Abstract
A display apparatus include a connector, a readable/writable EDID storage to store EDID, and a controller to control the EDID storage to be write-protected from error data transmitted from a computer through the connector. With this configuration, the display apparatus and a method of controlling the same can prevent error data from being stored in an EDID storage.
Claims25
A display apparatus to communicate with a computer, comprising:
- a connector to generate a determining signal;
- a readable/writable EDID storage to store EDID;
- and
- a controller to control the EDID storage to be write-protected from error data transmitted from the computer based on the determining signal of the connector,
- wherein the EDID storage comprises a write-protect (WP) port, and the controller comprises a microcomputer to transmit an enable signal or a disable signal to the WP port according to the determining signal of the connector.
A method of controlling a display apparatus comprising a connector to generate a determining signal and a readable/writable EDID storage to store EDID, the method comprising:
- controlling the EDID storage to be write-protected from error data transmitted from a computer based on the determining signal of the connector,
- wherein the controlling of the EDID storage comprises:
- allowing the connector to output the determining signal according to whether the connector is selectively connected with a video card of the computer or an EDID storage jig to store the EDID;
- and
- controlling the EDID storage to be write-protected from the error data when determined that the video card is connected, and controlling the EDID storage to store the EDID transmitted from the EDID storage jig when determined that the EDID storage jig is connected, on the basis of the determining signal of the connector.
A control unit of a readable/writeable storage unit to store data usable with a display apparatus, comprising:
- a connector to generate a signal;
- and
- a controller to control the readable/writable storage unit to be write-protected based on the signal received from the connector.
