The right HDMI cable for Dolby Atmos helps connect your TV, soundbar or AV receiver for immersive audio with a sense of height and movement. However, Dolby Atmos compatibility depends on your entire home theater setup—not just the cable. Your content, playback device and audio system must support the Atmos format being used, and your TV must support compatible audio passthrough if it sits between the source and your speakers. HDMI ARC, or Audio Return Channel, can carry Dolby Atmos delivered through Dolby Digital Plus on compatible equipment, a format commonly used by streaming services. HDMI eARC, or Enhanced Audio Return Channel, supports higher-bandwidth audio formats, including Dolby TrueHD with Atmos found on many 4K Ultra HD Blu-ray discs. For a TV-to-soundbar or TV-to-receiver eARC connection, choose a High Speed HDMI Cable with Ethernet or a certified Ultra High Speed HDMI Cable, and connect it to the HDMI ports labeled eARC on both devices. Check your equipment’s specifications to confirm format support, since an HDMI cable alone cannot add Dolby Atmos or eARC capabilities. Choosing the best HDMI cable for your Dolby Atmos home theater also means considering the video signal it needs to carry. A certified Premium High Speed HDMI Cable supports bandwidth up to 18 Gbps and is suitable for many 4K at 60Hz HDR setups, while a certified Ultra High Speed HDMI Cable supports up to 48 Gbps for demanding video formats such as 4K at 120Hz and 8K at 60Hz on compatible equipment. That extra bandwidth is useful for advanced gaming and video features, but it does not inherently improve Dolby Atmos sound quality. Choose a cable length that reaches comfortably without putting strain on the connectors; for longer runs, consider an active optical HDMI cable and verify that it supports eARC if you plan to use it for TV audio return. To complete your Dolby Atmos setup, enable ARC or eARC as appropriate and select the audio passthrough or bitstream settings recommended by your device manufacturers. A compatible, reliably connected HDMI cable helps your soundbar or AV receiver receive the intended audio signal, so you can enjoy overhead effects, clear dialogue and enveloping sound from supported movies, shows and games.

FAQ

HDMI cables carry digital audio and video between devices. Dolby Atmos is an audio format that includes information for placing sounds in a three-dimensional sound field. The cable transports the signal, while compatible equipment processes the Dolby Atmos audio.

HDMI cables are certified by HDMI cable category, not by Dolby Atmos compatibility. Labels such as High Speed HDMI, Premium High Speed HDMI and Ultra High Speed HDMI identify cable categories. Dolby Atmos support also depends on the content, connected devices and audio connection type.

HDMI ARC and eARC send audio from a TV to a soundbar or AV receiver through an HDMI connection. ARC can carry Dolby Atmos encoded in Dolby Digital Plus when the connected devices support it. eARC also accommodates higher-bandwidth formats, including Dolby Atmos carried in Dolby TrueHD. For an eARC connection, HDMI guidance specifies a High Speed HDMI Cable with Ethernet or an Ultra High Speed HDMI Cable.

For an Audio Return Channel connection, connect the TV's HDMI port labeled ARC or eARC to the soundbar's corresponding HDMI ARC or eARC port, often labeled HDMI OUT. A separate media player or game console may connect to the TV or to an HDMI input on the soundbar, depending on the available connections and supported audio formats.

HDMI supports the audio formats used to transport Dolby Atmos, including Dolby Digital Plus and Dolby TrueHD, depending on the connection and equipment. Optical audio connections do not carry these Dolby Atmos formats. Optical carries audio only, while HDMI can carry both audio and video.
