Yes, eARC is a game changer, it will NOT rely on HDMI-CEC for the following functionality:

1. device discovery
2. device capability enumeration (AudioEDID)
3. it enforces the Lip Sync Correction (optional for classic HDMI-ARC)

HDMI-CEC is still used for:

1. Mute and Volume Control
2. Devices Power Control
3. Classic HDMI-ARC
4. Fallback if no eARC or eARC fail

The 2020 models from Denon and Marantz will all have HDMI 2.1 ports! I am sure that Yamaha will do the same because it has delayed new models for 2019, just like Denon and Marantz, in preparation for HDMI 2.1.

Your problem may be caused by a Denon X4500H miss-configured Sound Mode. Check/change the Sound Mode for the TV input.

Thanks for the input. I verified that the Movie Sound Mode was set to DD+ Dolby Atmos. Also tried other movie sound modes as well as Auto when using the Pure button.

My apologies if this is getting outside the scope of this thread.

You can overcome this "software" limitation by using something like HDFury Dr. HDMI 4K to add the AudioEDID for LPCM 8 channels for the TV eARC input.

Be aware that the HDFury Dr. HDMI 4K is just an HDMI 2.0 device, not HDMI 2.1!
With this being the first year and really no other devises plugging into the TV that are HDMI 2.1 you bet there will be limitations and probably more to come.....

Thats probably the reason why LG responded to this petition.

This time I do not see a lot of people caring about this issue.
But this does not mean that we should not try.


If someone is going to start a petition about the eARC Multi-Channel-PCM I am totally aboard.

I would be in as well. Also, we might be able to get through on their forums. For example, over on this link, they discuss the VRR issues at length. https://lgcommunity.us.com/discussio...led-vrr-issues

AVR-X1xxx/X2xxx series announced in May, available in June;

AVR-X3xxx/X4xxx series announced in July, available in August/September;

AVR-X6xxx series announced in September, available in October;

There is some variability of dates, of course.

Miles better on everything except a black screen. Oled black is black. But everything will be dramatically better.

I don't own a C9 but do have a 55 inch C8 and did own a 9300 before it..I know the C9 will beat it in every way but the 3D of the 9300..did love that on there..HDR really makes up for the lack of 3D

That Forbes guy John Archer seems to have a direct line to LG, over the past few years whenever he brings up something LG respond.


Making him aware of the lack of PCM 7.1 support over eARC might be an additional way to go.



He's gotten a reply out of LG with regard to the VRR bugs and a fix is in the works, though it seems to me no-one at LG did any thorough testing of VRR before launching the product or even bothered to add Freesync support so PC's could be used with it



Hopefully these issues get ironed out.

Great idea!!!

I have written to John Archer:

Quote:
Hi, thank you for your C9 review! I just want to tell that we discovered that the C9 has a limitation regarding HDMI-eARC pass-through, it seems that LG did not enable the AudioEDID for LPCM 8 channels, just the standard LPCM 2 channels. The LPCM 8 channels are very important for multi-channel audio from game consoles and PCs because not all games/content are using compressed HD audio (TrueHD+Atmos - this works just fine via eARC). The limitation is not in the hardware, because if you modify the AudioEDID of the LG HDMI-eARC port with an HDFury adapter the TV accepts the LPCM 8 channel audio and is passing the audio to the AVR, unmolested (as RTINGS did discover in their C9 review). You seem to have a special relationship with LG, they listen to you and if you are kind, please pass this information to LG, maybe they enable this AudioEDID in future firmware, greatly expanding the usefulness of the eARC feature with a minor modification. Thank you very much!

Lip-Sync Issues

I’m having a lot of lip-sync issues with the LG C9 connected to my Sony soundbar (HT-X9000F) when using HDMI ARC. I have eARC ‘On’ in both the C9 and Sony soundbar settings.

The soundbar goes straight from HDMI ARC to Input 2 on the C9 (ARC). With Xbox connected straight into the TV, there is noticeable lip-sync problems when using any of the apps (games, youtube, Netflix, HBO Go etc.) Xbox audio is set to Bitstream.

I am very surprised by this since eARC is supposed to completely eliminate any lip-sync issues. The only way to eliminate the lip-sync issues is to run the Xbox thru the soundbar instead of straight into the C9, but then I lose ALLM and VRR capability. Apparently the soundbar can’t pass those features through it.

