Abstract: The subject matter of this specification can be embodied in, among other things, a method that includes transmitting content to a location for presentation across a plurality of display devices that each present a portion of the content. The method includes receiving an indication that a first portion of the content managed by a first computing device is unable to be presented on a first display device. The method also includes transmitting a command to display the first portion on a second display device (where the second display device is configured to present a second portion of the content) if the received indication specifies that the first display device experienced a failure or transmitting a command that the first portion be displayed on the first display device using a second computing device if the received indication specifies that the first computing device experienced a failure.
