    Hello, I am trying to buy an HDMI 2.0a with a length of 20 meters. The tallest I could find is 5 meters. Any help would be appreciated.

    HDMI Cables do not have version numbers they are either standard , High Speed or new premium.

    No cable over 8M will be certified as High Speed.

    WHat are you connecting ?

    Are both the TV and the PC Graphic card HDMI 2.0 HDCP2.2 compliant ?

    What resolution and Frames per second are you looking to display ?

    I suggest getting a good quality 20m cable from a reputable seller, and trying it out, though depending on what you are wanting to send a HDBaseT HDMI over Cat5/6 extender would be a better more reliable option

    At present it is nigh on impossible to provide an HDMI cable which consistently caters for 2160p, 60fps, HDR, 4.4.4 processing at anything longer than about 4m.

    HDBT in its current spec is not going to work.

    A Fibre optic cable is the only realistic option at this time - assuming you are willing to spend the required monies, we have a few in and working as required.

    As Seb says ignore HDMI Version numbers and remember that any claims of 18 Gbps or similar are not verifiable or repeatable to any known/agreed standard.

    HDMI.org have introduced the new 'Premium High Speed' certification program - not many cables around as yet and those I have seen are no longer than 8m.

    http://www.hdmi.org/manufacturer/premiumcable/Premium_HDMI_Cable_Certification_Program.aspx

    If you don't want to go fibre either move the kit closer together, accept the limitations of current cable technology or be ready to spend a frustrating few months trying to find a working solution out of the myriad cables purporting to be 4K ready at 20m.

    Thanks for the reply, Yes both TV and the PC Graphic card will be HDMI 2.0 HDCP2.2 compliant.

    The optical fiber extender would be the best option, if it will keep the quality. Still I think I have to wait till 4k ones come out.

    Thanks again for your help

    2160p,60 is possible with Fibre - 4.4.4 can still be tricky but the latest versions of some cables look like they will do the trick.

    Now it depends also on the price... Maybe its more worth it to buy a 4k monitor also for the PC. Joe, could you please suggest me a good 20m Hdmi so at least I would have the best picture possible with a cable of that length.

    Thanks

    20m sits in the middle of the the 'factory' terminated options we use - 60' (18.2m) is around £240 and 80' (24.3m) is around £290.

    A suitable 4k Display local to the PC is a good option - I have a Dell P2715Q bolted to my iMac (that was around £480).
