What is a white dot on a screen characterized by?

A white dot on a screen is characterized by a focused bright point against a dark background. This phenomenon typically occurs when there is a malfunction in the screen’s display technology, such as a stuck pixel or a dead pixel. A stuck pixel may remain bright and present as a white or light-colored dot, particularly visible on darker screens or backgrounds, leading to its distinction as a bright point. In contrast, the other descriptions fail to accurately convey what a white dot represents on a screen, as they involve either darker points or stains that do not align with this visual characteristic.
