Described is a mechanism by which application programs (or plug-ins) and an auxiliary service adjust the output and / or data available for output on an auxiliary device based on changes detected in the current context of the auxiliary display. Context sensors detect and report changes in context, whereby some action is taken with respect to what information is displayed or can be displayed on the auxiliary display device. Examples of context data that can change include the physical location of the display, detected movement or motion data, presence of a particular user or others, power state, network connectivity status, privacy status and so forth. The auxiliary device can have context as to its position relative to the main display. Information sensitivity levels may be used to specify whether an application program's data can be displayed, based on the perceived sensitivity of the information and the user's current context.
