A detection circuit indicates when a source device is coupled to a sink. An interface circuit separately interfaces with the plurality of source devices and permits display identification data associated with an interfaced source device to be sent from the memory unit to the interfaced source device. A monitoring unit monitors communications between the plurality of source devices and a memory unit and generates a signal for the plurality of source devices upon identifying that the memory unit is available for storing display identification data that is associated with a remaining source device of the plurality of source devices. The signal is communicated to the control unit to cause the control unit to update the memory unit with the display identification data that is associated with the remaining source device(s). A power detection circuit powers the sink via power from a source device(s) in a low-power mode.
