Screen burn-in or ghosting is a discoloration of areas on an electronic display, such as a cathode ray tube display or an old computer monitor or television set, caused by the non-uniform cumulative use of pixels.

It occurs most often on AMOLED and OLED screens, but can also occur on IPS, TFT, or PLS screens and have similar effects.

The Burn-in Fix seeks to mitigate or eliminate the visual effects caused by ghosting and burn-in, forcing the entire screen to display primary and secondary RGB colors in a static and random way at a certain time interval.
