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.
