Ultra High Speed HDMI® Cable Certification Program
The HDMI 2.1b 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 2.1b 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 2.1b 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.
To identify the cable, make sure the packaging displays the required Ultra High Speed HDMI Certification Label shown above. Please note the label includes the official Cable Name Logo printed on it. The name is also required to appear on the outer cable jacket itself. To verify the cable has been tested and certified in compliance with the HDMI 2.1b Specification, the label can be scanned by the HDMI Cable Certification app available on the Apple App Store, Google Play Store and other Android app stores.
New HDMI Cable Certification Labels
The HDMI Cable Certification Program supporting Ultra High Speed HDMI Cables is changing to a new generation (Gen 2) label. The original Gen 1 labels in the market will continue to be supported with the proprietary scanning app for the immediate future. Please note that consumers will be seeing two versions of the labels and they use different scanning apps. Please download the informational brochure for complete details here 
Shopping for the HDMI Cables Just Got Easier
Shopping for HDMI® Cables can be confusing. Resellers may use a variety of marketing terms and may not use the official HDMI Cable name designations, and many websites may recommend cables only based on receiving affiliate payments. And worst of all – some cables are counterfeits.
The Verification Banners are an optional add-on to the existing HDMI Cable Certification Program. The website banners enable consumers to verify the certification status of cables while shopping on manufacturer and reseller websites. The Verification Banners can be either clicked or scanned, displaying the brand name, model number and length - the same as when scanning the physical Certification Labels affixed to the cable packaging.

Continuous Auditing Ensures Continuous Compliance and Performance
In order to ensure a UHS Cable stays in compliance to the specification over its product life, we purchase cables in stores and online marketplaces and send them in for testing to Forum ATCs. If a cable fails, the adopter has a chance to correct manufacturing issues or else no further certification labels can be ordered for that cable. However, if a cable passes, the adopter receives a letter confirming it is has passed the compliance audit and the label’s scan result also confirms the audit pass. This enables resellers and consumers to confirm continuous compliance.
