Abstract

Systems, methods, and devices are provided for automatically configuring a display layout for a slide presentation to allow a presenter to seamlessly perform effective, professional slide presentation even in unfamiliar locales. A method for doing so may involve receiving connected display information that describes the electronic displays currently connected to the electronic device. When the connected display information indicates that multiple electronic displays are currently connected, the processor of the electronic device may automatically choose, without explicit user assignment, a main presentation display and one or more presenter displays. The main presentation display may display a slide presentation from among the multiple electronic displays, while the presenter displays may display information other than only the slide presentation to aid the presenter. The main presentation display and the presenter displays may be chosen based at least in part on the connected display information.
