A method of operating a mobile device in relation to an external display device, the method comprising: detecting, by the mobile device, that the external display device is available for communications with, or has entered into communications with, the mobile device; starting execution, on at least one processing portion of the mobile device, of at least one intermediary software component serving to interface between the mobile device operating system and the touchscreen display software components when the mobile devices is in an external display mode of operation, where the at least one intermediary software component interfaces with each of a mobile device operating system executed on the mobile device, a touchscreen display via one or more touchscreen display software components, and the external display device; receiving one or more user inputs at the touchscreen of the mobile device; providing, by the one or more intermediary software components, one or more input signals indicative of the user inputs to the mobile device operating system; generating at the mobile device operating system, in response to receiving the one or more input signals, one or more first imaging signals suitable for receipt by an output device of the mobile device; processing, by the one or more intermediary software components, the one or more first imaging signals so as to produce second imaging signals indicative of a first image portion representative of a mobile device status or operational condition; and sending, by the one or more intermediary software components, external display driving signals identical to or based at least partly upon the second imaging signals for receipt by the external display device, whereby the external display device displays an overall image including the first image portion. detecting, by the mobile device, that the external display device is available for communications with, or has entered into communications with, the mobile device; starting execution, on at least one processing portion of the mobile device, of at least one intermediary software component serving to interface between the mobile device operating system and the touchscreen display software components when the mobile devices is in an external display mode of operation, where the at least one intermediary software component interfaces with each of a mobile device operating system executed on the mobile device, a touchscreen display via one or more touchscreen display software components, and the external display device; receiving one or more user inputs at the touchscreen of the mobile device; providing, by the one or more intermediary software components, one or more input signals indicative of the user inputs to the mobile device operating system; generating at the mobile device operating system, in response to receiving the one or more input signals, one or more first imaging signals suitable for receipt by an output device of the mobile device; processing, by the one or more intermediary software components, the one or more first imaging signals so as to produce second imaging signals indicative of a first image portion representative of a mobile device status or operational condition; and sending, by the one or more intermediary software components, external display driving signals identical to or based at least partly upon the second imaging signals for receipt by the external display device, whereby the external display device displays an overall image including the first image portion.
