In the past, you needed a screen saver, a continually moving display, to protect your monitor from burn in, which occurs when the same display remains on the screen for extended periods of time and becomes part of the screen.

When you leave your computer idle for a specified wait time, a screen saver displays a continuous scene, such as an aquarium, until you move your mouse to stop it.
