Stuck PixelĪnother common cause of black spots on LCDs is a stuck pixel. With the LCD turned off, gently rub the microfiber cloth across the screen until the black spot is no longer visible. You can clean your LCD’s screen using a damp - not soaked - lint-free microfiber cloth. Nonetheless, it’s a good idea to clean your LCD’s screen if superficial dirt or debris is creating a black spot. The black spots won’t affect the performance of an LCD, nor will they damage the LCD’s internal circuitry. If left unchecked, this dirt or debris may manifest as one or more black spots. Over time, dirt and debris will accumulate on the surface of LCDs. Superficial Dirt or Debrisīlack spots are often caused by nothing more than superficial dirt or debris. By understanding what causes black spots on LCDs, however, you can take the necessary precautions to prevent them from occurring. When you fire up the LCD, the black spot will probably be the first thing you see.
