I have my projector connected to Monitor 1, fine.
I have a headphone audio processor that requires multi-channel HDMI input. When I connect that to either Monitor 2, you have to switch the Denon to output audio out of the HDMI, which it calls “TV”, and you get 2 channel.
When I try the Zone 2 HDMI output, that is also stereo!
I can’t believe Denon’s flagship cannot ouput multi-channel audio over HDMI!!
Please tell me I’m missing it and it’s possible.
As JDSmoothie said, there are quite a few limitations to take into account. Selecting TV out is definitely a no-no if you want to keep multi channel.
I have solved it that way:
HDMI 1 OUT goes to my JVC RS500 through a HD Fury Vertex that reports a "full Audio" capability back to the AVR, which deals with the limitation induced by connecting a PJ to the AVR. You *might* be able to send the second HDMI Out of the Vertex (it's a 2 in / 2 out) to your HDMI Headphones.
For some reason that I can't remember, I'm using the HD Fury AVR Key on the HDMI Zone 2 out to take the full audio and send it to my HDMI Sony headphones without downgrading the signal to stereo for the other HDMI Outs.
I would ask HD Fury in the Vertex thread to confirm what you need, but I can vouch for both products, I use them all the time and that definitely resolved the issue here.
Alternatively, HD Fury should release in 2019 a couple of new devices (Maestro/Diva) that will definitely handle everything and replace the Vertex/AVR Key combo.
I assume that, like my Sony, your HDMI headphones are HDMI 1.4 and not HDMI 2.0, so your should keep that into account as well because beyond the audio limitations to stereo, you will also get the video limitation to HDMI 1.4 bandwidth (10Gb/s instead of 18Gb/s) if you don't put the headphones on a separate path, with a HD Fury device to keep reporting full audio / full video to the AVR.
