There is no functional difference between the B9 and the C9. The processor is supposedly less powerful, but it does the same things with the same outcome, except for very specific never-used formats reserved for the Alpha 9.
No one AFAIS has positively tested it yet, since there are no HDMI 2.1 sources, but LG's explicit advertisement of support of 4K120 and specifically 48 Gbps on major online outlets indicates it is a full-spec chip.
Please show me this. None of this information is anywhere as best I can see.

That is the C9 and E9 owner's thread so telling him to ask in the "owner's thread" is still not correct. He did ask there earlier BTW.
The C9 and B9 have different processors so using what the C9 can do to say what the B9 can do is not definitive. That being said, since the HDMI 2.1 is handled by a different chip so as long as the A7 Gen 2 can handle the speed we should be good.
Where did they advertise 4K120 and 48Gbps for the B9? Not seeing it at the usual online stores.

Unfortunately that link doesn't make it quite clear either. It makes it clear that the C9,E9 and W9 will support HDMI 2.1, but all it says about the B9 is

"Some features will be added through a firmware update after launch". I wonder what those will be? Hopefully LG's updates are more carefully engineered, and timely, than the panel updates for the C8 line was/is. I never had any issues with my C8 but there were lots of folks who did with the flurry of updates since last October.

How can you confirm fully compliant HDMI 2.1 when there aren't any consumer devices yet (STB's, UHD/BD players, etc) let alone content, to test it on? Just because the mfr says so doesn't mean it's going to actually work well in the wild.

Do they say fully compliant or just compliant. Splitting hairs I know but I don't totally trust any mfr (product or cable) given how carefully worded their claims can be. It would be nice if they listed which HDMI 2.1 options it is compliant with instead of just having the consumer assume that compliant covers all of the options out of the box.

There is no "fully compliant" or "just compliant" designation. Only a list of features and resolutions supported.
From https://www.hdmi.org/manufacturer/hdmi_2_1/index.aspx:
Q: What are the HDMI 2.1 marketing feature names and their acronyms if any?
A:
- Ultra High Speed HDMI Cable
- Auto Low Latency Mode (ALLM)
- Enhanced Audio Return Channel (eARC)
- Quick Frame Transport (QFT)
- Quick Media Switching (QMS)
- Variable Refresh Rate (VRR)
- 4K100A
- 4K100AB
- 4K100B
- 4K120A
- 4K120AB
- 4K120B
- 8K50A
- 8K50AB
- 8K50B
- 8K60A
- 8K60AB
- 8K60B
Q: Can I use “HDMI 2.1” in my marketing
A: You can only use version numbers when clearly associating the version number with a feature or function as defined in that version of the HDMI Specification. You cannot use version numbers by themselves to define your product or component capabilities or the functionality of the HDMI interface. And please note that NO use of version numbers is allowed in the labeling, packaging, or promotion of any cable product.

We've had this discussion before
. If the mfr indicates HDMI 2.1 compliant in their marketing, does that automatically means all of the above options are being met with no further explanations needed? I certainly hope you are correct. Unfortunately HDMI.org has no enforcement capabilities so it's basically an honor system. If they said their product is compliant with HDMI 2.1 VRR, eARC, ALLM, etc that would be fine, and comply with the HDMI marketing rules, but I haven't seen that yet.

Yet it's not sinking in.We've had this discussion before
They are not allowed to. If a manufacturer does ignore the rules, and I suspect the cheap brands will, and say "HDMI 2.1 Compliant" or some other terminology then it can mean anything. One thing for sure is that if you see that kind of rule breaking terminology then don't by the TV. They'll most likely not have done any compliance testing either.
I prefer the term implements to compliant. They're not complying to a set of rules, they're implementing individual features based on a technical specification. Compliant makes it sound like they have to meet a certain level of feature support which is not true.
I have not seen any mention of HDMI 2.1 on LG's website for the tech specs of any of their *9 TVs. Have you seen them breaking the HDMI.org marketing terminology rules somewhere?
The worst offenders currently are the myriad of cable manufacturers touting HDMI 2.1 cables. The reputable brands like Belkin and Monoprice do not have HDMI 2.1 anywhere on their 48Gbps HDMI cable pages.

I agree that the term compliant should not be used in describing HDMI 2.1 options so if it will make you feel better, then I'll use implement when discussing HDMI 2.1. I just hope that the marketeers follow suit.Yet it's not sinking in.

LG does follow the HDMI marketing rules by specifying "eARC (HDMI 2.1)" in their specification listings for the new C9, which is fine, and what I have been staying all along. I never said that LG broke any marketing rules. In fact they are doing what I hope everyone will do, cable and device mfrs alike.
Belkin has since moderated their cable description for their Ultra HD High Speed HDMI cable, which stated that it "supports VRR as specified in HDMI 2.1", with speeds "up to 48Gbps", to stating that it is now certified by an ATC (Premium) for HDMI 2.0 specifications up to 18Gbps. Their 48Gbps cable is no longer available directly from Belkin, at least not that I can find on their website. Belkin took a lot of heat when they first introduced that cable so that's probably why it is no longer available from them, yet.
I think we are saying the same thing only coming at it from different angles.

Heh. It’s not about me wanting to feel better. I just suggest less ambiguous terminology sometimes and hope people will agree that it’s a better way of describing things.
I was on the Belkin page earlier that has your quoted text: https://www.belkin.com/us/p/P-AV10176/
Other that eARC and 48Gbps (and the resolutions this allows), none of the other features require anything special about the cable. So while not wrong that it allows VRR, so does all other HDMI cables. But that’s the marketing department pushing the envelope.
HDMI 2.1 chipsets aren't officially released by the HDMI consortium as of now, an Onkyo AVR that got launched in the second half of 2019 does not have it. I asked the reason on the Onkyo support forums and they told me the chips aren't available to third party vendors yet so their avr's still don't have HDMI 2.1. I asked there what about LG 2019 oleds, I was told LG is using a in house manufactured hybrid HDMI chipset that does both HDMI 2.0 and HDMI 2.1, that is how tlhey got ahead of everyone, AVR manufacturers don't do their manufacturing of HDMI chipsets, they procure them through the channels provided by the hdmi consortium and the chipsets aren't available yet. He told me AVR models in 2021 might start having them. And future HDMI 2.1 devices won't employ the hybrid HDMI solution that LG is using,they will have a single 48gbps chipset.
Whether LG oleds support HDMI 2.1 all features is guesswork because full compatibility cannot be tested as HDMI 2.1 devices aren't available . For sure these LG oleds don't support any 8k and 10k resolution modes of HDMI 2.1 because these are 4K tv's. If features like 4K 120hz 4:4:4, 10/12 bit work or not cannot be properly tested yet.
