A computer system with an architecture and protocol that facilitate ready integration with an auxiliary display device. The auxiliary display device is coupled to the computer system over a transport, such as Bluetooth, USB or TCP/IP. From an application level gadget, control of the display device is through a programming interface to a platform component. The platform component interfaces with a device driver, which has two components. One component is common and can be used with any auxiliary display device supporting the protocol, regardless of which transport is used. The second component is transport specific. The second component processes data streams representing packets according to the protocol, conveying the packets as data in accordance with the format of the transport. The second component may be simple because it is not required to perform any processing specifically associated with the display functions or protocol.
