Split screen is a display technique in computer graphics that consists of dividing graphics and/or text into non-movable adjacent parts, typically two or four rectangular areas. This is done in order to allow the simultaneous presentation of (usually) related graphical and textual information on a computer display. Split screen differs from windowing systems in that the latter allows overlapping and freely movable parts of the screen (the "windows") to present related as well as unrelated application data to the user, while the former more strictly conforms to the description given in the above paragraph.

A split screen for four players, all playing Call of Duty simultaneously on the same screen

In its most easily-understood form, a split screen for a two-player video game is an audiovisual output device (usually a standard television for video game consoles) where the display has been divided into two equally-sized areas so that the players can explore different areas simultaneously without being close to each other. This has historically been particularly popular on consoles, which until recently did not have access to the Internet or any other network.

The only alternative for multiplayer games would be to have a separate television set for each player - this would require the console itself to have separate output wires with different signals for each television. Although 82% of homes in the United States have more than one television[1] (and this figure would have been even lower [citation needed] during the rise of consoles during the 1980s-1990s), very few people would have more than one in the same room[citation needed]. Therefore, games consoles were not designed to offer this facility for multiplayer games. This article does not cite any references or sources. ... For the band, see 1990s (band). ...


One specific issue with split-screen multiplayer is screen peeking, where one player examines opposing players' screens to gain a sometimes unfair advantage. Some console games have gone to the length of supporting tiny auxiliary displays in each player's controller as a counter-measure. Example of a split screen multiplayer game of Call of Duty. ...
