Abstract: A system, method and computer readable medium are for managing display devices using manager devices. A communication link is established between display subsystems and manager subsystems. Alarm conditions are detected and reported, and alarm events are triggered within the display devices. The display devices have restricted access to applications, settings, or networks. User-generated media is deleted from the display devices. When idle or when user activity is detected, audiovisual media is presented from the display devices. Powering of the display devices is regulated. Metrics and data associated with the display devices is collected.
