Abstract

An electronic device and method include receiving one of a plurality of projection-mode triggers, each projection-mode trigger having associated projection-mode display parameters, based on the received projection-mode trigger, initiating a projection mode at the electronic device, receiving, from an application, content information for display on a display of the electronic device, altering the content information based on the display parameters associated with the received one of the plurality of projection-mode triggers to generate altered content information, and displaying the altered content information on the display of the electronic device.
