It?s rwally disappointing how they have abandoned their first mass oled models in the 2016 6 series. We spent all the money and got LG popular but they haven?t given us any updates that 2017/s get.

I?m not sure all of them are hardware related reasons either.

It's buffering and then catching up and then buffering again. It auto adjusts the picture quality so that it at least keeps playing. It probably has nothing to do with your bandwidth. Most likely caused by the servers the data feed is coming from.

We've just finished watching all episodes of The Marvelous Mrs Maisel (recommended) in 4K HDR. It always starts out fuzzy and ramps up to full resolution in about 40 seconds. We haven't seen it go back and forth though. Ours is a wired connection at 100+ mbps.

Did you get the SJ9 or something else?
Yes, I got the SJ9 and B7. It sounds fantastic. Also, BB has a promotion right now that knocks $300 off the sound bar when u bundle with the tv purchase. Or at least they did a week ago.

That's Amazon for you. Everything starts that way and then ramps up like you said. I bought a kids movie last night and it started out in what looked like 240 and went to 1080p. Grand Tour does it as well. Netflix for some reason does it right

Hmmm. I noticed that I had better results using the sling app on my firestick the other day instead of the lg built in sling app. Maybe I'll try the firestick for Amazon and see if I get better results.

Maybe I'll try connecting the TV to the router. I'm using wireless right now. 4k man in the HIGH castle looked solid throughout but I had problems with HBO's the Newsroom.

Wired > wireless. Always.

No streaming will require 100+ mbps so 10/100 is irrelevant. Since you are going straight from your router you don’t need to worry about your internal house wiring.

If the issue isn't insufficient bandwidth/interference but instead the time it takes adaptive buffering to get up to speed from various streaming services/devices then connecting to the router directly shouldn't make much of a difference.

You know how that works. Well see it when we see it, hopefully they would do that Hopefully only firmware is needed, and no hardware as that would put a wrench in that plan.

PS4/ARC question, just to understand what's going on...

I have a Nakamichi soundbar system with discrete rears. It accepts up to 5.1 PCM/DD/DTS. My PS4 Pro is connected to the C7 with ARC back to the bar. The C7's ARC format is set to Auto. It works fine, I just don't understand quite why. The PS4 can output audio in PCM, DTS, or DD (encoding the latter two on the fly). If I choose DTS or DD, the soundbar blinks the appropriate LED's indicating those formats. Expected. If I set the PS4 to PCM, no LED's blink, which is what happens when the bar gets PCM input. What's surprising is I'm still getting rear channel sound. But 5.1 PCM can't go through ARC, right? So why am I getting rear output? I'd have expected the C7 to either take the 5.1 PCM from the PS4 and transcode it to DD 5.1, or else to downmix the 5.1 PCM to Stereo PCM. But neither seems to be the case.

Although LG didn't say much about processor differences between the '16's and '17's when the 17's were announced, there must be something hardware about the '17's that enables support for the newer HDR formats, and also provides for better motion handling with the 17's as well. Certainly the panels are different enough ( 3D vs. 2D ). Apparently you need a better processor in order to handle Web OS 3.5 that runs on the '17's. For 2018, LG is touting their new A9 processor, and all the additional improvements in motion handling and processing with true 240Hz panels. I think they may finally have an answer to Sony's venerable X1 family of processors.

Below is a link to an extensive comparison between the '16 and '17 C's. This was done back in April '17, so the hardware differences were already apparent. To quote: "Meanwhile, not only HDR 10 and Dolby Vision format that supported by LG OLED C7, but it also already supports other HDR formats including Advanced HDR by Technicolor and HLG by BBC and NHK."

It looks like there is some English language challenges or translation issues but you should get the gist: http://www.4ktvcomparison.com/lg-ole...-vs-oled65c6p/

IMO, it's hardware related, and has been the case since the '17's came out.

Nothing much to really talk about until LG states something. It’s a bit early in the process to have any real discussion as the “fix” needs to be integrated into a firmware and tested.

The '17s were destined for this update all along. I just found out that LG announced this capability when they introduced the 2017 models last year. Probably the last hurrah for the '17's though.

Hey guys, can you guys recommend me a thin (not full motion) wall mount to compliment the C7's thinness? I'm looking for the thinnest (while remaining reliable) wall mount. This is my first TV mounting exp. ever.

