HDMI Cables and Audio Transmission
HDMI (High-Definition Multimedia Interface) is a widely used audio and video connection standard.

HDMI cables come in various specifications, each designed to support different levels of data transfer, resolution, and audio formats.
Dolby Atmos and HDMI Cables
There’s a common misconception that you need special or expensive HDMI cables to enjoy Dolby Atmos. Let’s clarify the facts:

- HDMI Versions: HDMI cables are classified by version numbers, such as HDMI 1.4, HDMI 2.0, HDMI 2.1, etc. The HDMI version determines the maximum data transfer rate and supported resolutions. While Dolby Atmos can be transmitted through HDMI 1.4 and later versions, it’s essential to have an HDMI version that supports the desired video quality as well.

When selecting an HDMI cable for Dolby Atmos, consider the following:
- HDMI Version: Ensure your HDMI cable and equipment support the HDMI version required for your video and audio quality needs.
