A Display Manager is placed between the Master Gaming Controller and its Main Game Display and any Secondary Display and between the Player Tracking Unit connected to the casino system network (e.g., player tracking device) and its System display. The Display Manager receives one or more video signals from the Master Gaming Controller and one or more video signals from the system device and displays one or multiple video signals on one or more shared displays. One of the video signals may be presented alone on one of the displays, with the other signal absent from that shared display, or multiple signals may be simultaneously displayed on one of the shared displays. The screen may be split between multiple signals, or one or more signals may overlay one or more background signals. The overlaid signals may completely obscure the background signals, or they may provide a level of transparency by allowing the background signal to be partially or completely visible. Also, the overlaid signal may provide different levels of transparency in different areas of the display, effectively superimposing an image on top of the background signal. The Display Manager receives commands from a device, directing it how to split, overlay, superimpose, and otherwise share the display among the video input signals.
