Abstract: A redundant display system includes a communication network, display devices, first and second display nodes, a control node, a monitoring node, and a system node. Display devices each include first and second display inputs. First display nodes include first display outputs, each connected to a first display input to display digital content on display devices and can be assigned the role of main or redundant display node. Second display nodes include second display outputs, each connected to a second display input to display digital content on display devices and can be assigned the role of main or redundant display node. The control node sends digital content to the display nodes. The monitoring node collects operational information of the display nodes and generates alerts if the operational information indicates a failure. The system node receives alerts from the monitoring node and reassigns roles of the display nodes based on the alerts.
