FYI - LG just released a firmware update for the OLED line.. Update doc states: "1. Improvement 1) improve the video noise in HDMI HDR 4K input. " Software is here: www.lg.com/us/support/software-firmware-driversFollow the instructions exactly (remember to use a newly formatted USB drive with one folder "LG_DTV" on it)

I need to check when I get time. My LG usually auto-updates.
Last night I spent about twenty minutes mucking around again. Turned system on, no sound. Toggled inputs, nada. Power cycled system, powered TV and cable box on and off in various order, sometimes got sound, sometimes picture, never both. Hit the power switch on the back, problem resolved. This is happening once or twice a month. My system is not configured to allow easy access to that power switch. I need to either make a remote relay, rig up a switch out front, or buy a different processor. Frustrating.
It's been a month or two, wonder about the banding issue?

Post LG software update, I'm not seeing any banding.
You'll need to get the software from the LG support website.

Post LG software update, I'm not seeing any banding. You'll need to get the software from the LG support website. Which model (year) are you referring to...? The latest firmware for the 2016 series (C 6 and E 6) is 5.30.30 and was released July 4, 2018. It does not resolve the (Emotiva specific) HDR banding issue from the ATV4K when the signal is passed through the XMC-1. I believe that is the banding issue Don is referring to. donh50... If that is the issue you're referring to, the last I heard from Lonnie (which was three weeks ago) is that they were finally able to replicate the problem, but have not yet found a solution. Unfortunately, my solution is to keep using my AV7703 until they do. My XMC-1 is getting pretty lonely sitting in the storage closet...

My work schedule has been insane so I've not spent much time with my system lately.

Okay... so this update is for the B6 only. The B6 uses a Realtek processor whereas the C6 and E6 both use the same proprietary LG processor. There are no firmware updates for the C/E at this time.

And I have a C7, I think... 2017 model OLED. Complete with banding. So the take-away is the latest greatest XMC-1 works great so long as I use older gear with it. Hmmm...

So I did more testing on my ATV 4k Dolby Vision. Using what I have are the AudioQuest Cinnamon HDMI cables Im still having DV issues. The DV logo pops up on top right corner for a few secs on my SONY OLED 65 A1E but the screen returns to its previous format UNLESS I select 4K DV at 30hz. however it looks very washed out! The standard 4K SD looks better. WTF! I have updated ATV software. Doesn't fix anything! My only hope is the buy those AMZ cables one of you suggested but I have my doubts. Like I said before it works perfect hooking the ATV 4k directly to the TV. Will let you all know where Im at. I would assumed Emotiva would've already released a new firmware update by now. Its been almost 6 weeks since! Come On Emotiva!

Maybe new firmware is in the works for the other LG TV models as well. A new firmware for my Samsung was released two weeks ago and while it has reduced the banding some, it still has it. I might add that I still get the banding whether going through the XMC-1 or source direct(Oppo 203/ATV4K/FireTV4K Cube or Pendant) to my Samsung.

If wilbur’s new Firmware did indeed fix his B6, then maybe LG is possibly addressing this issue with the other 2016 and 2017 models ??

For what it's worth, I was up in my bedroom watching College Game Day on a Samsung 4K 40" TV. The DirecTV client was connected to the TV with a good HDMI cable.
On a couple of shots (all were commercials), I saw a lot of banding.
My point is that it may not be the Emotiva - could be the TV or the source.

Its been almost 6 weeks since! Come On Emotiva! Apple TV4ks are not playing nice with Sony displays right now, whether you have an XMC-1 in the mix or not. I’d hold off on blaming Emotiva. My ATV4K and my Sony UHD TV work great half the time, and not at all half the time. Others are saying that, no matter what’s in the mix, their ATV4K and Sony projectors are dropping signal constantly. Others are saying Lumagens are causing the same problems with Sony projectors even without an ATV in the mix. HDMI is a clusterf, blaming Emotiva because they’re an easy target is weaksauce.

I probably missed it in all the threads, but being an analog guy dealing with things like GHz signals and not much into video standards, can someone explain the root cause of the banding?

Until there is a root-cause analysis the answer source of the problem will remain a mystery. My theory is that occasionally change causes the bit-depth to be treated improperly. In my testing, this occurs when there is a long handshake. For example, using the ATV4K watching Amazon Prime Jack Ryan, then press the long-menu press to return the ATV4K menu. When returning to Jack Ryan, there is severe banding. - Rich

The banding issue is not due to the TV or the source or cable length. I can plug my ATV4K directly into the same cable that is normally coming from the XMC-1 to the TV and it works just fine, banding-free. Im going to go back to using my XMC-1 as a non 4K capable device until Emotiva figures this out. I agree HDMI is a mess, but if the source and tv work fine together and I put the XMC1 in between, it should continue to work the same way.
My gut says this is a handshaking issue where the source is not actually sending the color depth that was negotiated.

Which in my case doesn't explain the same results whether I'm going source direct or through the XMC-1 to my TV.

Lonnie already replicated the banding in their lab. I have a Sony X930E and LG HDR monitor (no OLED) and in both I get HDR banding when the XMC-1 is in the chain. If I bypass the XMC-1 then banding is totally gone. If I use my Marantz SR6013 I get no banding either so the problem is the XMC-1, not the source.

Banding. I was able to fix banding last night with firmware updates on both the OLED55C7P and XMC-1. I was watching Star Trek UHD with my Oppo 203 and there was banding on the background sky when young Jim Kirk is on his joy ride in his hometown in Iowa as a kid. Well, I looked into upgrading FireWare on the C7 as Wilbur suggested and I went from software version 03.60.16 to software version to 05.80.04. This took several updates to get to this point because I was going thru the tv and updating from there however when I got to 04.71.00 it would not find the latest update to 05.80.04 so I had to get on the desktop on download it on a usb and do it manually. To my satisfaction that I had the latest software it did not fix the banding. I then opted to upgrade the XMC firmware from 5.2 to 5.3 and it fixed the banding in that movie. It also made the toggling between inputs snappier and there is no delay now with volume control.
