As I said, the CMS doesn't have the range. What appears to happen is that Wide Gamut extends the gamut out along the Rec.709 hue lines, not along Rec.2020 which is what is needed for UHD.

This was a question on when/how often it 'needs' to be done, not when it is able to be done.

Is it something that needs to be run regularly?

From what I am seeing is yes it needs to be done. I seem to get 6-8 hours of viewing before I start to see the minor banding that is barely noticeable to begin with. Setting it to run overnight seems to mitigate the panel noise. Make sense?

Problem has been solved. The issue was with the Tivo not with that LG.

Still chasing handshake issues. I'm trying to see if the sequence I turn the components on makes a difference. My chain is Roku or Oppo to Denon to LG. What I have seen is that the handshake process takes 15 or so seconds, if not a little longer. I watched a BluRay and got the Resume or press stop to go to the beginning from the player, lost the signal, got the do you want to go to the input screen on the LG and if I was just patient, I first got sound and then video. My normal reaction would be to turn something off and then back on.

Logically, if I get the same white border with the your tv is not 2.2 complaint regardless if the source is Roku or BluRay then what generates the message? If the LG wouldn't it just say 'no input'? I'm thinking the handshake refusal is on the Denon side just because the message takes the same form.

Plug and play is a lie.

Thats interesting. Why is that technically speaking that after some hours the banding gets stronger and then after the software works it magic weaker? Also I'd be interested in the changes to the better or worse over time (weeks, months) if these "6-8 hours" become 10 or 5 hours Or maybe it doesnt get better or worse over time?!

Thank you for clarifying.

Wow, have to say that's a bit disappointing that you need to run it that often to alleviate any panel noise. That especially can become a problem on days where I may do a marathon of some sort and 6-8 hours could be viable (however this is pretty rare). Although I guess it's better than not being able to resolve the issues at all.

How long does it normally take to run the compensation cycle again?

1 hour. But keep in mind I am watching hockey which is a banding torture test lol. I assume with regular content that duration would be much longer without distraction. Also keep in mind the 9500 did a compensation cycle after 2-3 hours of watching. No different here except you can manually do one if needed.

Ok, so what would you consider as 'regular' content? I would have considered ice hockey as normal content. But my definition of normal content is anything you could watch on broadcast, blu-ray or even games. Something not normal would be like looking at the different percentages of slides.

I was meaning banding will show up more often with a fast panning scene such as hockey. Couple that with a relatively solid background and it will be easier to see then a show or movie with not as much motion.

I'm going to put my money down on an E6 I think. I've wanted OLED for a few years since plasma died, and I think they should be showing up the week of April 11th. I'm going to pay the extra $$$ over the EF9500 as I want the better input lag and Dolby Vision support. I just hope the brightness measures as good as the G6 as well as the input lag and of course better panel uniformity.

Hey buzz, not sure if you are primarily in Wisconsin area or your Florida location, but I should be getting a g6 in the Milwaukee area sometime this week or next if you personally wanted to put your meter to it. Otherwise as stated before, I'll try and run a variety of tests with my c6 and post when I can

Well interesting thing I noticed about the clear panel noise. Yes, you can schedule it when the tv is off, but it's a one time run and in order to do it again you have to go into settings and schedule it again. Would be nice to be able to schedule it on a regular basis. What I don't know is if the tv is doing anything like the 9500 is after a period of time.

I'm in Wausau and would love to check out your G6 but it's a little too far away. The C6 will do a good job so have fun with the new OLED and please post your findings. You'll be one of the first to see what the 2016 LG's are really doing.

Is that another way of saying "it ain't gonna work" for UHD? I guess this will be an interesting topic to discuss when I get my TV calibrated (soon).

The built in OLED profiles are no good on id3/colormunki display/c6. Raw mode is pretty close, but even better, Sillysally created a spectral sample for ef9500 for us with his JETI, which you can download here:

There's a chance its no good with the new 6 series OLED but definitely worth a try.

So what, if any Dolby Vision content can be seen on this tv? People in the Vizio P series thread are posting some incredible pictures of DV content. Haven't seen any on here...

I found this thread very illuminating re: uhd calibration - https://www.avsforum.com/forum/150-bl...tion-disk.html

Which begs the question, why bother even using WCG with HDR on the 9500?

Here's what Wide Gamut does relative to Rec.709





and relative to Rec.2020





So this is what the EF does, and can't do...... (too late to correct misspelling "approximate")

There's an update available now for the Amazon app. I just installed it and it fixed the problem.

Thanks LG. Or maybe Amazon fixed it.

TV's were close to hitting P3. So they pretty much abandoned the upgrade to P3, and went with rec2020, but then made everything P3 inside of rec2020, because rec2020 is ridiculously unachievable anytime soon in a consumer tv. Does that sum it up?

Please let me know how you updated the app? When I click on my app Amazon there is no option to update..
Also, please keep checking as when I updated my app last it worked a few times and then stopped working again...

Kingsman was shot in 2.8k

By the way sony isn't the only one using 4k DIs, lionsgate has 3 so far and fox has 1 (mazerunner) and #2 will be the revenant.


These artifacts you're seeing I believe are also there on the blu ray of you're talking about what I think you're talking about. They are just more apparent on the 4k version because it's brighter so it's easy to see, and when upscaling it can bring those little things out.

I Read mporter's post and went to the LG Amazon app and it said update available. I would keep checking, maybe they roll them out.

I got a general app updates notice that appeared when I was on the home screen. Then I went to the Amazon app and the update was available.

They probably do roll them out to control the number of update requests at the same time. Also, if you do a small number first you can verify the process is working ok.

My Amazon app got updated a few days ago in the same manner - I think another member reported his updating also - unfortunately that did not solve the problem...

Unless you have a new update after the one I received .... I hope that is the case as I really want the Amazon app to work.

OK - good news - the Amazon App works...
I figured a way to find the upgrade for the app (or any other app for that matter) - go to the LG Connect app and choose Premium content and under that you find vudu - Amzon etc - when you click on for example Amazon it will take you to a screen where you will have the status of the app and whether a upgrade is available...

Now if LG can:

1. Get VUDU UHD app working.
2. ON Netflix DV content (I think only Marco Polo is DV as of yet) the picture freezes over and over again... needs a fix.

That gamut coverage measurement is not a volume measurement?

I just went and tried playing Marco Polo with the Netflix app. Played fine for 20 minutes without any freezes and, when it started, showed a message about playing in DV.

There might be something else in your set up which is causing the freezes.
