. In this situation, you’ll need to use a warranty or get it fixed by professional support staff.
How can you fix them?
There are many ways to solve this problem, most of which require professional support. If these kinds of pixels appear on your smartphone screen, there’s a chance that the touchscreen will stop working completely.
Options for fixing dead pixels depend on what kind of device you own (laptop or cellphone), as well as the brand and model of the screen. For LCD monitors, the most popular methods to get rid of dead pixels are:
● Using compressed air or a special tool known as a ‘dead pixel pen’ to gently rub your device’s screens surface and push stuck pixels towards their original positions.
● Using a can of pressurized air and spraying it directly at the dead pixel.
● Using a special software known as an ‘all-in-one fix tool’ to push pixels back to their original positions.
