A method and system for preventing a local display device from, displaying data generated by a remote computing device is described. The system includes a local agent for facilitating a remote session; an operating system generating a request to enable a display device controlled by a display adapter; and a filter executing in a driver and in communication with the local agent, the filter intercepting the request generated by the operating system. The filter transmits the request to the local agent when a remote user is active or to the display adapter when the remote user is inactive. The filter will transmits a signal to the operating system that the display adapter has enabled the display device when the filter transmits the request to at least one of the local agent and the display adapter.
