Hot connection and disconnection of an external graphics cable with an information handling system provides automatic selection of an external graphics device or an internal graphics device for presentation of visual information. A graphics state module periodically stores visual information, such as display objects for recreating a display frame, and monitors an external graphics device port, such as a PCI Express port, to detect a change in connection state at the external graphics port. Upon detection of a connection or disconnection at the external graphics port, the graphics state module attempts to initiate graphics devices in a predetermined order and provides the stored visual information for presentation at successfully initiated graphics devices according to the predetermined order.
