Abstract
A method and system in a computer having a primary video controller for dynamically selecting an alternative video controller present within the computer. Initially, a diagnostic is performed to determine if alternative video controllers are connected to the computer system. A user is thereafter prompted to select an alternative video controller, if at least one alternative video controller is detected. The primary video controller is then temporarily disabled, in response to a selection of an alternative video controller. The alternative video controller is then automatically designated as the primary video controller, in response to the disabling of the primary video controller, such that the alternative video controller may be temporarily utilized as a primary video controller without altering internal computer system hardware settings or power cycling the computer system. The primary video controller may be implemented initially as an on-board video controller, while the alternative video controllers may be connected to the computer via adapter peripheral cards and slots.
