Abstract
A display apparatus includes: a display; an input interface; and a processor in connection with the display and the input interface and configured to: upon detecting access of a first power amplifier device, output a high-level Hotplug signal at a Hotplug port of the display apparatus; monitor whether a common-mode data packet from the first power amplifier device is received within a first preset duration; in response to the common-mode data packet being received within the first preset duration, send a heartbeat packet to the first power amplifier device, and monitor whether a heartbeat response is received within a second preset duration; in response to the heartbeat response being received within the second preset duration, determine that the first power amplifier device supports e-ARC function; and in response to the heartbeat response being not received within the second preset duration, determine that the first power amplifier device supports ARC function.
