While they use different technologies to perform their work, cathode-ray tube and liquid crystal display based video monitors share a common use in presenting game information to players. The video monitor displays the game's visual representation of the game world, its entities, and the game's head up display. Most contemporary video games use a video monitor to deliver a significant amount of a game's information to players.
CRT monitors can used multiple rendering styles to convey information to players, specifically, vector-based display or more traditional color pixel rendering. While these rendering methods differ in technique and feel, they are both used in essentially the same way to transmit information to users.
