      Is it right that in theory dynamic HDR can be sent over HDMI 2.0a as long as the data stream doesn't exceed 18gbps?

      Hi mark , Thanks for this
      Please elaborate on your comment below please
      "The new specification will be available to all HDMI 2.0 Adopters and they will be notified when it is released early in Q2 2017."

      Are you saying manufacturers will be able to prepare for hdmi 2.1. Steve feedback from pana is that it is possible and from hdmi that upgrade path is within manufacturing control/capabilities should they wish to do it (chipset and bandwidth permitting)

      My hope is that all top sets with hdmi2.0 from 2016 and 2017 could be upgradable via firmware to 2.1

      Any way we can get confirmation in the coming months please ?

      That means that manufacturers may upgrade their license from HDMI 2.0 to 2.1.
      A fairly simple application form process.

      It is not possible to upgrade a HDMI 2.0 chipset to 2.1 with firmware.
      There are major chip design differences.

      You are right Andy but read below. We should be ok for top 2017, not sure for 2016 ones...even if the zd9 Dolby vision chipset was well hidden deep within the Sony when nobody believed it..

      Best answer is Steve w. Answer :
      Craig mentioned to me after the interview that Panasonic could upgrade their HDMI 2.0a inputs to 2.1 if they need to, so that's true. I spoke to HDMI today as well and they said that there's no reason that you couldn't upgrade 2.0a to 2.1 assuming that you use the right chip sets and build some headroom in, so it's entirely down to themanufacturers.

      What it means is that from q2 17, the hdmi2.1 spec can be applied. If manufacturer plan for it (hopefully and big if indeed), should be a simple firmware update...

      So all 2017 HDMI 2.0a can be upgraded to HDMI 2.1 at a later date via a firmware upgrade but this would not be possible for "existing" HDMI 2.0a, as this needs a different chipset installing in advance...sorry if I sound a bit thick but I just wanted to clarify

      If it is the case that we have to upgrade again, I'm guessing it will be a few years before 4K is the standard - never mind 4K 120fps etc...

      No, like Andy said, it is not possible
      However, since spec is known, some manufacturer can do that if they use right chipset and bandwidth...
      That means unlikely for 2016 and possible for some of 2017 models. The pana one seems to be the first evidence
      We are in unknown territories here but there is hope.

      Thanks for the clarification Goldorak

      In all honesty, I only got round to upgrading my amp to 2.0a last year, so by the time 2.2 or is being rolled out, I'll probably get onto 2.1!

      Hopefully I won't be missing out on anything significant in the interim...

      Your Welcome
      I don't want to jinx it but confirmation from pana oled is encouraging. These guys are like politician, before they announce it at ces like they did, it must have been known for months and months

      I can't wait another year and confident that top of the range 2017 model should be upgradable. Not sure about the 2016 ones.
      This statement should make lots of people stop and reflect before jumping on 2016 models from now on. It may make perfect sense financially and 3D,... BUT hdmi 2.1 is also an important factor for the future. This is especially true if the sets are kept for years and years...

      There is no right or wrong, just good to know

      Surely it can't be long before a switch to an fully optical connection?

      If any of the current (Yet to be on sale) 2017 HDR aimed panels can't be upgraded to HDMI 2.1 via firmware, i'd say that would be a massive problem.

      I just can't see that happening, otherwise every early adopter will likely avoid and most of the general public will be faced with online reviews telling them to steer clear this year... Sure there are allot of people who buy TVs blindly - but also allot now a days who use online reviews as a steer for large purchases like a TV.

      The main thing will be whether 2016 models can get the upgrade. I've got my fingers crossed that my KS7000 will do. I personally reckon any 2016 Ultra HD Premium certified (or at least least meet those requirements if not certified) will get a firmware upgrade, just my hunch.

      I like your optimism and genuinely pray that you are right...
      Experience tells me otherwise, I see it happening on 2017 top sets but not the vast majority since average joe doesn't understand it or care much
      As for 2016 sets, wait and see

      Why did they stop at 8k60hz if we will have 4k120hz by then?
      Doesn't make sense. By the time 8k comes along HFR should be a common feature by then.

