HDMI (ARC) Connection

"
Some models may not support ARC.
Before connecting any external devices and cables to the TV, first verify the model number of the TV
you purchased. A sticker showing the model number is attached to the back of the TV. The connection
method varies depending on the model.
ARC (Audio Return Channel) enables digital sound output using just an HDMI cable. However, ARC is
only available through the HDMI (ARC) port and only when the TV is connected to an ARC-enabled AV
receiver.

The number of connectors and their names and locations may vary depending on the model.
Connect an HDMI cable to the TV's HDMI (ARC) connector and the device's HDMI output connector.
