Meridian Unplugged - Powered by MrTechGuy.co.uk Forums Discussion Meridian - Systems HDfury Vertex2 vs Vrroom in HD621

The HD621 doesn't know it's getting eARC in the Vertex/Vroom scenario. They both do eARC with the TV and pass it out of TXAudio as a standard HDMI interleaved signal, so it's unlikely to be the HD621 that's directly the problem.

What is most likely is 1) the CDS (which is like EDID for eARC) asking for something the Meridian combo can't handle, or 2)asking only for things that the TV can't or won't (licensing....) provide.

I've heard that HDMI don't allow multi - channel LPCM in eARC, so stereo or DD/DTS core may be the best you can get before it goes into versions of the HD formats we can't decode. You can get those on the TVs optical out with much less fuss....
I hope I heard wrong, or that any such restriction isn't actually enforced in all TVs. I frankly decided that life's too short to be messing around with eARC so I've no actual evidence either way.

There's an NDA for HDMI licensees in respect of the CDS settings, but HDFury did offer to construct a custom one for me. Tell them the exact capabilities of the TV and Meridian system and they'll probably do one for you. It's a shame they don't auto - create a good one from the EDID settings.

Best regards,
