Usually, the liquid in one or more of its sub-pixels will pass through to create different colors and spread equally. These are manual methods of resolving stuck pixels by combining pressure and heat.īefore you start, turn off your monitor, and using a damp cloth, apply pressure to the spot where the stuck pixel is, without affecting other areas as this may create more stuck pixels.Īs you apply the pressure, power on the computer and your screen, remove the pressure and then check if the stuck pixel disappears.

Stuck pixels are stubborn little squares that maintain a single color all the time, but they’re not always permanent. Malfunctioning or stuck pixels have plagued monitors since LCD (liquid crystal displays) screens came on the scene.
