I discovered most of my HDMI 2.1 cables aren't certified, and it's shockingly common
A recent investigation revealed that many HDMI 2.1 cables are not certified, despite being marketed as such. The ambiguity in labeling standards allows cables to be sold under the HDMI 2.1 name without meeting the necessary specifications. This has led to widespread confusion among consumers regarding the actual capabilities of their HDMI cables.
- ▪Most cables marketed as HDMI 2.1 do not deliver on the promised specifications.
- ▪The HDMI labeling standard is ambiguous, leading to confusion about cable capabilities.
- ▪Only Ultra High Speed cables are guaranteed to support the full 48Gbps required by HDMI 2.1.
