Widescreen

Widescreen images are displayed within a set of aspect ratios (relationship of image width to height) used in film, television and computer screens. In film, a widescreen film is any film image with a width-to-height aspect ratio greater than 4:3 (1.33:1). For TV, the original screen ratio for broadcasts was in 4:3 (1.33:1). Largely between the 1990s and early 2000s A.D., at varying paces in different countries, 16:9 (e.g. 1920x1080p 60p) widescreen displays came into increasingly common use by High Definitions. With computer displays, aspect ratios others than 4:3 (e.g. 1920x1440) are also referred to as "widescreen". "Widescreen" computer displays were previously made in a 16:10 aspect ratio (e.g. 1920x1200), but nowdays are they usually 16:9 (e.g. 1920x1080).
