specifications?

• are they 'High Speed Cables' (18/gps) - that the manufacturer 'confirms' the '24/gps'?
• at this point in time :: do you sell any Ultra High Speed (Premium Certified?) cables?
• just curious

questions

• what is the 'required' bandwidth for eARC? (do you know?)
• what is the 'required' bandwidth for HFR? (do you know?)
• what is the 'required' bandwidth for 8K/60? (do you know?)
• hopefully, you know for 'each (feature) individually'

how about 'Premium Certified Ultra High Speed Cable'?

The HDMI cable thing, to make everything working ... audio/video 4K/8K players TVs projectors receivers surround sound processors streamers servers Internet etc.

eARC requires nothing more than 18 gbps cable
HFR if it is 4K/120 8-bit 4:2:0 requires 22 Gbps cable
8K/60 8-bit 4:2:0 requires no more than 22 gbps cable

Premium Ultra Certified only means the cable is above 18 gbps. It can mean 20, it can mean 22, or it can also mean 48.

[jibucha]

that's simply 'incorrect' (and - 'extremely so - at that)

• you're 'furthering confusion' regarding HDMI
• you can contact HDMI Licensing 'directly' to 'confirm' (both arbitrary and confusing - as 'i perceive it')
• if you were correct; that would not benefit 'anyone' (as - 'your idea' of a 'guideline')
• 'accurate/reliable' information is important/required (no assumptions/guessing - are permitted)
• Premium Certified Ultra High Speed Cables :: to qualify, 'it's a must' that the cable 'achieve/maintain 48/gps to lengths of 3M (approximately 9/ft) -
  Premium Certified Ultra High Speed Cables :: once certified, each has a 'special logo/gold sticker' that's the 'reliable guide to us consumers, that the cable is 'confirmed to achieve the 48/gps' as required for 'all' Premium Certified Ultra High Speed Cables' (passive to 3M)
  finally implementing specifications/testing (mandatory) to benefit the consumer/industry (a long time coming - should have been 'from the beginning')
• HDMI Licensing ::
• sorry

[jibucha]

not what 'i asked' (my questions)

• 'if i was not clear' - which i thought that i was
• what is the 'specific bandwidth requirement' for 'each specified feature' (individually)
• you prevously indicated 'your ideas of - cable speed' which unfortunately are incorrect (for several reasons - highly misleading)
• those seeking clarification/information 'do not need' speculation
• rather - accurate/detailed/reliable information
• so - do you know the answers to my previously posted questions or not? (if not, why not either not post or post 'saying so' - no harm in that?)
• so - "nothing more" is 'simply' meaningless (your 'cable' references as posted are inaccurate/incorrect with regards to HDMI (cables) as 'currently mandated' by HDMI Licensing
• please :: if you're going to be helpful, do your research (some of us do)

Really? I was teaching HDMI just several weeks ago. All my information is from HDMI LLC.

There is not a single equipment that can measure 48 Gbps for certification.

Before criticizing, check ACTUAL REAL LIFE information and not only reading a website.

[jibucha]

not so

• just because your 'teaching' does not mean that 'what youre teaching is accurate/correct'
• i am not 'teaching' and 'my information' is correct and 'verifiable' by HDMI Licensing (LLC)
• 'reading a website' (not so) :: my information is 'directly from HDMI Licensing' (LLC)
• be careful (i am not misinformed/wrong)
• ACTUAL REAL LIFE information (i agree, but 'highly unrealiable')
• "All my information is from HDMI LLC." (that's simply not possible/true - inconsistent with 'their information')
• "There is not a single equipment that can measure 48 Gbps for certification" (while i doubt this information, and i will further research, then there simply cannot be - currently - any Premium Certified Ultra High Speed Cables available)
• seems odd though, that the current LG OLED displays (2019) utilities chipsets/hardware, that 'measure' 48/gps, yet 'cables' related measurements are absent

There seems to be confusion depending on what you are referring to (and I could be misunderstanding this as well, so, apologies if I also am incorrect).

From HDMI.org

https://www.hdmi.org/manufacturer/pr...n_Program.aspx

Premium HDMI Cable Certification Program
"Cables are tested to ensure they support the full 18Gbps bandwidth from the HDMI 2.0b specification plus an EMI test to ensure cables minimize interference with wireless signals."

https://www.hdmi.org/manufacturer/hdmi_2_1/index.aspx

The Ultra High Speed HDMI Cable supports the 48G bandwidth for uncompressed HDMI 2.1 feature support. The cable also features very low EMI emission and is backwards compatible with earlier versions of the HDMI Specification and can be used with existing HDMI devices.


