Abstract
Systems and methods for utilizing multiple graphics processing units for controlling presentations on a display are presented. In one embodiment, a dual graphics processing system includes a first graphics processing unit for processing graphics information; a second graphics processing unit for processing graphics information; a component for synchronizing transmission of display component information from the first graphics processing unit and the second graphics processing unit and a component for controlling switching between said first graphics processing unit and said second graphics processing unit. In one embodiment, the component for synchronizing transmission of display component information adjusts (e.g., delays, speeds up, etc.) the occurrence or duration of a corresponding graphics presentation characteristic (e.g., end of frame, end of line, vertical blanking period, horizontal blanking period, etc.) in signals from multiple graphics processing units.
