Better than expected, HDMI2.2 is announced with 96Gbps bandwidth and new cable certification

HDMI2.2 supports up to 4k 320hz at 10bit RGB 4:4:4 with HDR. It can also
extend to 4k 480hz with DSC enabled.

HDMI 2.2 also contains support for a new audio sync protocol that aims to eliminate audio syncing issues for home theatre systems

 

[Blackbadger]

Yeay, now all I need are new supported screens, new gpus, new Amp , 5 new hdmi cables & a supported KVM. Cant see much change from 10k

All joking aside, Its great that the cables standards are finally catching up with what's needed, however it will likely be years for it to filter through to devices to enable a compatible setup.

I see a new display port standard has also been announced today DP 2.1b - however it max's out at 80Gbps active 3m max length. Which is less than the new hdmi standard, which is supprising, I'd have hoped a new display port to be able to really push things and allow high fps, high res, and high pallet. Maybe next decade....

Good to see the sync issues are being improved. Definitely a quality of life improvement that’s needed. Depending on source, I have various different audio delays to program into my amp.

Someone smarter may know this - with cables at 96gbps, why are we using copper instead of something like a new fibre optic standard? Surely things like attenuation and the issues with so many HDMI cables I’ve had (that can’t carry the signal intended, sometimes over time) would be avoided. Perhaps new issues introduced but it feels like we must be getting near some limit of practicality on copper. A certification is certainly one thing that is important but it’s tricky to even know which brands to trust.

I also find the implementations of ARC and CEC often lacking and flaky. Is it just me?

Was playing around with a bandwidth calculator and looks like 1000hz is possible now, if someone comes up with a 1000hz 1080p esports monitor, it can be driven with HDMI 2.2 without compression and full RGB 4:4:4 color

Unfortunately it doesn't look like any major devices will use HDMI 2.2 this year, all TVs announced so far at CES are HDMI 2.1, we have no HDMI 2.2 monitors yet either and its likely the newest GPU's will still be HDMI 2.1 as well. While not yet announced, I'm fairly confident new soundbars and audio products at CES will be HDMI 2.1 as well unless they are only launched much later this year.

We'll have to wait for 2026 to take advantage of this new tech

For me, that means I'll be avoiding buying new AV tech this year where I can so I can wait for next year

I've had issues with ARC on HDMI 1.4, but since changing to a HDMI 2.1 TV and soundbar, I've had zero e-ARC issues since and its been years for me now with no issues - no disconnects, no handshake errors, no audio sync issues etc, zero problems for me personally.

As for copper cables, the higher the bandwidth, the shorter, or thicker the cable needs to get. I've got a 10 meter HDMI 2.1 cable and its copper and it works flawlessly and its super thick
I believe HDMI 2.2 cables will either be very short, or if they are not short they'll be incredibly thick or if its thin then its fibre optic

Have you seen the coat of the fibre hdmi cables? Can imagine many people paying 100 quid for a cable, it's like being back with monster scary leads . I think hdmi is only 5 m max anyway and after that it's fibre, likely for those reasons.

I suppose they are not common so a bit niche and therefore expensive. But they are cables that encode/re-encode the signal to and from HDMI so that fibre can be used. I was thinking more like a fibre connectivity standard that means future TVs and hardware would have that built in, so the cabling was only a simple fibre connection, which would be cheaper. Maybe it makes devices more costly though. I have some TOSLINK cables that are basically that I believe, but that is a very old standard. But maybe you can see what I mean.

I'm not actually sure what the difference is between the internals of toslink Vs hdmi fibre, I assume much lower wavelength (thus bad for eyes) to get the throughout.

In a way I'm kinda glad to see these HDMI 2.2 certified cables coming.

I've found it can be a nightmare to get good working HDMI 2.1 cables, even certified, a lot of them can be very hit and miss. 4K60 seems to be relatively achievable now, but I recently had to replace a certified 2.1 cable after upgrading to a new 4k120 capable AV Receiver setup, and it took 3 attempts to get one that worked properly and somewhat reliably at 4K120 with HDR etc. Unfortunately getting a decent cable tester is quite expensive, and the ones built into at least Denon AVRs seem somewhat inconsistent, but at least a cable that cannot do the higher bandwidth always fail, whereas good cables will only fail some of the time, so as long as I rerun the test 4-5 times, it'll usually come up on at least a few of them as passing the higher bandwidth tests lol

These were all HDMI 2.1 certified cables too!

With the HDMI 2.2 specs being more demanding, it should get easier to get cables capable of doing this, even if they cost a bit more, as 96Gbps tested cables shouldn't struggle to pass 48Gbps.

