Even when the terminal device 2 is connected to the projector 1 while the projected video signal is being projected, one of the modes may be selected as described above.

In the embodiment described above, the terminal device 2 that has transmitted the connection request displays the screen of FIG. 7 or FIG. 8, but is not limited to this configuration, and may display another menu screen. For example, the menu screen displayed in step SA4 may be the menu screen illustrated in FIG. 9, and the menu screen displayed in step SA8 may be the menu screen illustrated in FIG. The menu screen shown in FIG. 9 is different from the first menu screen in that it has a “select later” button B5, and the menu screen shown in FIG. 10 is different in that it has a “select later” button B6. Different from 2 menu screen.
When the operation of tapping the button B5 is performed in a state where the menu screen shown in FIG. 9 is displayed, the terminal device 2 selects the third mode that is neither the first mode nor the second mode. In addition, the terminal device 2 selects the third mode even when an operation of tapping the button B5 is performed in a state where the menu screen illustrated in FIG. 10 is displayed.
When the terminal device 2 selects the third mode, the terminal device 2 does not transmit the video signal to the projector 1 while maintaining the connection with the projector 1, and does not receive the video signal transmitted from the projector 1. That is, the terminal device 2 is in a mode in which no image is projected by the projector 1 and the image projected by the projector 1 is not displayed (shared). The terminal device 2 that has selected the third mode can display the video stored in the storage unit 22 on the touch panel 23.
Note that the terminal device 2 connected to the projector 1 and selecting the third mode displays the menu screen of FIG. 9 or FIG. 10 in accordance with a user operation. When the user performs an operation of tapping the button B1 or the button B3 on the displayed menu screen, the terminal device 2 selects a mode corresponding to the tapped button, and the projector 1 uses the mode corresponding to the selected mode. The image is projected and the image projected by the projector 1 is displayed on the touch panel 23.
