A projector includes a selection section configured to select an interface to which an image signal to be displayed by the projector out of the plurality of interfaces is input, a determination section configured to determine whether or not the interface selected is a compliant interface capable of establishing daisy chain connection, and a function control section configured to make the transition of the projector to a state of preventing a daisy chain function from being executed when the interface selected is not the compliant interface, and when the daisy chain function which can be executed in a state in which the projector is coupled to another projector with the daisy chain connection is set available.

Method of controlling display device, and display device

Illuminance in a space where a projector projects an image is accurately detected with failure of the projector due to heat accumulation prevented. The projector includes a window that allows light to pass therethrough, a projection section that projects light through the window to project an image, an illuminance sensor that detects illuminance in a space where the image is projected, an obstacle sensor that has a light emitting section and a light receiving section, the light emitting section emitting second light, the light receiving section receiving the second light, the obstacle sensor detecting an obstacle based on an output from the light receiving section, and a control section that disables the detection of the illuminance during a period for which the light emitting section emits the light.

A projector () which projects a guide image (Pg). A first region above the center of the guide image (Pg) shows a perspective view (D) representing the projector () and a supporting device () supporting the projector (). A second region on the upper right of the guide image (Pg), shows six illustrations (G-G) affixed with numbersto. The six illustrations (G-G) respectively correspond to six adjustment items related to a supporting state of the projector (). The six illustrations (G-G) indicate how a projected image changes when the adjustment items are adjusted. The perspective view (D) is an explanatory diagram for clearly showing the positions of adjustment operation units that adjust the six adjustment items of the supporting device (). In the perspective view (D), the numberstoare affixed near the respective adjustment operation units in balloons.
