Hot Pixel

A hot pixel is a pixel that, unlike a dead pixel, is not inactive but instead stuck on a single color and unresponsive to the attached computer’s commands. Users typically find hot pixels more annoying than dead pixels, as the hot pixel (often times white or a bright shade of color) is jarringly obvious on most displays.

Unlike dead pixels, it is sometimes possible to fix a hot pixel by either gently massaging the LCD screen (which in itself is a risky undertaking), or by running a special program that rapidly cycles colors and patterns across the screen in an attempt to “unstick” the color-stuck hot pixel. Both techniques are of limited usefuless, but in situations where the screen is destined for replacement if the hot pixel is not removed, there is little risk in trying DIY repair techniques.
