One of a video source device and a video sink device may: (a) deactivate a video processing function at the one device and send a command for causing the other of the video source device and the video sink device to activate the video processing function; (b) activate the video processing function at the one device and send a command for causing the other device to deactivate the video processing function; and (c) based on user input indicating whether (a) or (b) resulted in a preferred video image, effect (a) or (b). The one device may receive an indication of video processing functions of which the other device is capable, such that (a), (b) and (c) may be performed for each indicated video processing function of which the one device is also capable. A user interface including at least one selectable control for indicating whether a video image resulting from (a) or (b) is preferred may be displayed.
