Quick answer
Look for the certification label on the box, scan it, and match what it shows. HDMI.org says certified Ultra High Speed and Ultra96 cables must carry a certification label on every package, the scan works with standard QR code apps, and it shows the brand name, model number and length. The cable name also has to be printed on the cable jacket.

- Find the label. Ultra High Speed and Ultra96 cables must have the certification label on each package or unit of sale, HDMI.org says. Premium High Speed cables have their own Premium certification label.
- Scan it. HDMI.org says the labels can be scanned by standard QR code apps. Its label transition notice says newer labels use a QR code in place of the older data matrix code.
- Match it. The scan shows brand, model number and length. Check those against the cable in your hand, and check the jacket for the cable name.
Why it matters
HDMI.org warns that sellers may use marketing terms instead of official cable names, and that some cables are counterfeits. It says Ultra High Speed cables must pass testing at an HDMI Forum Authorized Testing Center, are tested for low EMI to reduce interference with Wi-Fi and Bluetooth devices, and are bought from stores and marketplaces for ongoing audits.
Shopping online
HDMI.org's optional Verification Banners on maker and reseller sites can be clicked or scanned to show the same brand, model and length as the physical label.
