The cable category associated with HDMI 2.1’s 48 Gbps bandwidth is Ultra High Speed HDMI Cable. Cables that support HDMI 2.1 features do exist; the misleading part is treating “HDMI 2.1” as the official cable name or as proof of certification.
What “HDMI 2.1 cable” actually means
HDMI 2.1 is a version of the HDMI specification, announced by the HDMI Forum on November 28, 2017. The Forum named the cable category supporting 48 Gbps bandwidth for uncompressed HDMI 2.1 feature support Ultra High Speed HDMI Cable. In its announcement, the Forum said: “The Ultra High Speed HDMI Cable supports the 48G bandwidth for uncompressed HDMI 2.1 feature support.” HDMI Forum announcement.
So a retailer’s phrase “HDMI 2.1 cable” may be informal shorthand for a cable intended for newer HDMI capabilities, but the phrase alone does not establish that the cable is certified. For shopping, look for a certified Ultra High Speed HDMI Cable and verify its label.
Do you need one for 4K at 120 Hz?
Only if the complete setup needs the cable capability. The HDMI Forum lists 4K at 120 Hz and 8K at 60 Hz as examples supported by the HDMI 2.1 specification; those examples do not guarantee that every source, display, cable, or configuration supports them. Check the capabilities of both devices and the signal features you intend to use. If your current cable reliably carries the signal your setup needs, the official guidance does not establish that you must replace it.

For a setup requiring the bandwidth associated with HDMI 2.1 features, a certified Ultra High Speed cable is the relevant category. The label identifies the cable category; it does not override limitations in the source, display, settings, or connection.
How to verify an Ultra High Speed cable
- Check the packaging or unit of sale. HDMI Licensing Administrator says compliant Ultra High Speed HDMI Cables must carry the official Ultra High Speed HDMI Certification Label. HDMI cable guidance.
- Scan the label’s QR code. Use a standard QR-code app to check the certification record, as HDMI Licensing Administrator advises. A seller’s wording by itself is not the same as this verification.
- Check the cable jacket. The official cable name is also required on the cable jacket. HDMI cable guidance.
Compare the cable to your actual connection
- Category and certification: Choose the certified cable category appropriate to the required bandwidth, rather than relying on the phrase “HDMI 2.1.”
- Bandwidth need: Ultra High Speed is the 48 Gbps category associated with HDMI 2.1. HDMI 2.2 introduces the Ultra96 designation for cable bandwidths of 64, 80, or 96 Gbps. HDMI 2.2 overview.
- Length and construction: Account for the run you need and the cable’s construction. HDMI’s overview says usable cable length depends on cable type and construction; it does not set one maximum length for every cable. HDMI cable guidance.
- Connectors: Confirm the connector type fits both devices.
Where HDMI 2.2 fits
Ultra96 is the newer HDMI 2.2 cable designation for 64, 80, or 96 Gbps bandwidth levels. HDMI’s overview says Ultra HDMI cables are backwards compatible with existing HDMI devices, while Ultra High Speed remains the 48 Gbps cable category. This newer terminology does not change what to look for when a setup specifically calls for the HDMI 2.1-associated 48 Gbps category: certified Ultra High Speed HDMI Cable.
