OK I managed to load up the HDFury DIVA codes to my Harmony One (ancient I know) and get my other learning remote (Fire TV SideClick) so I can select inputs with iR.
On another note there are 3D Printer link in the firmware download area…I am thinking to get one done, but more will make things less than a one off. Anyone else interested?
FRL differs from the traditional TMDS signaling of previous HDMI versions (HDMI 2.0 and below). It defines signals by the number of lanes and their combined lane rates and has six possible FRL rates consisting of three to four lanes with a lane rate of 3-12Gbps (see table below). Notably, FRL will always attempt to maximize throughput based on the sink capabilities and, ultimately, the link (cable) maximum capacity using link training and each lane maintains a fixed data rate rather than the previous HDMI versions varying data rate TMDS Channels. Also, FRL embeds the TMDS Clock Channel directly into the HDMI Signal, allowing for features such as Variable Refresh Rate, Dynamic HDR, and more.
However, HDMI 2.1 is not entirely different because FRL is backward compatible with lower data rates and will fall back to traditional TMDS if FRL is not supported. When in fall back, TMDS is capable of all signals up to FRL2. Although a device may support a particular FRL rate, it might not support all possible video signals.
FRL 5
FRL 6 is where 48gbps is required, long way to go… but soon…
We can’t even get 40Gbps to work at full bandwidth, let alone the theorised 48Gbps. Even if a source is capable, the display may not. And we already know HDMI cable also played an important role to link up the source and the display. I’ll remiss not to mention the edge rate compatibility of the cable itself etc. The dust haven’t fully settled and there we have another new add-on to the HDMI 2.1a standards. The advent of HDMI 2.1a is coming soon. HDMI 2.1 standards is a mess imo. Some of the features can be missing from the specs BUT manufacturers of source or display is not obliged to reveal this in the tech specs.
