📝 Stuck Pixel vs Dead Pixel: What Is the Difference
August 13, 2026
Dead pixels and stuck pixels are often confused, but they are different problems.
Dead pixel
No power reaches the sub-pixels at all, so the point stays black regardless of what color the screen is showing. This is usually permanent.
Stuck pixel
One sub-pixel (red, green, or blue) stays permanently on, so the point glows in the same color (for example, always red). In some cases this can fade on its own over time.
How do you tell them apart?
A bright colored dot against a black background is more likely a stuck pixel; a point that never reacts to any color is more likely a dead pixel.