Another weird thing...with the C9’s built-in Netflix and youtube apps, I get a perfect sync with Netflix, but there is an A/V sync problem with youtube. Again, this is while using the ARC connections between the Sony soundbar and C9 with eARC enabled on both. Is anybody else having this problem? Isn’t eARC supposed to enable a perfect A/V sync?

LG C9 65”
Panasonic UB820
Sony X9000F soundbar
Xbox One S, PS4

eARC enforces Lip Sync, but not every audio codec has support for this or that the provider/app enabled the Lip Sync flag... Most Lip Sync problems are with AC3 and AAC codecs (with mangled of missing Lip Sync flags), but there are others as well...
HT-X9000F had eARC added by a later firmware update. Maybe Sony's eARC implementation has some bugs?
ALLM pass-through not working is weird since ALLM is way less complex than eARC to implement.

Did you check for newer firmware for the soundbar?

BTW is there any point in waiting for receivers with HDMI 2.1, when they already support eARC? It's not like you will need any extra bandwidth considering that you can now connect every video outputting device to the TV directly without audio return issues.

As we've seen over the last pages, currently the LG is not able to relay uncompressed PCM Multichannel audio via eARC to an AVR from any source like Xbox or PC since it's EDID does not show PCM Multichannel as supported. So, if you want to use that - provided LG doesn't fix it with an EDID update - you'll need an HDMI 2.1 capable AVR.

Yeah, the soundbar has the latest firmware update released (4/2/19) which added eARC. It is very possible that there is a bug, although I still get A/V sync problems with eARC disabled.

I’m absolutely loving the PQ on this C9, but I never had any A/V sync problems with my previous TV (Sony x900e) and devices connected to it while using the soundbar. It makes me think maybe there is some bad crosstalk happening between the Sony soundbar and the LG TV.

I’ll be pretty disappointed if it turns out that I can either have ALLM/VRR or perfect A/V sync, but not both if I want to use the soundbar. I have a very small space to work with so a full surround setup is not really in the cards. A soundbar is as good as it gets for me.

Rtings.com says it’s 0 in their C9 review. Not sure if it’s correct?

I just want a neutral setting with no softening or sharpening. Is it at 0 or 10 on LG OLED?

Has there been a change made by LG from C8 to C9 regarding the default OLED Light setting for DV?
(or am I imagining things?)

I’m sorry for quoting myself. Can any of you answer two questions above?

I also included a link to the RTINGs review and to this thread

If I get a reasonable reply I will inform you.

I was able to get the issue resolved by doing a factory reset on the TV. Once I set things back up Netflix now shows Dolby Vision and Atmos. Thank you very much for your help.

Has there been a change made by LG from C8 to C9 regarding the default OLED Light setting for DV?
(or am I imagining things?)


This has been changed on the C9.

I’m pretty sure my TV outputs LPCM 7.1 from my PS4 from the TV HDMI ports or through my soundbar. (Z9F, eARC on)

Why are you guys saying it doesn’t?

If you have not set up your sound bar's connection to the C9, that's something that you need to do. Go to All Settings -> Connection -> Device Connector ->, click on Bluetooth/Sound Bar, then follow the prompts.

We're saying the LG doesn't. No one said anything about a Sony Z9F. And pretty sure doesn't mean you know for a fact - is there any way for you to confirm?

I completed that setup and it didn’t help with my A/V sync troubles.

Finally got a chance to watch some Game of Thrones (not caught up to the finale yet) on my 77C9, and wow! It is so much cleaner looking than watching on my 55E6, which is kind of crazy too because you'd think the extra size could really bring out some compression flaws. I'm using the same 4K Amazon Fire TV and watching on ISF Dark without any special image processing on other than True Motion set to Clear. I'm impressed and I wish I could have experienced all of the seasons in this quality.

I know quite a few of you posted how much cleaner GOT was on the C9 and wanted to second that, even for the larger panel size. I'll also second that motion and the motion interpolation options are greatly improved over the E6 as well.

NBA Playoffs on TNT streamed via Playstation Vue looked pretty similar to my E6 (Vue offers mediocre picture quality similar to Cable IMO), which I expected, yet the size increase did not make it look worse so I think that's a win. I did not try messing with any AI or other processing.

Does anyone know how long it takes for WebOS versions to spread worldwide? For example I see the US and UK have version 03.50.31 (for some reason in the UK it looks like 03.50.29 has a newer release date) for the C9 but here in Aus we've only got 03.50.29. Or they the same thing just different version numbers for different regions?
