ABSTRACT:
Automated orientation of an image presented by a display, such as a projector, with the orientation of the display simplifies presentation of images generated by an information handling system. A display orientation sensor detects the orientation of a display so that a display orientation module automatically adjusts the orientation of an image presented by the display to align with the display orientation. For example, display orientation is sensed by an accelerometer associated with the display or by determining the attachment point of the display to a support.
