ABSTRACT:
A computing device includes first and second graphics adapters. A graphics processor of the first graphics adapter acts as a master graphics processor, while a second graphics adapter acts as a slave. The master graphics processor renders graphics to be displayed on multiple separate displays within memory of the first graphics adapter. Images to be displayed on one of the displays are transferred to memory used by the second graphics adapter. The display interface of the second graphics adapter presents images within the memory of the second graphics adapter on at least one of the multiple displays. In this way, device electronics forming the display interface, as well as ports of the second adapter, acting as a slave, may be utilized. In one embodiment, an application creates a single larger image, rendered within the memory of the first graphics adapter. The larger image is then presented as the first and second smaller images on the multiple displays. In this way, an end user sees the multiple images as a single large image across the multiple displays.
