Abstract
An example source device includes a wireless communication module, a memory, and a processor. The processor may transmit an expanded screen, generated by the source device to be displayed on a sink device connected to the source device, to the sink device through the wireless communication module. The expanded screen may be a screen displayed on a display of the sink device in association with a first screen displayed on a display of the source device to expand a task space of the source device. The source device may identify a screen focused by an input device connected to the source device among the first screen displayed on the display of the source device and a second screen displayed on the display of the sink device. The source device may switch a processing scheme to process 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.
