      HDMI 2.1 is not fibre optic by default. Belkin have a copper HDMI 2.1 cable.
      Xbox One X and LG's new 9 series lineup support HDMI 2.1.

      No Belkin (and Apple) have an overly enthusiastic marketing dept who have gone around in circles renaming and describing a 2m copper cable which they launched long before the new Ultra High Speed certification was agreed, announced or possible.

      Belkin call it an ‘Ultra HD High Speed’ cable - I guess that gets around it not carrying the HDMI.org ‘Ultra High Speed’ logo or certification.

      There is no HDMI certification which uses HDMI Version Numbers.

      Hello Joe, youre wrong here, Belkin has 2 sorts of HDMI cables.
      ( excluding the 2018 model, and the ones below 18Gbps )

      One is called: Belkin Ultra HD High Speed HDMI cable
      ( 18Gbps supports 4K 60 Hz ), launched before the new Ultra High Speed certification was agreed.
      AV10168BT2M-BLK

      The other one is called: Belkin Utra High Speed HDMI cable
      ( 48Gbps 4K 120 Hz or 8K 60 Hz ), launched after the new Ultra High Speed certification was agreed.
      AV10175BT2M-BLK

      I guess the printers haven't received the Certification Logo art work from HDMI.org and the web dev team haven't received the naming changes :)

      There's no Certification program Logo for Ultra High Speed cables, only for the High Speed ones...
      https://www.hdmi.org/manufacturer/premiumcable/Premium_HDMI_Cable_Certification_Program.aspx

      Now you can check (click on the link) if a company like Belkin or any other, is a HDMI 2.1 adopter...
      https://www.hdmi.org/learningcenter/adopters_founders.aspx

      And yes, the Belkin website is a complete mess :laugh:
      But when you look in the Apple store, the information is correct.

      Website a mess - I think we all fall foul of that one :)

      Ultra High Speed - there is a new Logo and Certification programme, though not aware of anyone claiming to be 'Ultra High Speed' certified as yet.

      HDMI :: Manufacturer :: HDMI 1.4 :: Finding the Right Cable

      HDMI Adopter and HDMI Cable Certification are separate programs - most cable 'brands' rely on someone else to manufacturer and certify the cable assemblies they supply as it is hugely expensive to have cable/cable production lines certified.

      Hi Joe

      A few years ago I purchased my High Speed with Ethernet HDMI leads from a link you sent me.
      I now have a Panasonic 55FZ802 Oled, Panasonic UB820EB 4K UHD player, do i need to go for High Speed Automotive HDMI Cable as a minimum ?

      Unless the 4K UHD signal is not working or has very obvious issues (drop out, flickering, sparkles etc) there is no need to change out the current cable.

      I have plenty of 'legacy' HDMI cables (many pre date High Speed Certification) which will carry a 4K UHD signal, cable length is usually the main problem for a 4K signal.

      I'm using an old QED cable from my receiver to my FZ802 with Sky's own supplied cable from the SkyQ box to the receiver with no problems.

      I agree wih Joe on all accounts. Cable mfrs are pretty much free to make whatever claims they want with carefully worded ads and slick marketing. Belkin just changed their product numbers and marketing. There are no certification programs for HDMI 2.1 compliant cables. The only thing the Belkin cables have been shown to "comply" with is the length for HDMI 2.1 which is defined at a maximum of 3m (9'). If the cable works, fine, but at this point in time there is no way to prove that any of the other HDMI 2.1 hardware options are, or can be supported. Pure marketing at its best. HDMI.org has not registered the name "ultra" to differentiate 18Gbps cables (registered as Premium) for the 48Gbps cable. Caveat emptor.
