Just wanted to post a quick update from my LG UB9800 nightmare last November. So, the 3D was unwatchable unless I was 18-20 feet from the TV...and then only letterbox movies were ok, full screen ALWAYS had top ghosting I couldn't live with. So I exchanged for Samsung UN75HU8550. Sammy had better picture imo, but even Active 3D had ghosting (though not as consistent an area as ub9800. By this point I was tired of wasting so much time & $$$ on a tv I had to settle for, so I sold the Sammy on Ebay. Lost about $1,600 between LG restocking fee & Ebay losses, but now I have my 82" DLP back & awesome as ever...& I got a 70" Vizio passive 3D from wal mart with 3 year warranty & near perfect 3D. So in the long run, I still came out ok with 2 tvs, $2,500 less spent, & a lesson learned that 4K tvs aren't for me. ..I just expect way more from 3D than they deliver. & honestly, the fake looking picture really took away from viewing also. Sure, maybe I could've gotten a smaller 79ub9800, wall mounted it for better distance/angle control improving 3D a bit, but I like sitting 7ft from my 82" & never having to move my tv or couch (shouldn't have to rearrange living room if I'm paying that much for a tv😀)

All in all, LG "VIP care" treated me horribly, didn't even offer a smaller tv exchange, & basically said it was my fault that I couldn't move my couch at least 22 ft from the tv...even though that's never mentioned in the manual. I will NEVER buy an LG anything as long as I live. Here's hoping they don't gain a smart tv monopoly in the future...
Oh, I know my 70" vizio panel is probably LG & though it sucks, at least VIZIO tech works better with the 3D at 1080p & I have a 3 yr warranty.

The LG tech support is pretty bad, you just have to try again until you get someone sensible. You obviously had a malfunctioning set as the 3D on mine and most others is pretty flawless, much better than any Active set I have seen and certainly than the Vizio.

As for that monopoly, well LG is the only one producing OLED panels still so will have a couple of years up on all the others who will come out with their 1st gen sets probably next year while LG will be on their 3rd or 4th gen. So you can hate them forever but really I've found service from many other companies isn't much better. In my experience, LG stuck to their promises and upgraded my flagship model 1st gen 4K set to webOS, HDMI 2.0 , HDCP 2.2, etc. Not many other companies would have done that...so even though they have their flaws an LG OLED is almost certainly my next TV...

Enjoy your Vizio.

I thought it was a bad panel also. They sent a specialist out who diagnoses & even works on tvs at house calls. He could've switched out any boards on the spot. He physically saw that the closer you get, the worse it was...& vice versa, further=better. I really think most people just arent as nit-picky as I am & can handle some ghosting. Because i will say many scenes WERE perfect, especially with letterbox & 18 ft back. the tech agreed with VIP & said i needed to be over 20 ft back. Thats unacceptable, in that case, no diff between 1080p & 4k.

Hoping by 2020 oled will be much cheaper😊

Yeah man that sounds like a horrible experience all around and not the way any customer should be treated. Considering most of us will buy many tv's in the future they could have earned a life long lg customer if they had replaced your set from the beginning. I too am EXTREMELY picky when it comes to picture quality and my set is flawless from 8 to 9 feet away even when watching 3D so I too think you got a bad set.

LG replaced the processing unit and power supply and the intermittent black screen problem is fixed <whew>. I was worried that it might be a limitation of the 79" 4K similar to the 84" 4K stuttering problem I had a year ago when they took it back and gave me my money back (which I promptly spent on their new 79" unit as soon as it became available ;)

I emailed LG about this. Looks like you need to change the setting in the service menu for dolby digital to pass. If this is in fact true. Why in the world would it be disabled from the factory in the service menu? Either way. Here was their response. I will also say this. Its no placebo effect either. Using ARC. It does not sound good with the soundbar. It even says its sending PCM 2.0. But when hooking up directly to the sound bar and setting my devices to dolby digital. Directv dvr genie and PS4 for example. It sounds much better and it says DD 2.1 Directv box is using optical and PS4 hdmi. I tried getting LG sound sync to work. But, the wireless sound would cut out here and there every so often. The soundbar we got today is the LG NB5541. It replaced our Samsung HW-H550.

