New HDMI 4k@60Hz Splitters

May 30th 2019 – Split HDMI Audio and Video.

Quite a few times been asked why HDMI out of a splitter port into receiver for audio isno go and HDFury AVRKey is the answer.

HDMI signal path – any device which sits between a Source and a Sink (Display) is called a Repeater (that may be an AVR, HDMI Switch, HDMI Matrix, HDMI Extender…) and must support the same range of signal formats and HDCP version as the Source and Display maximum capabilities if you want to get the best out of your system.

Where you have a ‘legacy’ AVR (capable of 1080p, non-Atmos with HDCP 1.4) sitting in the middle of an all 4K UHD, HDR with Atmos audio system it will limit what audio and video the Source can send to the Sink (Display) and AVR.

The HDFury AVR key ‘isolates’ the Source and Sink (Display) from the legacy AVR so the HDMI cable from the AVR key to the Sink (Display) carries full capability Video and the second HDMI cable from the AVR key to the AVR carries the maximum audio quality the AVR caters for.

Within an HDMI signal there are no dedicated Audio lines, the audio signal is encoded into the video signal which means the AVR must ‘see’ a Video signal it understands before it can lock to and decode the audio, the AVR key replaces the 4K UHD video signal with a ‘dummy’ blank image at 720p or 1080p with HDCP 1.4 on its ‘AVR’ Output so that the AVR can ‘lock’ to the signal.

Vertex just scored 9/10 on AVforums review

Simply one of the best score ever ! Excerpt below:

“The HDFury Vertex is the Swiss Army Knife of HDMI, and is capable of solving a multitude of problems that can crop up with the de facto connection interface of the HD and Ultra HD world we’re in. Let’s not beat around the bush though, the HDFury Vertex is not aimed at your average consumer, it is designed for AV enthusiasts, industry professionals, and content creators.

It can be used with just about every HDMI device in existence and can take almost every HDMI format and scale it to fit the capabilities of the connected display or receiver, thus mitigating the urgency to upgrade components in your setup that don’t tick all the necessary compatibility boxes, but in all other ways are perfectly serviceable.

The Vertex is HDMI 2.0b/HDCP 2.2 compatible, supports 4K/60p and 4:4:4 at up to 600MHz, a bandwidth up to 18Gbps, and promises to solve any signal issue while being able to display full diagnostic information via a graphical user interface or a built-in OLED display panel. It can also handle HDR10, Dolby Vision, Hybrid Log-gamma (HLG), HDR10+, DTS:X, and Dolby Atmos, to name but a few formats.”


“If you have an HDMI related issue, then the changes are that the HDFury Vertex can solve it. Whether it involves scaling a signal up or down, changing the HDCP settings, analysing and modifying the HDR metadata, or running two different resolution displays, the Vertex has you covered. There’s almost nothing this device can’t do with an HDMI signal”


“It can fix just about any signal issue, and is so flexible that this review can only scratch the surface”
