An example game system includes a game apparatus and an operating device. The game apparatus acquires operation data from the operating device. Moreover, the game apparatus executes an application and outputs an image generated by the execution of the application to either the operating device or a predetermined display device different from the operating device, or both. When a predetermined operation is performed on the operating device during the execution of the application, a predetermined operation image is displayed on a display unit of the operating device. In a state where the operation image is displayed on the display unit, the game apparatus determines whether or not a control instruction has been provided to control the predetermined display device, on the basis of the operation data. When the control instruction is determined to have been provided, the predetermined display device is controlled in accordance with the control instruction.
