The electronic device receiving content from an external device includes a memory configured to include a first HDMI version of Extended Display Identification Data (EDID) information, a second HDMI version of EDID information, the second HDMI version being an upgraded version of the first HDMI version and, at least one resolution information supportable in the electronic device other than the first HDMI version of EDID information, an external interface configured to communicate with the external device and a processor configured to cause the second HDMI version of EDID information to not be read by the external device, to cause the EDID information of the first HDMI version among the EDID information to be read by the external device, and to cause the at least one resolution information to be read by the external device. ## Claims ### Claim 1 An electronic device configured to receive content from an external device, the electronic device comprising: a memory configured to store first resolution-related information for a first version of High-Definition Multimedia Interface (HDMI); second resolution-related information for a second version of HDMI, the second HDMI version being an upgraded version of the first HDMI version; and third resolution-related information for the second version of HDMI, wherein the first resolution-related information is stored in a first Vendor-Specific Data Block (VSDB) of the memory, the second resolution-related information is stored in a second VSDB of the memory, and the third information is stored in an area of the memory other than the first VSDB and the second VSDB; an HDMI port configured for communication with the external device; and a processor configured to: determine whether a setting relating to communication with the external device via the HDMI port is a first setting or a second setting different from the first setting; based on the setting relating to communication with the external device via the HDMI port being the first setting, control reading of the first VSDB and the third resolution-related information by the external device; based on the setting relating to communication with the external device via the HDMI port being the second setting, control reading of the first VSDB, the second VSDB and the third resolution-related information by the external device; and receiving, through the HDMI port, content from the external device. ### Claim 2 (depends on 1) The electronic device of claim 1, wherein the setting relating to communication with the external device via the HDMI port comprises a menu setting. ### Claim 3 (depends on 2) The electronic device of claim 2, wherein the processor is configured to, based on the setting relating to communication with the external device via the HDMI port being the first setting and an input of content of the second HDMI version being received from the external device, automatically activate the menu or provide a UI for enabling activating of the menu. ### Claim 4 (depends on 2) The electronic device of claim 2, wherein the processor is configured to, based on Source Product Description (SPD) information with a predetermined bit being activated being received from the external device, automatically activate the menu or provide a UI for enabling activating of the menu. ### Claim 5 (depends on 1) The electronic device of claim 1, wherein the third resolution-related information comprises at least one bit of the area of the memory, and at least one other bit of the area of the memory comprises color information for color supportable in addition to color supportable in the first HDMI version. ### Claim 6 An electronic device providing content, the electronic device comprising: a High-Definition Multimedia Interface (HDMI) port configured for communication with an external device, the external device storing first resolution-related information for a first version of HDMI; second resolution-related information for a second version of HDMI, the second HDMI version being an upgraded version of the first HDMI version; and third information; and a processor configured to: obtain identification information of the external device; identify that the third information comprises resolution-related information for the second HDMI version based on the identification information; in response to the first resolution-related information and the third information being obtained from the external device, providing the content to the external device based on the third information; in response to the first resolution-related information, the second resolution-related information and the third information being obtained from the external device, providing the content to the external device based on at least one of the second resolution-related information and the third information, wherein the first resolution-related information is obtained from a first Vendor-Specific Data Block (VSDB) of a memory included in the external device, the second resolution-related information is obtained from a second VSDB of the memory, and the third information is obtained from an area of the memory other than the first VSDB and the second VSDB. ### Claim 7 (depends on 6) The electronic device of claim 6, wherein the processor is configured to control obtaining the third information from the area of the memory of the external device assigned to an ID Serial Number according to HDMI standard. ### Claim 8 A method of controlling an electronic device which communicates with an external device through a High-Definition Multimedia Interface (HDMI) port, the external device stores, in a memory, first resolution-related information for a first version of HDMI; second resolution-related information for a second version of HDMI, the second HDMI version being an upgraded version of the first HDMI version; and third information, wherein the first resolution-related information is stored in a first Vendor-Specific Data Block (VSDB) of the memory, the second resolution-related information is stored in a second VSDB of the memory, and the third information is stored in an area of the memory other than the first VSDB and the second VSDB, the method comprising: obtaining identification information of the external device; identifying that the third information comprises resolution-related information for the second HDMI version based on the identification information; in response to the first resolution-related information and the third information being obtained from the external device, providing content to the external device based on the third information; and in response to the first resolution-related information, the second resolution-related information and the third information being obtained from the external device, providing the content to the external device based on at least one of the second resolution-related information and the third information, wherein the first resolution-related information is obtained from the first Vendor-Specific Data Block (VSDB) of the memory, the second resolution-related information is obtained from the second VSDB of the memory, and the third information is obtained from the area of the memory other than the first VSDB and the second VSDB. ### Claim 9 (depends on 8) The method of claim 8, further comprising: automatically enabling activating, based on the first resolution-related information and the third information being obtained from the external device, a menu of the external device related to the HDMI port or transmitting a control signal to the external device to provide a UI for enabling activating of the menu.
