Abstract:
1. A display apparatus for receiving an image signal from a computer and projecting an image depending on the image signal onto a projection surface, said display apparatus comprising: a setting section which sets identification information representative of an aspect ratio of a display of the computer; a storage which stores a plurality of identification information representative of respective aspect ratios; a controller which controls a setting of the identification information in said setting section; an input/output section connected to said computer; a switcher which selectively changes a connection of said setting section to one of said controller and said input/output section; and a key input section which receives a signal input thereto, wherein, when said controller detects a signal input to said key input section for specifying one of said plurality of identification information stored in said storage, said controller instructs said switcher to change the connection of said setting section from said input/output section to the controller, acquires the specified identification information from said storage, newly sets the acquired specific identification information in said setting section through said switcher, and thereafter instructs said switcher to change the connection of said setting section from the controller to said input/output section, wherein said switcher selectively changes between a first state, in which a signal source is connected to a bus, and a second state, in which the signal source is separated from the bus, and wherein the aspect ratio is identified based on the identification information set in the setting section independent of the image signal from the computer.
