发明名称 NOTIFYING A GRAPHICS SUBSYSTEM OF A PHYSICAL CHANGE AT A DISPLAY DEVICE
摘要 When a physical change (e.g. a change in screen orientation) is detected at a display device that is attached to a graphics subsystem of a host device and on which images are currently being displayed, a hot plug detect signal may be provided to the graphics subsystem. In response, the graphics subsystem may adjust its processing of images to account for the physical change (e.g. the image may be rotated). The display device may communicate data representative of the physical change to the graphics subsystem. The graphics subsystem may use this data to determine how its processing of images should be adjusted. The data may be communicated over an I2C bus regardless of whether a hot plug detect signal is provided.
