Dead Pixel vs Stuck Pixel: The Complete Guide

They look similar from a couch, but they are different failures with different fixes — and knowing which one you have decides whether a free fixer tool can help.

Dead pixels: the black dots

A dead pixel is a pixel whose power or driving transistor has failed completely. It renders black on a white screen, black on a red screen, black on everything. Nothing you run in software can revive it — the pixel is not confused about what to show, it is disconnected from what to show. Dead pixels are physical damage or manufacturing failure, and the only fixes are warranty replacement or panel swap.

Stuck pixels: the colored dots

A stuck pixel is powered but its sub-pixel driver is latched — typically stuck red, green, or blue on a black screen. Because the hardware is alive, there is a real (if unreliable) software fix: rapid full-field color flashing, which is what our stuck pixel fixer does. Success reports vary wildly — some users revive a pixel in ten minutes, others run the tool overnight for nothing — but the attempt costs nothing and harms nothing.

How to tell which you have

Open our dead pixel test, cycle to pure white: if the dot stays black on white, it is dead. Cycle to pure black: if the dot glows red, green, or blue, it is stuck. Run both colors and note what you see before trying any fix or calling any support line — the answer decides your options.

Warranty reality check

Most manufacturers have a dead-pixel policy with a minimum count before they accept a return (commonly 3–7 dead pixels in a zone). A single dead pixel usually does not qualify, which is exactly why the stuck-vs-dead distinction matters: a revivable stuck pixel you fix at home beats a dead pixel that fails the warranty threshold.

Frequently asked questions

Can a dead pixel spread?

No. Pixels do not spread; what spreads is a crack or pressure damage, which is a different failure mode.

Do dead pixels appear over time?

Yes, occasionally — usually as isolated failures with age, not in clusters unless the panel was damaged.
