    Ooh standardised VRR on a consumer hdmi socket. Hopefully Intel will adopt it and that will end the Freesync/Gsync nonsense.

    Maximum cable length "about 2 to 3 metres" from the FAQs but no tech details about the cable itself.

    Re: HDMI v2.1 spec released with 10K and Dynamic HDR support

    Some decent stuff in there like VRR, eARC and QMS but the odds of any existing 2.0 displays getting soft updated to 2.1 seems very unlikely given the TV industry's desire to sell more gradual updates to TV's.

    If LG 2017 OLED's got the big ones like VRR and eARC there would be little reason to buy a HDMI 2.1 2018 or 2019 model.

    It's a pity TV's don't feature Displayport, a much more forward thinking interface, does most of what HDMI eventually catches up to years later but of course to some that is be design to sell more TV's.

    we will be charged silly monies for the new HD cable just like they done when it first came out.

    But there will be a premium. Carrying that amount of data does require very high quality cable even over short lengths.

    Yeah a premium straight into the company profits there's a lot of GREEDY companies about just look at APPLE,GOOGLE,ADOBE,SONY,STARBUCKS, THE LIST IS ENDLESS AS EVERYONE KNOWS

    this spec is getting way too much hype that it doesn't deserve. 8K @ only 60Hz ? hello, they have the tech to allow native 8K @ 120, do so! this spec is a let down. now we have to wait another 5 years before 2.2 that supports 120HZ? this is LAME. this is yet another slow to the table disappointment.

    Are there any displays on the market capable of displaying 8k at 120hz? Is there any media available at that combination?

    How dare these companies gain a return on their investment in developing these standards and products! . Still, you don't have to buy one - it is entirely optional!

    Not on the market, but possible:
    https://www.anandtech.com/show/10732...000-ppi-for-vr
    There is prior art of commercial products multiplexing across two DP cables:
    https://www.blurbusters.com/4k-120hz...d-480hz-modes/
    So 8k at 120 Hz will be possible with 2 HDMI cables meeting this spec easily enough, once someone makes a suitable monitor and media to run on it

    Implementing the hardware for 8k @ 120 Hz would be a pointless waste of money when 4k @ 120 Hz content & screens are non-existent at retail, of course

    Tech specs of the cable are scant (in terms of construction) but it wouldn't surprise me if the new standard incorporated a pair of coax cables with the signal multiplexed across the two.

    The bandwidth alone is pretty amazing TBH. It's gone up from 18 to 48 GBit. No wonder they need a new cable. The original HDMI had a tenth of the bandwidth.

    The whinging elsewhere on this thread shows a fundamental misunderstanding of the relationship between gigabits and pushing pixels at decent colour depth at a decent refresh rate.
