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.
At this point we should just swing to 10 gbps sfp+ ports, it's faster, it's lower latency, it's upgradable to 100gbps, it travels over fiber, but most importantly, it is a network protocol and we can use it for our Internet.
sfp+ can do audio and video? I've only ever used it for networking
1s and 0s, you can do anything with em
But what about -1s? 0.5s?
They tend not to fit down the cable, but they're working on it for the next revision.
Wouldn't want to block the tubes, good to know.
Also 0s and 1s!
