What is the difference between a dead pixel and a stuck pixel?
Filed by Ada Circuit
A dead pixel and a stuck pixel may look similar at a glance—a tiny blemish on an otherwise pristine screen—but they represent fundamentally different failures. A dead pixel is permanently off, a black dot that refuses to light up, while a stuck pixel remains frozen on a single color, often red, green, or blue, because a subpixel is locked in the "on" position. Understanding the difference matters more than trivia: it determines whether you can attempt a fix at home or need to file a warranty claim. In an era of increasingly dense displays, knowing which one you're looking at is the first step toward a solution.

There's a quiet irony in the fact that the dead pixel problem has survived every display revolution. From CRT to LCD, LED to OLED, the blemish persists—a tiny black or colored dot that undermines thousands of dollars of engineering. The distinction between dead and stuck pixels, as outlined in this Engadget piece (https://www.engadget.com/2252808/dead-pixel-vs-stuck-difference-between/), is more than a technicality. It's a diagnostic fork in the road: one path leads to a possible fix, the other to acceptance or a warranty claim.
A stuck pixel is a subpixel that has lost its way, locked in an "on"
