OLED C9 - EDID / limitation regarding HDMI-eARC pass-through UdoG Posted on 2019-05-24 07:15:55 OLED TVs Vote Up0Vote Down

UdoG, I will be getting an 4K Fury adapter on Monday and was wondering what settings you used on the adapter when you connected it between the C9 and you AVR?

I am very interested in this as well as I will be connecting my PC direct to the TV using eARC to an Onkyo TX-RZ830. I will also be buying an HDMI 2.1 GPU when those become available.

I wholeheartedly support the request to implement proper multichannel PCM support for eARC. There's many scenarios where this is useful/needed. I hope LG will support the full eARC implementation.
Thank you.

Sorry, I sold my 4K Fury - with the hope, that LG will fix this soon.

Throwing my hat into the ring on this limitation as well, multichannel LPCM support would be greatly appreciated for Xbox One X and Nintendo Switch gaming. (found out to my dismay last night that I had to run my Switch through my AV receiver for surround sound)

I  just spent over $6k on the 77 C9, so I hope LG can resolve this quickly with firmware and allow all multichannel uncompressed LPCM signals to be passed via eARC without any HDMI CEC interference. Thank you!

Multichannel LPCM would be REALLY helpful...

@JamalofLG

Any feedback from your Engineering Department?

Please keep us informed.

Thanks!

I'm also extremely interested in this fix.

On a related note, does anybody know if one can use Custom Resolution Utility to achieve the same EDID spoofing as the HD Fury? I've seen it mentioned elsewhere, but so far failed to get multichannel LPCM eARC passthrough working.

I've tried CRU to spoof the EDID, the result is that Windows thinks there are 7.1 channels and tries to send audio to all of them, but the AVR still only sees the FL and FR channels and sound only comes through those channels.

I am not sure whether the HD Fury actually fixes the multichannel LPCM issue, as the people who have used it (including rtings.com) appear to have had slightly different issues and achieved different outcomes. Not sure if @UdoG can confirm whether they got multichannel LPCM working via eARC before returning their HD Fury?

Stickybeak

Ah, that's consistent with my results.

No update yet. Still awaiting a response. I will follow up with you once I get more information.

Add me to the list of people looking for improvements on the eARC side. Bought a 65in C9 over a C8 for eARC support. 

Right now the TV with apps (Emby/Plex) will passthrough Atmos with Dolby surround but not Atmos with TrueHD.

Thanks @JamalofLG it's good to see LG engage with its customers.

peterjcat

This is a good point, it would be great if the internal TV apps would take advantage of eARC. At the moment I can’t play any HD audio even from USB.

Would love to see a better (more complete) implementation of eArc.
