hdmi arc vs hdmi dvi

HDMI ARC (Audio Return Channel) is a feature that allows audio to be sent from a TV back to an AV receiver or soundbar through the HDMI cable. It simplifies the connections and eliminates the need for a separate audio cable. HDMI DVI (Digital Visual Interface) is a connection standard that allows for video signals to be transmitted from a source device to a display. However, unlike HDMI, DVI does not carry audio signals, meaning a separate audio connection is required to transmit sound. In summary, HDMI ARC enables two-way audio transmission through an HDMI cable, while HDMI DVI is a video-only connection that requires a separate audio cable for transmitting sound.
