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. ![]() Source: The Tech Report |
I would be more interested in HDMI 2.0a. 2.0 is like an interim standard, 2.0a will allow protected content, 10 bit, 12 bit HDR and more importantly Chroma Subsampling of 4,4,4 vice IQ degrading 4,2,0 of HDMI 2.0.
http://www.paradetech.com/2015/08/pa...ol-converters/ HDMI 2.0 basically allows degraded image quality at 60fps on 4096x2160 UHDTVS. About Chroma Subsampling: http://www.5dfilmmaking.com/tut_444.htm |

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. http://hdguru.com/hdmi-2-0-what-you-need-to-know/ http://hometheaterreview.com/what-yo...about-hdmi-20/ |
Confusion

http://www.anandtech.com/show/9152/f...-hdcp-and-hevc 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. |

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. |
The adapters seem to be feature complete.
