Abstract
A display apparatus and a control method thereof are provided. The display apparatus is coupled to a video signal supply source through at least one connector. The display apparatus includes: a main storage unit which stores extended display identification data (EDID) therein corresponding to the at least one connector; a temporary storage unit which loads the EDID thereto from the main storage unit; and a controller which loads the EDID stored in the main storage unit to the temporary storage unit if power is supplied, and controls to transmit the EDID corresponding to an EDID requesting signal, among the EDID loaded to the temporary storage unit, through the at least one connector if the EDID requesting signal is received through the at least one connector.
Claims16
A display apparatus capable of being coupled to plurality of external video signal supply sources through a plurality of connectors, the display apparatus comprising:
- a storage unit at the display apparatus which stores a plurality of extended display identification data units (EDIDs) therein corresponding to the plurality of connectors, respectively;
- a temporary storage unit at the display apparatus which stores one or more loaded EDIDs thereto from the storage unit;
- and
- a controller configured to receive an EDID requesting signal from an external video signal source through one of the plurality of connectors and to transmit an EDID corresponding to the one of the plurality of connectors to the external video signal source in response to the EDID requesting signal.
A control method of a display apparatus which is capable of being coupled to a video signal supply source through a plurality of connectors, the control method comprising:
- loading a plurality of extended display identification data (EDIDs) corresponding to the plurality of connectors from a main storage unit at the display apparatus to the temporary storage unit at the display apparatus;
- and
- transmitting an EDID corresponding to an EDID requesting signal from the display apparatus to an external video signal supply source coupled to the display apparatus through a corresponding connector among the one or more EDIDs loaded to the temporary storage unit, from the display apparatus to the video signal supply source through the corresponding connector if the EDID requesting signal is transmitted from the external video signal source through the corresponding connector.
