Image display device and method of changing first information with second EDID information wherein each EDID information is stored on different storage units
First Claim
1. An image display device which is connectable to a source providing device, the image display device comprising:
- a first storage unit which stores extended display identification data (EDID) information to be provided to the source providing device;
a second storage unit which stores at least one version of the EDID information which is different from the EDID information stored in the first storage unit; and
a control unit which replaces the EDID information stored in the first storage unit with the different version of the EDID information stored in the second storage unit such that the different version of the EDID information is stored in the first storage unit if an EDID information change request signal is input.

Abstract
An image display device and method of changing extended display identification data (EDID) information includes a first storage unit which stores extended display identification data (EDID) information to be provided to the source providing device, a second storage unit which stores at least one version of the EDID information which is different from the EDID information stored in the first storage unit, and a control unit which replaces the EDID information stored in the first storage unit with the different version of the EDID information stored in the second storage unit if an EDID information change request signal is input. Accordingly, compatibility of the EDID information between the source providing device and the image display device can be maintained.

28. An image display device connectable to an image source device, comprising:
-
a storage unit to store extended display identification data (EDID) information; and a controller to receive a change request from the image source device, and to replace the stored EDID information with a different version of EDID information stored in a second storage unit according to the change request that is based on at least one different version of EDID stored in the second storage unit such that the at least one different version of EDID information is stored in the first storage unit.

29. An image display device which is connectable to a source providing device, the image display device comprising:
-
a first storage unit which stores extended display identification data (EDID) information to be provided to the source providing device; a user interface unit that lists of the at least one EDID information stored in a second storage unit that stores at least one version of the EDID information which is different from the EDID information stored in the first storage unit; and a control unit which replaces the EDID information stored in the first storage unit with the different version of the EDID information stored in the second storage unit such that the different version of the EDID information is stored in the first storage unit in response to a selection of the at least one different version of the EDID included in the list of the user interface unit.
