The HDMI Forum is using CES — the annual showcase of all things home theater — to announce the new HDMI 2.2 specification. In a press release this morning, the trade association confirmed that the new spec will up total bandwidth significantly to a new high of 96Gbps. And yes, that means the introduction of an “Ultra96” HDMI cable that “enables all the HDMI 2.2 specification features.”

“Higher resolutions and refresh rates will be supported and more high-quality options will be provided,” the HDMI Forum said in its release. An example of an HDMI 2.2 cable (below) calls out some of those, including 4K at up to 480Hz, 8K at up to 240Hz, and 10K at 120Hz. Current HDMI cables can already pass 4K at 120Hz, so I doubt most people will feel any temptation to upgrade for years to come. And you’ll need content for any of these higher resolutions to be worthwhile, and there’s still a dearth of native 8K entertainment out there. 

But with many TVs now offering 4K at up to 144Hz, and as consumers gravitate towards larger screens, the HDMI Forum sees ample reason to keep pushing forward. 

There is at least a more helpful aspect of this spec for everyone: HDMI 2.2 includes a “Latency Indication Protocol (LIP) for improving audio and video synchronization, especially for multiple-hop system configurations such as those with an audio video receiver or soundbar.” In my experience, HDMI 2.1 and eARC have mostly resolved frustrating audio / video sync issues, but they can still pop up as a frustration depending on your setup. Apparently HDMI 2.2 will go further in keeping everything lined up and keeping this headache in the past.

Interestingly, the HDMI Forum is already anticipating tariff issues and has implemented an extensive certification program that includes anti-counterfeit labeling on packaging. You certainly can’t miss the Ultra96 badging.

HDMI 2.2 will be released in the first half of this year and be widely available “to all HDMI 2.x adopters.” Your TV and external devices will need to support the specification in order to unlock that new level of bandwidth, so we’re just starting down what’s inevitably going to be a long road.

This is a mixing issue. Interesting video on it here.

This isn't really a cable issue though. The inaudible dialogue is due to bad masterinf of the sounds for home systems (i.e.: the slunds were originally mastered for 5.1, 7.1,or for fucking cinemas with 128 channels)

Or it is just the choice of the director, because he likes it that way (Cough Christopher Nolan Cough)

What are these cables for when all new displays that support it will have builtin app that everyone is going to use to watch streaming services with. The last time I have seen an external streamer used was for someone with an older TV where the builtin apps are no longer updated.

I get the need for eARC usage, but that's already implemented... So...?
