How to use a dead pixel checker to test your dead pixels on your screen?

Are you sure if your screen is working fine? If not, then use a dead pixel checker to check if every color of every pixel is working perfectly well or if they have any problems. But before we proceed, let us have an idea of what a pixel and a dead pixel are.

Pixel: The tiniest component of your device’s screen is called a pixel. There are thousands of pixels in every image, video, and website. Since it is difficult to distinguish individual pixels up close, the image appears to have enough pixels to look natural.

Dead pixels are just "dots" or collections of dots that don't match the background color; for example, black dots on a blue background. One of the main reasons for the creation of dead pixels is the transistors that are stuck either switched “on” or switched “off”.

Dead pixels are actually quite prevalent, and occasionally manufacturers intentionally send defective monitors to the store and only replace them when the customer complains. Water damage and aging are the other common causes of dead pixels.
