In one embodiment, video content displayed across a plurality of display devices is synchronized by first obtaining a first set of VSYNC timestamps for a display controller of a first video display device and a second set of VSYNC timestamps for a display controller of a second video display device. An adjustment factor is determined based on a comparison of the first and second VSYNC timestamps, and an adjusted VSYNC period for the display controller of the second video display device is programmed based on the determined adjustment factor. After a predetermined number of VSYNC cycles, the display controller of the second video display device reverts back to an original VSYNC period.

Multi-display video synchronization

An apparatus and method are described for implementing memory management in a graphics processing system. For example, one embodiment of an apparatus comprises: a first plurality of graphics processing resources to execute graphics commands and process graphics data; a first memory management unit (MMU) to communicatively couple the first plurality of graphics processing resources to a system-level MMU to access a system memory; a second plurality of graphics processing resources to execute graphics commands and process graphics data; a second MMU to communicatively couple the second plurality of graphics processing resources to the first MMU; wherein the first MMU is configured as a master MMU having a direct connection to the system-level MMU and the second MMU comprises a slave MMU configured to send memory transactions to the first MMU, the first MMU either servicing a memory transaction or sending the memory transaction to the system-level MMU on behalf of the second MMU.
