Abstract: One embodiment provides a graphics processor device that includes circuitry configured to detect a connection of a second display device to a display subsystem of the graphics processor while a first display device of the graphics subsystem is active, write pre-determined pixel data to a reserved portion of memory associated with the display subsystem, configure timings for the second display device while resources allocated to the first display device remain available to the first display device, display the pre-determined pixel data from the reserved portion of the memory on the second display device during reallocation of the resources of the display subsystem to enable output the framebuffer data to the second display device, and transition the second display device from the display of the pixel data in the reserved portion of the memory to the display of the framebuffer data after resources of the display subsystem are reallocated.

Abstract: Disclosed herein is a display controller and display controller techniques to self-refresh a non-self-refresh display. The display controller can be configured to determine when display data is static. During periods where display data is static, the display controller can cache display data output in device memory and “refresh” the display data using the cached display data output. A display controller can receive a number of display data elements to be overlaid. The display controller can blend the display data elements into blended display data and can send the blended display data to a display. The display controller can determine whether the display data elements are static. The display controller can cache the blended display data based on determining that the display data elements are static and can send the cached blended display data to the display every refresh while the display data elements are no longer static.
