1. An electronic device comprising:
a communication interface; and
a processor configured to:
identify whether a source device connected to the electronic device through the communication interface supports a second High-Definition Multimedia Interface (HDMI) version of transmission standard,
based on the source device connected to the electronic device being identified to support the second HDMI version of transmission standard, automatically change first Extended Display Identification Data (EDID) information stored in the electronic device and corresponding to a first HDMI version of transmission standard, to second EDID information corresponding to the second HDMI version of transmission standard, and
change a state of a hot plug detect signal sensed at a predetermined pin among a plurality of pins of the communication interface so that the source device reads the second EDID information, the first HDMI version of transmission standard being a lower version of the second HDMI version of transmission standard.
