Explanation

Dead pixels are LCD pixels that have permanently failed and no longer emit light, appearing as small dark (black) dots that remain fixed in the same position regardless of what is displayed on screen. This matches the description exactly. A distorted image (A) typically involves warping or stretching of visuals, not fixed dots. Pixelation (C) refers to images appearing blocky or low-resolution due to scaling, not fixed dark spots. An incorrect color palette (D) would cause color rendering issues across the entire display, not isolated dots.
