Aspect Ratio

The height to width ratio in PC and TV monitors. In video terms, the display frame can have different rectangular shapes, determined by its recording aspect ratio. Standard television is shown in a ratio of 4:3 (4 units of width to 3 units of height), whereas High Definition displays with a ratio of 16:9. DVD-Video also offers anamorphic and letterbox display formats as options. Not all TV sets offer a 'widescreen' option, and viewing a film using a different aspect ratio shows black bars at the top and the bottom of the screen.
