Abstract
A display system includes a remote controller that includes a communication unit that transmits operation data to a projector, and an operation unit that receives an operation. The projector includes a remote controller light receiving unit that receives the operation data transmitted from the remote controller, a communication I/F unit that communicates with projectors, and a display unit that displays one setting screen selected from among a plurality of setting screens constituting a hierarchical structure in a case where the display unit is selected as an object to be set by the remote controller. The projector transmits an item identifier indicating a hierarchy of the setting screen being currently displayed to the projectors in a case where a switching instruction for switching an object to be set to the projectors is received from the remote controller during the display of the setting screen.
