The image output device 100 has a part of its functions restricted. The image output device detects connection with the display device 400 when the display device 400 is mounted. The image output device 100 lifts the restriction on the functions of the device when detecting the connection with the display device 400. The image output device 100 further displays on the display device 400 a screen relating to the restriction-lifted functions. |