      This is a very " forward looking" spec in the sense that it restores the headroom that used to be available circa 2009 , where all chips were 4096 x 2160 @30fps capable but such content was years away and UHD went with a different res anyway.
      There is nothing immediately on the horizon that will use this extra bandwidth.

      HFR is being talked about, and might just make headway in gaming content, but has received nothing but hostility in movie content.
      Remember the Hobbit an unexpected journey?
      Otherwise , 8K is a long long way away, if it ever makes it at all.

      I wouldnt worry too much about 2.1...the only people that should stress are suckers like me who have to work with it and get compliant...consumers should be shopping for features not chip numbers, manufacturers are not allowed mention them in specs in any case.

      Wow - 8k already. It's not case of running before you can walk, more like running before your conceived! 4k is still in early infancy, with barely any content, yet now we'll all be told we need 8k sets. Unbelievable.

      2.1 is a big deal for me Andy as I don't change TV every 3 years. Will probably take me 2 just to pay for mine :)
      When I invest, I go relatively high and hope I can reap the benefits for at least 5 years... I try but don't always succeed.
      Things are maturing now and we have choice...not too much asking they pave the way for 2.1 in 2017 sets

      So what is the benefit in hdmi 2.1 on a 4k screen ?? im happy with 60 fps, i guess if it can pass dolby atmos, dolby true hd DTS HD and DTS x via arc thats a plus and obviously hdr 10 with meta data is a plus but thats the only benefit i see on a 4K screen

      Every manufacturer should put clear guidance on their websites detailing what models are upgradable and which models they will upgrade. Only such a position statement will keep us all satisfied.

      I can see 4k 120Hz being useful for a few gamers but 8k TV, in my view, will be pointless for consumer TVs. We barely have any 4k content and even that is a mixed bag. Can you imagine how crap SD or even HD would be on a 8k panel?

      By the time 4k becomes common as 1080p some other standard will be thought up by tech companies!

      I only read “Game Mode VRR features variable refresh rate, which enables a 3D graphics processor to display the image at the moment it is rendered for more fluid and better detailed gameplay, and for reducing or eliminating lag, stutter, and frame tearing.”

      I am on board for that, no more stutter like free sync on PC monitors, bring it to consoles and that would be fantastic.

      It's a shame that it was announced alongside this years products as it's leading some to believe a) they need 2.1 and b) anything on sale in the near future will get it. That's inconceivable and in fact pointless unless the TV needs something it provides - and sets that do are a way off, not to mention the 48 Gb/s cables and AV amps, and sources.

      Not to mention what we can actually see! As Phil has mentioned before, he's struggling to notice the difference between FHD and UHD (in terms of resolution) on a 100"+ screen. Most of us don't even have a 65" screen and are sitting much more than 10' away from it, so what's the point? My side-by-side res tests tell me the same thing, I can hardly notice. Equally I'm not sure about the benefits of excessively high frame rates beyond 60 FPS, and whether it's just another placebo effect. I'm sure HDMI 2.0a will serve me well this year, and for many years to come. It's also good to know that a standard has emerged today that just might be required to cater for my needs in say 8 years time. By that time wireless HDMI will probably be talking to contact lenses.

      And pigs will fly.

      Manufacturers are obscuring information as much as they can.

      Only thing that is important at this time is HDR10 with dynamic metadata (can't believe that was not in the mandatory specs from the beginning).
      And if HDR10 with dynamic metadata will require HDMI 2.1, it will fail BIG time, as 2.0a was pushed hard by the manufacturers to be the HDR proof connection. Maybe this is why Dolby Vision is popping up everywhere (since it can handle dynamic metadata on 2.0a).

      Am I right in thinking that dynamic metadata for HDR is a big thing for projector users as no pjs yet come close to doing HDR properly as things stand?