Put that one in the bedroom. Getting a bit off topic here but man. This LG soundbar completely stinks. The Samsung kicks the crap out of it. The LG is no where near worth the $599 asking price LG wants. I got it for $249 new. But I feel its not even worth that. Samsung also has the better build quality soundbar wise. The LG feels super cheap. The sub is built like a tank though.


Thank you for contacting LG Electronics. I am delighted to hear from you as our valued customer.

Please accept our sincerest apology for any trouble or inconvenience we may have caused you. We sincerely regret that you have experienced difficulties with your LG product.

Most LG units output PCM audio by default, meaning they do not support 5.1 Channel Pass Thru. However, some LG models have the option to change the Digital Audio Output format.

Let’s try some troubleshooting steps.

First, let’s check digital audio out option;

If the device has the option to change the Digital Audio Output, It will be located by accessing the following:

1. Home or Menu
2. Setup or Settings
3. Audio
4. Digital Audio Out
i. Select PCM if connecting to a stereo system without 5.1 Channel capabilities.
ii. Select AC3 if connecting to a stereo system with 5.1 Channel capabilities.

If the device does not have the option to change the audio format, please try to Bypass TV.

Connect the optical cable directly to the home theater system from the output device, bypassing the TV all together. Some Home Theater systems have HDMI inputs/outputs as well. The TV must support Audio Return Channel (ARC) to use the HDMI as an audio output. ARC must also be enabled on the TV using the Audio menu. This may be an option if you not have an optical cable.

We can also send a technician to your home to change the audio settings from PCM to AC3 in the service menu. This will allow the TV to pass Dolby Digital 5.1 Channel audio to the audio system.

Note: DTS Audio is not currently supported on any LG Television.


I hope this information has been helpful in addressing your concern. Should you have any other questions, please feel free to contact us again via Email, Live Chat, or Phone by calling 800-243-0000. You will also see a short survey at the bottom of this email to rate your experience today which will help us know how we’re doing in providing our valued customers excellent service.

Thank you for choosing LG and have a wonderful day!


Sincerely,

Lord Skyler

Just an update. I followed through with LG allowing the tv to pass Dolby Digital. Not just PCM. It can be done on all 4k LG tv's. It is simply disabled from the factory in the service menu for LG does not have to pay Dolby Digital licensing fees. That is my guess. Or people simply do not care enough and LG leaves it disabled because of that. I am using HDMI ARC with my LG soundbar as well. Picture attached for proof. My soundbar also confirms Dolby Digital is being used. So, everyone saying these tv's are just limited to PCM and will only pass that. Using HDMI or Optical. It is completely false and needs to be addressed in the service menu. LG will do this for you for free as long as the tv is under warranty. The tech just left the house a few minutes ago.

I also wanted to add. Since the tech. here had direct access to LG techs. These guys even have access to the actual television models while working on the phone with them as they go. I asked if a firmware update would revert the previous settings back. He said absolutely not and they stick when making changes like that in the service menu. I would also suggest not doing something like this yourself. One false move in the service menu and you will have a big expensive brick. Call LG instead and they will be happy to get this set up for you and have someone come out.

Just saw this in a review of the TV...

"When I play a widescreen blu-ray on an LG player, there are black bars at top and bottom using 16:9 aspect ratio."

:confused:

I am still trying to understand why some people are having 3D problem with these sets, while others have no issues. I have watched a bunch of 3D stuff now, sometimes with several other people - all of it perfect with no complaints from anyone. Why would the same TV, supposedly with the same parts from the same manufacturer, be so inconsistent?

