Abstract
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.
Claims20
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 version of transmission standard,
- based on the source device connected to the electronic device being identified to support the second version of transmission standard, change first Extended Display Identification Data (EDID) information stored in the electronic device and corresponding to a first version of transmission standard to second EDID information corresponding to the second 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 version of transmission standard being different from the second version of transmission standard.
A method for controlling an electronic device, the method comprising:
- identifying whether a source device connected to the electronic device through a communication interface supports a second version of transmission standard;
- based on the source device connected to the electronic device being identified to support the second version of transmission standard, changing first Extended Display Identification Data (EDID) information stored in the electronic device and corresponding to a first version of transmission standard to second EDID information corresponding to the second version of transmission standard;
- changing 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 version of transmission standard being different from the second version of transmission standard.
A non-transitory computer readable medium having stored thereon one or more instructions which, when executed by a processor of an electronic device, causes the electronic device to perform operations including:
- identifying whether a source device connected to the electronic device through a communication interface of the electronic device supports a second version of transmission standard;
- based on the source device being identified to support the second version of transmission standard, changing first Extended Display Identification Data (EDID) information stored in the electronic device and corresponding to a first version of transmission standard to second EDID information corresponding to the second version of transmission standard;
- changing 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 version of transmission standard being different from the second version of transmission standard.
