    The adapters seem to be feature complete.

    4:2:0 is a color compressed video signal that does indeed cause degradation. Looks like HDMI 2.0 can support 4:4:4 as an option.

    HDMI 2.0a extends color to 10 bit, 12 bit and HDR - anyways read the AnAndTech article maybe that will be clearer then my confusion aspect of what is going to happen. I just can't see new UHD Blu-Ray players not supporting all those HDMI 2.0 UHDTV's that has been sold in the last several years.
    It's 4:2:0 on the media source but it's decompressed on the output source to 4:4:4 as long as the output source is HDMI 2.0 compliant and the TV has the appropriate HDMI port for it. It'll look something like this:

    HDMI 1 (HDCP, ARC) 4:2:0
    HDMI 2 (HDCP) 4:2:0
    HDMI 3 (HDCP with 3.5mm audio in) 4:4:4 at 60Hz
    HDMI 4 (HDCP 2.2, MHL) 4:2:0

    HDMI 2.0a is too new and no content exists for it yet, and even the next generation UHD Blu Rays will still retain 4:2:0 compression. The goal is for 4k 60fps which eats up bandwidth and space, and the first thing to go to save space almost always the extra color detail that most people can't see anways because most TV's haven't caught up to that kind of color accuracy.

    Confusion

    All Blu Rays (highest quality of any source) ship with Chroma 4:2:0 Chroma subsampling, so nothing is "degraded" over the HDMI 2.0 spec itself.

    HDCP 2.2 also specifies 4K/60 with a 4:4:4 color space, and that is part of the HDMI 2.0 spec. However, you won't see native 4:4:4 content even in UHD, because the chips do a fine job of decompressing 4:2:0 content without degradation of color loss. HDMI 2.0 specifies 18 GB/s bandwidth and that is more than enough for even 7k content.

    HDMI 2.0 basically allows degraded image quality at 60fps on 4096x2160 UHDTVS.

  • Club 3D active adapters convert DisplayPort 1.2 to HDMI 2.0

    Good news for you R9 Fury X owners and others as Club 3D has finally released an active adapter going from DP 1.2 to HDMI 2.0 for some 4K @ 60Hz resolution goodness! The Tech Report has the scoop and the details.


    The Radeon R9 Fury X shipped without HDMI 2.0 support, so AMD's top-end card couldn't drive many 4K TVs and monitors at 60Hz with an HDMI cable. Fortunately, that shortcoming can be corrected with an active adapter that converts a DisplayPort 1.2 port to HDMI 2.0. Club 3D has announced a pair of these handy adapters, one for mini DisplayPorts and one for standard-sized versions.
