A dead pixel appears as a small dot on your screen that does not change color no matter what is displayed. It can be black, white, or even stuck on a certain color, distinguishing it from surrounding pixels. Such pixels are typically a hardware issue, meaning the tiny transistors within the screen fail to activate or deactivate properly. Spotting dead pixels early on is crucial for potential repair or replacement decisions, as they can be bothersome during daily use.
