Implementing Wireless Displays That Handle Rotation and/or Portrait-First Sinks

摘要

Rotation between landscape and portrait modes or vice versa may be supported in wireless display interfaces coupled to a platform by having the platform sense rotation change in the platform or in the display. This enables counter rotation of the frame buffer or rotated rendering of the content to ensure that content is presented upright to the end user.
