What is Screen Dimming?

Screen dimming is the act of darkening part or all of a display, often to cut distraction or to make a brighter focal area stand out.

Screen dimming reduces the brightness of a region of the display, either uniformly to ease eye strain or selectively to push surrounding content into the background. In presentations, selective dimming pairs with a brighter focal zone so the audiences eye is pulled to the undimmed area.

Screen dimming differs from a magnifier, which changes size, and from a pointer, which marks a location. It is the inverse companion of a spotlight: instead of brightening the focus, it darkens everything else. The two are often combined so the contrast between dim surroundings and a lit area becomes the emphasis.

Dimming fits demos, lectures, and recordings where reducing visual noise helps viewers concentrate. Limelight, a macOS menu-bar app, achieves a similar focusing result through its cursor spotlight (⌃⌥1), which emphasizes the area around your pointer over any app. Limelight also records your screen and exports a finished, cinematic video itself, so that focused look is baked right into the recording.

FAQ

How does screen dimming help a presentation?
