2. Pressure Method

  • Turn off your computer's monitor.
  • Get yourself a damp washcloth, so that you don't scratch your screen.
  • Take a household pen, pencil, screwdriver, or some other sort of instrument with a focused, but relatively dull, point. A very good tool would be a PDA stylus.
  • Fold the washcloth to make sure you don't accidentally puncture it and scratch the screen.
  • Apply pressure through the folded washcloth with the instrument to exactly where the stuck pixel is. Try not to put pressure anywhere else, as this may make more stuck pixels.
  • While applying pressure, turn on your computer and screen.
  • Remove pressure and the stuck pixel should be gone. This works as the liquid in the liquid crystal has not spread into each little pixel. This liquid is used with the backlight on your monitor, allowing different amounts of light through, which creates the different colors.
