A mobile settings control device (MSCD) presents a user interface (UI) enabling a user to establish display settings for a display associated with an audio video display device (AVDD) with which the MSCD communicates. Before and after adjustment screen shots may be presented full screen and toggled between on either the AVDD or MSCD, or split screens of before and after adjustment screen shots can be presented side by side on the AVDD or MSCD.
