I have my LG C8 television connected to my Denon X3300w amp using a Celerity DFO HDMI over fiber cable.
Reason for this is that my television is mounted on a wall with nothing beneath it.
The cable length I need is about 8 meters however the tubes in the wall are too small to fit a regular HDMI plug, hence the DFO cable which has detachable plugs.
Now it has been working great for years with the cable supporting the full 18gbps and no CEC issues at all.
The only issue I bumped is to when I try to play Netflix or Disney+ content on my TV with the audio over ARC the cable loses sync.
When playing my own movies on the Plex app with Dolby Digital 5.1 (AC3) it works great though.
The problem with Netflix/Disney+ is that they seem to use Dolby Digital Plus (e-AC3) which requires more bandwidth, especially with the Atmos metadata.
Now I've emailed Celerity and they can confirm the ARC bandwidth on their DFO cables are limited to approximately 6Mbit.. not enough for DD+.
So for DD+ content I have to switch my ARC output to PCM in the settings menu of my TV, getting only stereo lol.
They do have a new product called UFO but they have bigger heads which I don't think can be feed through my tubes.
So I was wondering whether there is another HDMI over fiber solution which:
- has detachable heads so I can feed it though my tubes
- support the full 18gbps for the HDMI 2.0 standard
- offers the bandwidth for DD+ over ARC which I believe is like 30Mbit
- has no CEC issues like dropouts or only supporting certain fixed addresses
For the record I'm not talking about e-ARC or lossless audio.
Just DD+ with optional Atmos over regular ARC.
