Overscan support

摘要

Systems, methods, and computer readable media for dynamically setting an executing application's display buffer size are described. To ameliorate display device overscan operations, the size of an executing application's display buffer may be set based on the display device's extent and a display mode. In addition, contents of the executing application's display buffer may be operated on as they are moved to a frame buffer based on the display mode. In one mode, for example, display buffer contents may be scaled before being placed into the frame buffer. In another mode, a black border may be placed around display buffer contents as it is placed into the frame buffer. In yet another mode, display buffer contents may be copied into the frame buffer without further processing.

主权项

1. A non-transitory program storage device, comprising:
computer code to determine a display extent for a display device; computer code to determine the display device overscans; computer code to receive a value indicative of a display mode from an executing application; computer code to send, to the executing application, a display buffer size value equal to the display extent when the display mode is a first mode; computer code to send, to the executing application, a display buffer size value less than the display extent when the display mode is a second mode; and computer code to send, to the executing application, first and second values when the display mode is a third mode, the first value equal to the display extent and the second value less than the display extent.