Again, not a vendor or installer etc, so I don't know what is or is not on the market yet (I'm assuming the 48g Ultra High Speed cables are NOT available yet, since there aren't really any players etc that support/need it)...

But it appears there is a difference between Premium Certified as it currently stands, and the (upcoming?) "Ultra" High Speed??

And there is no tester for such cables too.

Yeah. Additionally, looking around the HDMI site, I can find "Certified Premium". And I can find "Ultra High Speed".

I CANNOT find any "Certified Premium Ultra High Speed" cables as Jibucha keeps mentioning. Nor can I find anything stating that such cables already exist. Nor anything related to tester/testing for those 48gb Ultra High Speed cables either. There is a mention of Ultra High Speed cables for marketing names when the time comes. The only testing mentioned is the first/early wave that tested 2.1 compliance for eArc. With "additional features added in the coming months" as well as to contact your individual ATC to find out when they will be offering whatever testing is available.

Again, from the HDMI Licensing admin site that he keeps referring to (but never directly quoting or providing links to).

So, looking at the HDMI Licensing, seems like you guys have more than answered all of his questions, AND, he's just maybe pulling tiny bits of actual information, and just drawing his own, inaccurate conclusions around those.

[Kris Deering]

I had a conversation with one of the high ups at a high end cable company last week. He called to discuss 8K and the new HDMI standard. He said they are getting extremely frustrated with the HDMI organization as there is NO testing standard at all for the new format. He said that so far the whole thing is a bit of a cluster#($@

[sapiendut]

Yup. That’s why I’m ignoring his post. I try to help and give the relevant information based on today’s real life technology but he wants to argue for the sake or arguing.

[jibucha]

thank you (quite interesting)

• first :: i will be 'following up/updating this particular post' for several reasons
• thank you :: you have posted some good information from HDMI Licensing, which is helpful (to many?)
• yes :: "it appears there is a difference between Premium Certified as it currently stands, and the (upcoming?) "Ultra" High Speed??"
• Premium Certified :: for forthcoming Premium Certified Ultra High Speed Cables, Certification is 'required' without exception (passive cables to 3M)
• Premium Certified :: for previous Premium Certified High Speed Cables, Certification 'was not required', so finally, HDMI (generally - going forward) will become far less confusing and far more reliable (for everyone)
• regarding active cables beyond the 3M (passive cables testing as required) at this point in time, no certification/testing is planned
• i myself am also struggling to confirm/determine current availability (Premium Certified Ultra High Speed Cables (to - 3M) "I don't know what is or is not on the market yet"
• this reference is to Premium Certified High Speed Cables (18/gps) and not to the Premium Certified Ultra High Speed Cables (48/gps) - - - "Cables are tested to ensure they support the full 18Gbps bandwidth from the HDMI 2.0b specification plus an EMI test to ensure cables minimize interference with wireless signals."
• note :: while there is a wealth of information available from HDMI, definitely it can be confusing determining/finding it (not a critic of HDMI)
• i appreciate your post which i found quite interesting

[jibucha]

correct :: and in their documentation they explain why (keep reading)

• and, 'they clearly explain why' :: I CANNOT find any "Certified Premium Ultra High Speed" cables
• not even close :: "seems like you guys have more than answered all of his questions"
• not so :: "he's just maybe pulling tiny bits of actual information"
• really? :: "just drawing his own, inaccurate conclusions around those"
• you need to read more and post less

For what its worth Monoprice is selling their new 48G cables. I bought a couple pairs to test them out.

https://www.monoprice.com/category/c...talProducts=55

[sapiendut]

It’s absolutely impossible to test 48 gbps cable because there is 48 gbps tester. How many times this needs to be said?

[LordoftheRings]

It doesn't really matter because it's not certified.

Anyway for the Panasonic 9000 and 820 this is all you need (this one's certified):

Or go longer (6 footer) for 60 cents more:
• https://www.monoprice.com/product?p_id=15428

I love HDMI 8K discussions but those Panasonic players are only 4K, they don't even upscale to 8K.
