Checking the monitor or screen
The computer’s screen or monitor has pixels. Pixels have three different colours: blue, green and red. These pixels can stop functioning properly when they get damaged. Any damaged pixels will appear black or display just one colour. The bad pixels are checked using an online tool known as “check pixels.” It works by displaying all the three main colours when the pixel is dead or damaged. A black spot can also appear to indicate if a pixel is malfunctioning.