Good thing there's loads of GPUs that can run 4k at 480fps . I know it's a chicken and egg, so might see the connection make it's way to high end stuff.

 

[Grim5]

Apparently all cables will need to be 96GB/s to claim they are hdmi 2.2 and all cable models will have to be inspected for 96GB/s, but there is a big problem- this only applies to cables, not the ports!

Your TV will be able to claim it's hdmi2.2 even if its ports only support 60GB/s or only supports some features - so prepare for a massive minefield of electronic products in 2026

 

[Alexrose1uk]

Honestly, as HDMI 2.1 cables have been so hit and miss, even the certified ones, this is still a step in the right direction.
I do believe it should be mandated TVs actually advise in thier specification what bandwidth they support, but, babysteps, given the requirements all round are far more stringent on 2.2 than 2.1. Probably due to all the issues 2.1 caused.

 

[peahead]

Are we going to get Tv's with 1 HDMI port that only supports HDMI 2.2 like before .

Ive had no trouble with Anker HDMI 2.1 cables - bought a whole load for various sources after I upgraded my receiver and no problems 4k120

That depends on the SoC available. LG has always had four hdmi 2.1 ports, its Sony and other small brands that don't have their own SoC that buy crappy off shelf ones

No doubt it will be LG and Samsung providing the full beans again on all ports while the likes Sony and Panasonic likely providing only one.

Ive had no trouble with Anker HDMI 2.1 cables - bought a whole load for various sources after I upgraded my receiver and no problems 4k120

Glad to hear, I didn't try Anker ones, but had bought a load of others, and lets just say hit and miss!! When I was trying to sort my issues earlier, I bought at least 3 cables, and already had multiple that were meant to be capable, but hit and miss to the extreme.

That, hopefully, means Anker are regularly/thoroughly testing batches before passing to inventory, but based on my experience many others are not as reliable; or maybe I got unlucky; but I tried a number of brands, KabelDirect, Zeskit Maya, Sniokco and others, and even though some of these came very highly rated and reviewed, and were all supposedly HDMI2.1 certified (and they werent excessively long either, 2M IIRC), they did not all pass reliably, or encountered issues when running 4k120 with HDR (4K120 without HDR was more reliable, and 4K60 was generally fine, but as you pushed up the bandwidth requirements, the number of cables that just worked every time dwindled). As I remember the 2nd KabelDirect one was the one that ended up staying in the setup; but the whole thing sent me for a good run around for a week or two of replacements/reordering etc.

I do wish the Denon AVR HDMI tester was more reliable, as that fails intermittently on known good cables; but I had multiple issues with faulty cables that just did not work as promised and caused issues (and would fail the tester consistently no matter how many times I ran it, cables that are good would at least pass if you re-ran the test multiple times, and would pass at least sometimes).

If I need to buy more, I'll add Anker to the list of ones that are probably good.

Either way, this is why I'm happy that the HDMI 2.2 cable certification and testing standards sound to be more stringent and demanding. Hopefully means less faulty/inadequate inventory reaching consumers; and cables are always a headache if they're not right, as then you've got to work out whether the issue is configuration, equipment or the cable, and that's always a pain.

Agree its good theyre going to put better checks in place. I have to admit I read a lot of bad stuff about the reliability of HDMI 2.1 cables but Ive had a number of Anker devices over the years and never had any reliability issues so I stuck with them...

Also as an entire aside am I right thinking youre a BMS Alumnus?

 

[Alexrose1uk]

Yeah, less stress for all involved, and I can personally vouch for those reported reliability issues! Which is so bloody stupid as cables are so integral for everything to work; and they're such a necessary part of modern tech, that you'd think in 2025, they'd basically be bulletproof, but no.

And BMS - not quite. I actually did meet another person with the surname Rose (think his first name might have been Alan...funny the things you remember) who went there IIRC many years ago, and actually ALMOST DID go there on a bursary/scholarship (went through the testing, for site tours etc, passed those entry exams etc by my understanding, but it never quite came together for a couple of reasons.) Honestly funny you mention it, as it was so long ago now I'd not thought about it for quite some time. My life would probably have been very different if I had! Guessing you may have known the other guy?

I ended up in schooling/sixth form in Leighton Buzzard and MK for my sins lol
There is also another guy with the exact same first/last name as me, who works in the same industry as I do, who now works for BT, but I was in the industry a few years prior so am technically his senior - that's also caused a bit of confusion over the years, especially as its not such a common name combo - funny world
