Ultra High Speed HDMI® Cable Certification Program

The HDMI 2.1a Specification includes a new cable - the Ultra High Speed HDMI® Cable. It’s the only cable that complies with stringent specifications designed to ensure support for all HDMI 2.1a features including uncompressed 8k@60 and 4K@120. The cable’s increased bandwidth capability supports up to 48Gbps.

The Ultra High Speed HDMI Certification Program is a mandatory certification program for all Ultra High Speed HDMI Cables; and ensures quality Ultra High Speed HDMI Cables reach the market and support 4K and 8K video, HDR, VRR, eARC, and all other HDMI 2.1a features. Cables are also required to be tested and certified to ensure low EMI to reduce the possibility of interference with wireless networks, streaming media players, Bluetooth devices and mobile phones.

All certified cables of any length must pass certification testing at an HDMI Forum Authorized Testing Center (Forum ATC). Once certified, cables will be required to affix an Ultra High Speed HDMI Certification Label to each package or unit of sale enabling consumers to verify the certification status of the product.
