Dead Pixels are a common problem that LCD screens face. When a pixel goes dead, the LCD monitor does not display the correct color output. In a dead pixel, all three sub-pixels are permanently off, producing a pixel that is permanently black. A stuck pixel is stuck on any particular color, it is always ‘on’. It can be repaired. They continue to receive power at all times. A dead pixel is simply dead and is mostly black in color. They do not receive power. It is difficult to fix dead pixels.
