HDMI is the gold standard for delivering the highest-quality audio and video signals over a single cable, from an AV source to your display or projector. The flat, tangle-resistant design of the Manhattan Flat High Speed HDMI Cable with Ethernet is ideal for installations in walls, under carpets or along baseboards. The cable's unique design also makes it easy to roll up or out without worrying about snags and tangles. Gold-plated contacts and double shielding (aluminum foil and Mylar braid) provide maximum signal integrity for a resolution up to 4K60 in Dolby Vision™ and Dolby Atmos® with zero EMI interference. Expanded features include an Audio Return Channel to allow your TV's audio to transmit through your audio system without a separate cable.
