What Is the HDMI Out Port Used for on Receivers?
HDMI out ports provide a connection method between your receiver and an HDMI enabled monitor or other device. You can use HDMI cables to transmit audio and video signals from the receiver to your TV, computer or speaker system.
The HDMI interface allows you to transmit both audio and video signals over a single cable. With HDMI cables you can greatly reduce the number of cables and wiring for your home theater equipment.
Connect an HDMI cable from your set-top box to the "HDMI IN" port on your receiver. Insert an HDMI cable into the "HDMI OUT" port on the receiver and connect the other end to the "HDMI" port on your TV. Select the "HDMI" input on the TV to display the picture from the receiver.
HDMI is the only industry supported all-digital interface. The interface supports high definition, enhanced and standard signals.
