An electronic device includes a memory; a communication interface; and a processor. The processor is configured to, based on a source device connected through the communication interface being identified to support a first version of transmission standard, convert first Extended Display Identification Data (EDID) information, which is stored in the memory and corresponds to a second version of transmission standard, to second EDID information corresponding to the first version of transmission standard, and change a state of a hot plug detect signal related to the communication interface so that the source device reads EDID information.
