TMDS
TMDS is the signalling method used by this HDMI generation to carry high-speed digital video data. Vertex handles the full 600 MHz HDMI 2.0 TMDS class.
TMDS is the way HDMI 2.0 and older send the picture data as fast electrical pulses through the cable.
It uses three data channels plus a clock.
The Vertex handles TMDS up to 600 MHz, which equals 18 Gbps.
Does the HDfury Vertex use TMDS or FRL?
HOW IT WORKSTMDS only. The Vertex handles TMDS signals up to 600 MHz (18 Gbps), the HDMI 2.0 maximum. It does not support FRL, the HDMI 2.1 link used for speeds above 18 Gbps.
How to use it with the Vertex:
- Read the TMDS clock of the current signal on the OLED Info page, e.g. 594MHz (p.19).
- The RX INFO page shows pixel clock and TMDS clock side by side (p.19).
- For 600 MHz signals use 600MHz/18Gbps certified cables, ideally 6 to 12 ft (p.104).
What it is
TMDS is the signalling method used by this HDMI generation to carry high-speed digital video data. Vertex handles the full 600 MHz HDMI 2.0 TMDS class.
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
Is 600 MHz the refresh rate of my screen?
No. 600 MHz is the TMDS clock of the HDMI link; the refresh rate is how many pictures per second you see, like 60 Hz.
What replaced TMDS in HDMI 2.1?
FRL (Fixed Rate Link) for speeds above 18 Gbps. The Vertex does not support FRL.
What does 297 MHz or 594 MHz on the OLED mean?
That is the TMDS clock of the current signal, shown on the Info page (p.19). 594 MHz means the link is running near the Vertex maximum.