Kind regards,

Max

Soundbars are nice but after having what some call “the best” Sony HT-ST5000 for a month, I just can’t get over how hollow they and my previous soundbar sound compared to an amp and just a pair of towers which I just set up today. Quality stereo sounds infinitely better than 7.1.2 “surround sound”. If you can fit real speakers and an AVR go that route instead.

The B or C is definitely the right choice though.

The SJ9 is $600 when bought with a TV and the C7 is $150 more than the B7. So I guess the best way to word my question would be is the SJ9+B7 really a $450 upgrade over just getting the C7. I’d love to have a surround setup, but I live in an apartment, and surround won’t be feasible until I graduate school and buy something permanent.

I have a wired connection. Test speed with fast.com using internal browser gives me ~50mbps (what I pay for). Internal Amazon app takes a while to ramp up to 4k, too. Don't know if Amazon is to blame or the app.

When has a lack of information stopped anyone from talking about it! LOL And in this case, there's confirmed info form the manufacturer, and their admission of fault...just surprised someone hasn't started a campaign to inundate LG with questions as to when they'd incorporate it.

If you don’t care about input lag and hate the dimmer picture in game picture preset, what’s the next best picture preset for gaming? Is it Dark Room or Bright Room or Standard, or Technicolor or what? I set up Standard and really appreciate the brighter image. Also, I tried the PC Mode input trick and noticed it’s even cleaner, although I can see that HDR looks more subtle than with PC Mode off

Btw any downside to using PC Input mode for gaming on the Xbox One X on the LG B7A? I noticed that on PC input mode I can switch to HDR Standard preset (instead of game mode) and the input lag stays low because it’s in PC input mode. Should I avoid this? I’m trying to find more info on this.

I have the EG9100 with the silver bezel and the C7 with the black aluminum trim around the bezel and I'm fine with either one. What makes the C7 worth the $150 premium for me is the aluminum metal stand instead of the plastic stand of the B7, of course if you're a wall mounter then that's a moot point.

Interesting or perhaps not so interesting is the B8 has a stand similar to that of the C7 but in black while the C8 has a stand that looks a bit weird in my view that's also in black. Both models IMO continue to have an overall elegant design.

This is what I would expect with adaptive streaming regardless if you have a wired or wireless connection so if one's only issue is waiting for the picture to ramp up to 4K then I wouldn't make plans to drill holes in your walls or floors to get a wired connection thinking you'll no longer have this issue.

What's surprising is I'm still getting rear channel sound. But 5.1 PCM can't go through ARC, right? So why am I getting rear output? I'd have expected the C7 to either take the 5.1 PCM from the PS4 and transcode it to DD 5.1, or else to downmix the 5.1 PCM to Stereo PCM. But neither seems to be the case.
ARC can pass a 5.1 PCM as you system is demonstrating to you. I do not believe the C7 will do transcoding of PCM 5.1 to DD 5.1 if the setting is at Auto, but it will transcode any input to PCM if the output is set to PCM.

I’m finally really happy with the picture quality and input lag on LG B7A and Xbox One X. The settings that worked for me are first enabling PC input mode on B7 and enabling PC RGB color space on Xbox One X. The results are incredible. The best part is that since you’re using PC input mode, you can still toggle to other picture presets outside of Game mode and your lag will be excellent at 21ms thx to being in PC Input mode. Here are some screens taken with my iPhone X that show how it looks on:

Looks incredible. I am using the isf Expert Bright Room setting for SDR content. Checked the Xbox one calibration app and I see all the right squares so it’s not clipping whites or blacks. On HDR I am using the HDR Standard preset and it’s not dim like game mode and still has 21ms of input lag. Best of both worlds! Finally happy!

I am pretty sure ARC is limited to stereo PCM due to bandwidth limits (it was only designed for about 1Mbps and stereo 44.1Khz 16bit is already 1.4Mbps).

That was always my understanding too, but 5.1 PCM ARC would explain what I'm seeing. I don't think the soundbar has any kind of special upmixing mode. Did I totally miss a memo about 5.1 ARC PCM somewhere? Is this some special capability that only some sets and/or soundbars have? Come to think of it, I remember a comment from a Nakamichi rep in an email reply that implied such a capability. I thought he just misspoke or was clueless and didn't follow it up.

If that really is what's happening, I wish I had known before. It would have saved me a ton of screwing around with various bitstreaming options.
