Abstract
Systems and methods for providing pre-boot displays at the same time on both a discrete video controller and an embedded video controller of an information handling system in a pre-boot environment, e.g., such that a discrete video controller provides video data for generating a video display during pre-boot operations, while at the same time the embedded video controller also remains active and synchronized with the discrete video controller so that the embedded video controller simultaneously provides video data for generating a video display during pre-boot operations.
