18 Gbps
The maximum HDMI link-rate class handled by Vertex. It is the total data capacity available to transport video, audio and HDMI signalling.
18 Gbps means the HDMI connection can move 18 billion bits (ones and zeros) every second.
Think of it as the width of a water pipe: a wider pipe lets more water through at the same time.
Bigger pictures, more frames per second and more colour detail all need more of that pipe. The Vertex is built for the full 18 Gbps pipe of HDMI 2.0.
Does the HDfury Vertex support full 18 Gbps HDMI bandwidth?
YESYes. The Vertex passes full 18 Gbps (600 MHz) HDMI 2.0b signals, up to 4K60 4:4:4 8-bit or 4K60 4:2:2 12-bit. It is not HDMI 2.1, so 40 or 48 Gbps (FRL) signals do not pass.
How to use it with the Vertex:
- Use 600MHz/18Gbps-certified HDMI cables, ideally 6 to 12 ft long (p.5, p.104).
- Pick an EDID that allows 600MHz formats, for example table 11 '4K60-444 600MHz HDR BT2020 All Sound' (p.15).
- On the TV, turn on its extra 4K 4:4:4 setting on a 600MHz-capable port, such as 'UHD Color' on Samsung (p.103).
- Check the link in the USB GUI top section: RX and TX lines show resolution, colour, bandwidth and HDCP (p.27).
What it is
The maximum HDMI link-rate class handled by Vertex. It is the total data capacity available to transport video, audio and HDMI signalling.
Why it matters
HDMI behaviour is determined by the complete signal chain. Vertex exposes and manages these technical layers so mixed sources, displays, projectors and AV processors can be configured more deliberately instead of relying only on automatic handshakes.
Common questions
Do I need an HDMI 2.1 (48 Gbps) cable for the Vertex?
No. The manual asks for 600MHz/18Gbps-certified "high speed" cables, ideally 6 to 12 ft long, for 4K60 4:4:4 8-bit or 4K60 4:2:2 12-bit (p.5, p.104). A newer Ultra High Speed cable also works, because HDMI cables are backwards compatible.
Can the Vertex pass 4K120 4:4:4 or other HDMI 2.1 signals?
No. Its maximum is 4K60 4:4:4 8-bit, 4K60 4:2:2 12-bit, 4K120 4:2:0 8-bit or 8K30 4:2:0 8-bit (p.110). HDMI 2.1 signals that need more than 18 Gbps (FRL, 40 or 48 Gbps) cannot go through it.
Is 18 Gbps the same as 600 MHz?
Yes, they describe the same maximum. At 600 MHz each of the three HDMI data lanes carries 6 Gbps, which adds up to 18 Gbps.
