If you are looking for good sound, or just better sound, on the street the E7 is only $150 more and you get a sound bar

First of all, Congrats on the calibration.

Have you been able to watch a DV/HDR 4k UHD movie since calibration?

Does the TV still retain the "pop" in the various modes calibrated?

Is the difference so good you would be willing to do it all over again?

I am on the fence about calibration. Your response will greatly help in determining if I proceed or not.

Any additional information you can provide would be greatly appreciated.

Thanks.
I goofed up quoting you, so please scroll for it on page 904.

Btw, my neighbor's wife said "Wow it's like Wehrenberg Theater". A movie theater chain in the mid-West.

Ok... I'm home. I'm not planning on broadcasting all my settings across all picture modes for the world to see because every set is different and it wouldn't do you much good to copy them. Not only that but there's a whole lot of RGB numbers across the color management system that were adjusted.

But... here's a couple with the basics:

ISF Expert Bright = OLED light 80 color 50 color gamut auto tint R4
ISF Expert Dark = OLED light 49 color 48 color gamut auto tint R2

I asked Chad about Technicolor vs ISF Expert mode and he said they come different from the factory but calibrate the same. That was all I needed to hear... wasn't going to question it.

I believe Mo also got ISF Expert Bright/Dark on her set.

I sacrifice the Atmos over HDMI and the Technicolor picture mode but in return I get a TV that functions normally. I have been away from the forum for a while and I just learned that the 4.70.36 rolled out a while back, so I was trying to look for peoples thoughts on the new FW update to see if go through with the update or not (i’m mainly looking to get Atmos over HDMI from my xbox one x and ps4 pro to my E7s sound bar), and I didn’t want to not make the same mistake again, updating right away without doing my research first... so here I stumble onto your post, which pretty much answered my question and I guess i’m better of sticking with my old working 3.60.09 FW.
Well dang, that's a drag. Thanks for the reply, though. Sucks to spend $1500 on a TV, mainly for HDR gaming, and the HDR be hosed.

IP control is hit and miss on the 2017's. Even for those who reportedly have it working, they have noticed some weird prompts when the TV first fires up. Also, I'm not certain that it works at all with B7's. The IP commands do not appear to be nearly as well developed as with RS232. iRule's device library includes a full featured RS232 driver with every command, and a volume level driver for use with the slider widgets. I would get a Global Cache IP2SL and add a DB9 to 3.5mm null modem cable.

EDIT: I found these instructions. Looks like you'll be getting into the service menus. Unless you know what's hiding behind that door, I would stay away. BTW, the IP commands are the same as RS232:

Finally figured out how to get the IP control dialog to appear on our new OLED65C7P (2017 US model).

First, I added the MAIN MENU command from the "LG code group 1" via IR onto a button in iRule (or you could use a programmable remote). Make sure that it is set to repeat when held.

Then hold this button down for 5sec until the channel banner appears.
Then, switch to the magic remote, then enter 828 and then the central-wheel "ok" button (this last part is important!). You should then get the IP control dialog to appear. I can then confirm that it then listens on port 9761, the power-on/off IP control does work. Note that you must enable WOL and get the MAC address for the TV (six hex pairs separated by colons). I did all my testing on the wired ethernet port, not wifi.

I did notice that powering on via IP then presented a dialog on the TV asking me whether I wanted to power on the STB, but it's working.

Much like any app, you would need to ask the developer (Hulu).

I FIGURED IT OUT!!!! The Apple TV 4k turned on ULTRA HD Deep Color and the Cable Box is not compatible!!! OMG!!! If anyone else has this problem, now you know!!!

Ok, I started a thread in the AUDIO forum but it's starting to look like it's a problem with the TV and not the receiver. Here's all that has transpired... Can ANYONE help???

I'm running an ONKYO TX-RZ710 and all of the sudden, I am getting no sound from the CBL/SAT input when I watch cable. I tried different HDMI cables, I swapped cable boxes and nothing. I connected the cable box to the AUX input and I do get sound, so it's not the box or cables. I checked the settings on the (both) boxes and they are set to output digital. When I connect something else to CBL/SAT (blu-ray) I get sound. One time I saw a quick error message flash on the screen but it went away too fast for me to see what it said. When the cable box is connected the front display does not say HDMI, but when I connect the blu-ray it does. Is there a setting I'm missing? Did my 2 year old daughter press a button on the remote??? HELP!!!

I called Onkyo and did some troubleshooting and we are both perplexed. Here is what was done...

Full reset to factory settings.
Swapped cable boxes.
Disconnected all devices except the one we are testing
Cable Box in CBL/SAT = Picture but NO SOUND
Cable Box in BD/DVD = Picture and sound
Blu-ray Player in CBL/SAT = Picture and sound
Blu-ray Player in BD/DVD = Picture and sound
Cable Box in PC = Picture and sound

Multiple HDMI cables used with the same result.

So the ONLY combination that doesn't work is Cable Box in CBL/SAT, which only stopped working 4 days ago and had been working for 7 months. The only thing that changed in all that time is I added APPLE TV to the receiver but in a different input.

NEW UPDATE:

I connected the Box directly to HDMI 2 on the TV and got picture but NO SOUND!!!! Then I tried a different box and got the same result. Then I moved it to HDMI 1 and I got picture and sound from the box directly to the TV AND from the receiver on CBL/SAT!!! So, it seems to be when the TV is getting a signal into INPUT 2 that is identified AS Cable? When the receiver says it's something else (BD/AUX/GAME) the TV and Receiver pass the sound. So, I have to think the receiver is NOT the culprit and it's either the TV or the Cable. But, since the issue persists no matter what box I use (I tried a third box) I'm leaning more toward the TV and possible ARC causing issues.

true but I thought since the base Hulu app was available that it would be easy to add the Live TV app...much like YouTube Live TV was added in later (while the standard YouTube app was available from the beginning)

It could be an easy add, but the motivation/user base may not be there. It also depends on how many resources are dedicated to WebOS. LG is just the “home” of the app so to speak, they wouldn’t have anything to do with adding/removing features.

