1. A source device comprising:
a wireless communication module including a communication circuit;
a memory; and
at least one processor
configured to:
transmit an expanded screen, generated by the source device for display on a sink device connected to the source device, to the sink device through the wireless communication module, the expanded screen being a screen for display on a display of the sink device in association with a first screen displayed on a display of the source device in an expansion mode;
identify a screen focused by an input device connected to the source device among the first screen and a second screen displayed on the display of the sink device; and
switch between first and second schemes for displaying an input event generated by the input device, based on at least one of a display mode of the sink device or whether the focused screen is the first screen or the second screen,
wherein, in the first scheme, the input event is displayed on the first screen and, in the second scheme, the source device transmits a control signal to the sink device to display the input event, and
wherein, when the focused screen is the second screen and when the display mode of the sink device is a reduction mode in which the expanded screen is reduced on the second screen or a minimization mode in which the expanded screen is minimized on the second screen, at least one processor is configured to switch the processing scheme from the first scheme to the second scheme.
