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.

Will this solve eARC sync issues on existing devices that support 2.1? Like I could just get a new cable and it would work?

Let me know when we have cables that can hit 1000Hz at 8K, so I can finally own a blur-free OLED. Until then, I'm perfectly content with 4K120.

Perfectly content with 4K120

Come on. You say it like it's a compromise.

[–] Psythik@lemmy.world 6 points 2 days ago (1 children)

The point I'm making is that we will still have to deal with motion blur at 240 and 480Hz, so I might as well save some money and hang onto my 4K120 OLED until we reach 1000Hz.

Seems like you got a perfect is the enemy of good kinda situation going on.

I'm picturing cables in my head like the ones they deploy on seabeds to accommodate this 😄

[–] Kbobabob@lemmy.world 6 points 1 day ago (1 children)

Which is just silly. Displayport is 80 Gbps already.

[–] InFerNo@lemmy.ml 1 points 1 day ago

Was there any doubt this was serious?

[–] BlackLaZoR@fedia.io 1 points 2 days ago

For TVs there's little to nowhere to go beyond 4k 120hz. Same for monitors - I have 4k 144hz display over displayport 1.4a and pushing resolution and refresh rate further has no purpose anymore.
