1. A display device comprising:
a source driver; and
a timing controller,
the source driver and the timing controller performing data communication through serial transmission,
the display device further comprising a storage unit configured to store information about each of a plurality of standards that are different from each other, the standard defining a protocol for specific serial transmission,
wherein the timing controller
selects one standard from among the plurality of standards,
performs first determination that is determination on the selected standard to determine whether to receive a lock signal from the source driver within a predetermined period after training pattern data compatible with the selected standard is output to the source driver, and
outputs an image signal of the protocol of the selected standard to the source driver when a result of the first determination is positive.