With the previous generation 84" (purchased Jan 2014, but I think it was manufactured in 2012 and was their 1st Gen 4K) about one in five recorded media played back from network server via WDTV would stutter about once/second. Wasn't file type / encoder / codec dependent. Happened on AVI, MP4 and MKV. Was able to replicate playing straight from USB stick. Bought from American TV, but they went out of business, so had to deal directly with LG VIP Tech Support. They tried replacing processing unit but that didn't fix the problem. They tried replacing the entire TV but the installer broke the TV. Then they bought the TV back from me for the original price. VERY nice of them to do so!

I have a feeling that the later semi-version of the 84" that had a slightly different back port panel (can't remember right now what the model #s were) and I believe also had an upgraded processing unit would have done the trick. Regardless, the new 79" doesn't have that problem so I'm happy as a clam!

Hello everyone. Quick question regarding the 79" which may apply to all, not sure. Hopefully I am asking this correctly, apologies if it isn't clear (no my intent).

Is there anything we need to set within the TV settings to prevent audio delay or sync issues?

So far it appears to only happen when I am streaming movies from our dedicated plex server. I don't believe it is a throughput or resource issue nor network. We have used this plex / htc server for some time now which is made up of a 8 GB / i7 Linux server that mounts the content off a ReadyNAS array.

Everything is pretty much the same and we have only noticed this recently on the LG. I've not seen the issue while watching movies on our Sony TV. Main difference, if any, is that the Sony is accessing the plex server via the PS4 which has a native app. Within the LG we are accessing it via the web browser.

I have searched the thread a bit but the only audio / sync issues appear to be related to 3-D. I see there is a plex app for the TV so I'll see how much it is later and give it a try maybe. I don't recall what the movie was I was watching from the plex server but I'll make a note just in case it is something related to the resolution. I'm wondering if it is a issue of DvD vs. Blu ray and the LG scaling? But then again I'm thinking if I am accessing the plex server on the LG from the web browser the plex / Linux server would be handling the transcoding so that theory may be a bust :)

Thanks for any info. I'll continue to read and search :)

I've run into the lip-sync issue with my 84" on some 2D Dish Network content as well as 3D Blu-ray. All of my components run through an avr (pioneer sc57 which isn't a 4k avr if that matters). The lip-sync problem is pretty speratic as it doesn't occur much but when it does it's WAY off...a good 1/2 second or possibly more id guess. Using 10 and 18gb hdmi cables and CAT7 for streaming so I don't believe the sync issues are caused by any of the connections.

I'm currently using HDMI 1 as my main input although HDMI 2 would likely remedy the problem when it occurs. Between work and kids I haven't had much time to play with HDMI 2 (ARC) yet although playing with the audio delay on my avr does fix the issue.

Are many of you using hdmi 2 as your main input to prevent lip sync when running all components through an avr? I've been using hdmi 1 for the hdcp 2.2 compliance with Netflix 4k although i dont believe that even matters given my avr doesn't have 4k pass through (although Netflix House of Cards looks 4k playing via the ps4 app then into the avr and out to the LG). The LG upscaler must be working wonders bc 4k netflix content looks amazing even playing through the PS4 app!

Speaking of inputs I tried using HDMI 3 as my main input but kept getting a pop up from the tv when watching satellite bc my Dish Hopper isnt compatible with the deep color 4k setting the tv can generate. If some of you use HDMI 3 as your main input when running through an avr have you just been disabling deep color on the LG until you're going to watch a Blu-ray? If so do you notice a difference between the deep color 10 bit of HDMI 3 compared to the other inputs?

I have my PS3 and PS4 set to automatically accept deep color when available. I really just need to fiddle with things a bit more but wondering how you guys have yours setup?

Thanks for the information DC7.

I forgot to mention that we are using HDMI port 1 for the cable box. HDMI port 2 is used for the PS 3/4. We do not have a AVR yet although I that raises another question for later I would wager. I recently narrowed down the AVR choice to the Yamaha 2040 and wondering if you connect all HDMI devices to the AVR first then route a single HDMI from the AVR to the LG/TV. Probably more of a convenience or quality of the upscale I guess.

I wasn't aware that the LG HDMI ports did or support different things. I guess I need to check the docs again.
