Choose from different colors to identify dead pixels. By default, you can turn the screen black, white, red, blue or green. Or, pick a different customized color if you wish. Whichever hue you choose, the whole screen turns this color so that you can tell if one of the pixels on your monitor isn’t responding properly.
Dead Pixel Buddy is a user-friendly platform that’s lightweight and doesn’t require any installation. This app helps you to tell whether your monitor has a dead pixel in a matter of seconds. Also, this test is particularly useful when you buy a new screen since they sometimes come with pixels that don’t respond to certain colors.
