Monitors designed to display electronic images with a definition higher than the standard-definition television, either in real time as they are obtained using a video camera or from a video or digital versatile disk player, a television system, or from a digital computer or computerized network. These monitors typically include electronic circuitry to process the video signal and a screen (e.g., liquid crystal or plasma display, projection sets) to display the image. Monitors used to display high-definition commercial television (HDTV) are usually standardized to 720 (720 pixels of vertical resolution, i.e., 1280 x 720 pixels) or full high-definition (1080 pixels of vertical resolution, i.e., 1920 x 1080 pixels). High-definition video monitors may be used for many purposes, including monitoring patient activity and displaying non-diagnostic images during surgical, endoscopic, and fluoroscopic procedures.
