16:9
Refers to a wide screen. The 16:9 is the ratio of width to height of the screen on a high-definition TV set (HDTV). Also expressed as the ratio 1.78:1, a 16:9 screen provides a wider rectangle compared to the 4:3 ratio of standard TV sets and most computer monitors. However, 16:9 is not as wide as the screens in major movie theaters (see aspect ratio for comparison). Watching many movies in their original format on a 16:9 screen will still result in letterbox viewing. See letterbox and HDTV.
