A stuck pixel remains illuminated, displaying a constant color like red, green, or blue, while a dead pixel is permanently off and appears black. Stuck pixels often have troubleshooting options and can sometimes be repaired, whereas dead pixels are non-functional and typically require a screen replacement or tolerance. Specialized websites and applications, such as Dead Pixel Buddy and JScreenFix, can assist in identifying and potentially fixing stuck pixels, but dead pixels are generally considered unrecoverable.
