1. A display apparatus comprising:
a display panel comprising a first region and a second region symmetrical to the first region;
a main controller configured to process source data and to generate an image signal;
a timing controller configured to generate a driving signal for driving the display panel based on the image signal; and
a cable connected to the display panel and configured to transmit the driving signal to the display panel,
wherein the main controller is configured to:
transmit, to the timing controller, a pattern image signal for displaying a pattern image on the first region and the second region in a sequential manner; and
determine a connection state of the cable based on (i) a first current value, which is output from the timing controller based on the pattern image displayed in the first region and (ii) a second current value, which is output from the timing controller based on the pattern image displayed in the second region.