I really do not understand the "too dim" with HDR Game Mode. My C7 looks great in Game Mode. Playing God Of War, Horizon Zero Dawn, Sea Of Theives, Gears Of War 4, Madden 18 all look Amazing! I know Standard picture mode is brighter but Game mode looks better in my personal opinion. The C8 has tone mapping that is suppose to help for those that find it dim.. but Rtings said that they do Not recommend Dynamic Tone Mapping since it changes the Picture curve too much.

Thank you for posting this.

I'm not interested in your settings. I do calibration myself. I was just wondering if the tint trick for skin tones is still valid for Chad.

Actually no. HDR is Technicolor Expert as is HD Dark (Light Control). Dolby Vision is Cinema User

Has anyone had an issue where the their LG 7-series will just suddenly stop outputting the center audio channel when playing content with multi-channel tracks?

I've had this issue happen to me twice now and I don't know what causes it but leaving the TV off for a while resolves the issue. This is super annoying as it's difficult to create a reproducible test scenario which I could explain to a technician so I was hoping maybe it's more common and somebody has some concrete info on this?

This affects all application on the TV (e.g. Netflix, Amazon Prime Video, Plex) and causes all center audio to disappear while the other audio channels are fine which results in all the dialogue going missing and only hearing ambient sounds and background music, etc. There is no change whether I send audio through to my receive or directly from the TV and outputting the stereo track is the only instant work-around (I have tried everything except doing a full factory reset, which would be a major pain). The only fix so far is just waiting a few hours.

The only thing I can think that might cause this a defective audio chip somewhere in the TV that may stop working properly if it gets used too much (or extended use at a certain temperature) as the TV was used a lot this weekend.

It’s still amazes me that in 2018 RS232 quite often still offers a more solid connection than IP. I still run a few of my devices that way because their IP implementation is flaky.

Hey guys, gaming is great on my C7 but while playing HDR games does anybody notice the ABL? (Automatic Brightness Limiter) Depending on the scene in the game the brightness tends to fluctuate.. I believe it's the nature of OLED but just curious if you guys are seeing the same thing?? Notice it happens in SDR games as well like Fortnite. Thanks.

On other pictures modes like vivid or game is the function is available to be turned off

I have had this happen twice on my G7. I chalked it up to the internal apps (both times it was Netflix) and the system needing a reboot (not unlike when apps get flaky on your PC, phone, etc...) - unplugging the TV for a min fixed it both times. I do not think it is hardware related.

Nice... hope it helped.

Very pleased with Chad's calibration. SDR looks much better... and HDR/DV look stunning. Same can be said for the first 1080p BD I looked at... "A Dog's Purpose." If I didn't know I was looking at 1080p I'd have said it was 4K all day long.

Fix for Center Channel Dropout

I've had this issue happen to me twice now and I don't know what causes it but leaving the TV off for a while resolves the issue. This is super annoying as it's difficult to create a reproducible test scenario which I could explain to a technician so I was hoping maybe it's more common and somebody has some concrete info on this?

This affects all application on the TV (e.g. Netflix, Amazon Prime Video, Plex) and causes all center audio to disappear while the other audio channels are fine which results in all the dialogue going missing and only hearing ambient sounds and background music, etc. There is no change whether I send audio through to my receive or directly from the TV and outputting the stereo track is the only instant work-around (I have tried everything except doing a full factory reset, which would be a major pain). The only fix so far is just waiting a few hours.

The only thing I can think that might cause this a defective audio chip somewhere in the TV that may stop working properly if it gets used too much (or extended use at a certain temperature) as the TV was used a lot this weekend.
I've had this problem a couple of different times. Spoke to LG about it.

It is caused by an upgrade either to the TV firmware or to the LG software or APPS.

Simple fix:

Pause your program turn TV off then back on. Center channel should be back.

LG Fix:
Reboot TV---

Use power on/off switch located lower back left side (E7) and turn TV off.

Remove all HDMI cables from TV.

Turn TV back on from power switch holding switch in on position for 10 seconds.

Let TV fully come on.

Turn TV off with remote (or power switch)

Re-attach all HDMI cables.

Turn TV on usual manner.


That should work until the next significant firmware/software upgrade.

That’s...odd. I’m not sure why that would be. Maybe someone else can chime in here.

And if you read the entire thread you linked for me, you'll see that the 2017 OLED's (but not the 2016's) can indeed pass DD+ w/Atmos over ARC, provided the audio equipment supports it. However, much available audio equipment does not recognize Atmos on its ARC input even if it supports Atmos for its other HDMI inputs. The most common working pairing I've seen is (perhaps unsurprisingly) the LG SJ9 soundbar. I've also seen a couple reports of it working with receivers, but not very many. Whatever needs to be done to allow DD+ w/Atmos over ARC seems to push into a gray area of the ARC specification.
I have an entry level Onkyo TX-RZ610 that does Atmos just fine.

You have an RZ. They have a dedicated support number. I had a sound issue and they walked me through a front panel button combo that fixed it. RZ support is great.

Not really. I only notice it dim down when I have it paused or something for a while. While playing I do not see any noticeable changes to brightness.
