Monitors use pixels to display images that make it possible for you to interact with the computer. These are tiny transistors made out of three colored parts and can become defective over time or not function from the start. Even if considerably small on a screen, a dead pixel can be a pain. Luckily, with applications such as Dead Pixel Locator you can find out whether or not it's time to take your monitor to maintenance.

There are several reasons you might encounter defective pixels, be it because of its age, or brand manufacturer policies in this regard. Monitors are categorized in classes, with the top ones not passing validation even if one pixel is defective. Lower ones however, might be sold faulty and have the screen changed if the customer notices the defect.
