Abstract: A control method for a projector includes coupling a projector to another projector, transmitting first instruction information representing a start of setting of stack projection using the projector and the other projector to the other projector by the projector, setting a first projection range indicating a range in which the projector projects an image for the stack projection, and transmitting second instruction information representing adjustment to make a second projection range indicating a range in which the other projector projects an image coincide with the first projection range to the other projector by the projector.

Abstract: A method for controlling a projector, the method comprising: determining, when the projector having an RF tag is started up, whether a setting that permits a process of reading out setting information stored in the RF tag and configuring a setting on the projector based on the setting information is configured or not; determining whether a password requested to be inputted to an information processing device is at an initial value or not, when the setting information is written into the RF tag from the information processing device; and notifying a user of a warning message when it is determined that the setting that permits the process is configured and it is determined that the password is at the initial value.
