Special HDMI Cable Certification Programs 
All HDMI cables must be tested for compliance with the specification and in addition there are two special certification programs administered by HDMI LA for added compliance assurance with anti-counterfeiting labeling.
The Premium HDMI® Cable Certification Program was launched in 2015 for High Speed HDMI Cables and adds testing and certification to ensure support for 4K@60Hz and 18Gbps bandwidth. All lengths of cables must be tested at HDMI ATCs and pass EMI testing. With more 4K content being distributed, this cable is vital to both the consumer and commercial sectors especially cable, satellite and IPTV set-top box installations. It also requires packaging to display the Premium HDMI Cable Certification Label for added verification of compliance and to prevent counterfeiting. More info: https://hdmi.org/spec/premiumcable
The new Ultra High Speed HDMI® Cable Certification Program is soon launching and supports the new Ultra High Speed HDMI Cables from the HDMI 2.1 specification. It’s the only cable that complies with stringent specifications designed to ensure support for all HDMI 2.1 features including uncompressed 8k@60 and 4K@120 and the increased bandwidth of 48Gbps. The program is mandatory for all Ultra High Speed HDMI Cables; and ensures quality cables reach the market and support 4K and 8K video, HDR, VRR, eARC, and all other HDMI 2.1 features. All certified cables of any length must pass certification testing at an HDMI Forum ATC and be tested to meet current EMI requirements to minimize wireless interference. Cables will be required to affix an Ultra High Speed HDMI Certification Label to each package. More info: https://hdmi.org/spec21Sub/UltraHighSpeedCable
Both certification programs utilize HDMI LA's proprietary HDMI Cable Certification scanning app available to end-users to verify certification and check the reseller brand and cable length. Also, both programs include HDMI LA audits of marketplace cables to ensure that production cables continue to pass certification testing during their product lifetime.
