Abstract: A projector includes a communication unit or a recording/reproducing unit which obtains content and a controller which displays content in accordance with a first reproduction condition so that an image of quality the same as quality of an image displayed by another projector which displays the content at the same timing is viewed when the communication unit or the recording/reproducing unit obtains content to be displayed by a plurality of projectors and which displays content in accordance with a second reproduction condition which is different from the first reproduction condition when the communication unit or the recording/reproducing unit obtains content to be displayed by the projector.

Abstract: In an image processing apparatus, display on a display device connected to the image processing apparatus is controlled. A change in an image to be displayed on the display device is detected.

Abstract: An information processing apparatus controls image transfer to display an image by projection while making full use of a screen resolution of an external display device without requiring a user to take time and trouble. A server sends a plurality of contents including a first and second content differing in amount of information and associated with each other. To request any one of the contents with the external display device not connected, the server is notified of information for receiving the first content, and to request the content with the external display device connected, the server is not notified of the information. In a case where a state of connection with the external display device changes while the content is displayed, the content is requested from the server again, which determines whether to notify the server of the information in accordance with the state of connection after the change.
