PROBLEM TO BE SOLVED: To stabilize operation when plural projectors are used.SOLUTION: A projector comprises: plural transmitters for transmitting signals; a receiver for receiving a signal transmitted from another projector; and a controller which on the basis of the signal received from mentioned another projector by the receiver, synchronizes the signal between the device and the mentioned another projector. The controller comprises: a state determination unit which determines whether synchronization with mentioned another projector is stable or not; and a number determination unit which determines the number of transmitters to be used among the plural transmitters, on the basis of a determination result obtained by the state determination unit. |
