A system for establishing a remote desktop connection between a client projector and a host computer, the client projector and the host computer being connected by a network. A private remote desktop service virtual channel is established between the host computer and the client projector. In the client projector, a processor initiates a remote desktop connection process, and completes a remote desktop connection to the host computer. The client projector receives keyboard and mouse events from the host computer across the private remote desktop service virtual channel. The keyboard or mouse events received by the client projector are injected into an operating system of the client projector. They are interpreted by a client application remote desktop connection as a valid input device event, and forwarded to the host computer to actuate a graphical user interface of a remote desktop session.
