I played around my (crappy) ATT Uverse Pace 5268AC (2.4/5GHz) router yesterday and did a full reset to restore default values because I was having issues (specifically with the TV and the 5GHz network). I then used Wi-Fi Analyzer on my Shield TV to figure out the best channels to set for both radios and configured the router to always use the same channels (not set to auto). The TV literally sits 2 feet directly above the router so it can't get much closer. I'm routinely having issues where the 5GHz network is extremely latent on the TV (to the point where I can't even run a speedtest on the LG Browser or the Netflix internal app reports 1Mbit connection speed). I jump to the 2.4Ghz network and then back to the 5Ghz network and everything works fine again. No idea what's going on and I might just give up and run an ethernet cable to the TV (would rather not do this considering I actually don't have any open ethernet ports on the router and because it means running another cable up the wall). Probably TV's fault with the Wifi.

Unrelated - ran the pixel refresh for the first time last night (I think have around 100 hours on the TV now). Curious to see if I see any changes - probably won't

What's the suggest frequency to run the pixel-refresh?
Runs automatically every 2000 hours. Not recommended to run it more often unless you are having issues per Sony's owners manual advise. Not aware of any advise in the LG owners manual. Not heard of anything bad happening from using it more often, other than a very few who commented that it made their banding issues worse. Many said it made their banding better. Personally I have never seen anything odd on my set and have never run it. Have around 1700 hours on mine.

Don't need bright N pretty when it's just me alone. As long as I can see it well enough I'm good.
I use OLED Light of 37 for SDR (Technicolor Mode)...HDR/Dolby Vision I leave at the default...image retention/burn-in is definitely still an issue no matter how many people claim it's not...I had slight burn-in with my VT30 plasma

Regarding the manual pixel refresh, the consensus is to not use it unless necessary as long term use can shorten panel life. The OLED has an automatic refresh after the TV is powered off and there is 4 hours of cumulative usage.
Interesting...stupid workaround for a TV that is 2 feet away from the router and should stay connected to a super strong signal though...will check out the Internet Speed 2 (? is there a 1?) app hah

Guess I won't run the Pixel Refresh again Though I do feel like banding has started getting worse as the TV has started wearing in...wonder if this pixel refresh will help (probably not)

Thinking of getting yamaha 207 as a temporary solution until atmos soundbars come down in price or biting the bullet (doubtful) and getting something like the Bose soundtouch 300. Either way, these soundbars are 2.4 and 2.2 inches respectively. Is it a valid concern to think that these soundbars could block a portion of the screen?

Thanks for any feedback and any other advice you guys may have. Been battling what to do for sound in terms of going with stock temporarily, yamaha 207 for $299 for a while or long-term Bose 300 for $699 (ouch!). Using the soundbar for music as well (bluetooth/hooking up with Alexa).
I have the 65C7 in addition to the Bose ST300. The TV sits on its stand. The Bose does not block the screen at all. The issue I have is with the shiny glass top of the ST300. It does cause a reflection from the TV. Over time, I am now used to it and it does not bother me at all. I have read Bose sells a non-reflective film to place on top of the unit. I was interested in this option, but then again it no longer bothers me.

As far as sound is concerned, the ST300 is a beast. I listen to music as well was watch movies and stream, and to my ears nothing else beats it. I tried out all the Atmos bars including the SJ9, and the ST300 to me beat them all.

On my C7, there is an option in the sound menu that says surround. But is off and there is no way to turn it on.
I can also see it if I click on the wheel button of the remote. On the right of the screen , there is an icon for the surround sound. It is off.

Does anyone know how to turn it on
Thanks !!

This is true for BOTH HDR Picture Modes AND SDR Picture Modes.
The way I tested was to select a picture mode, set Sharpening to max (50) and then freeze the video that is playing and toggle between Edge Enhancer On and Off. It is very easy to then see the difference that Edge Enhancer is making.
Also using this method I left Egde Enhancer On and toggled between Sharpness at 10 and at 0. I couldnt see any difference at all in the two.
Very confused by LG saying it is a Bypass function so set it to On. I suppose they mean that when it is Off it bypasses your Sharpness settings, which indeed it does.
I went and tested it myself and got the same conclusions as you...turning Edge Enhancer off disables the Sharpness control in SDR, DV and HDR10...my guess is that the pdf that LG released stating that EE does not increase Sharpness and is used as a bypass function is outdated and was fixed by a later firmware update...or maybe they just translated things incorrectly...either way I've now turned on Edge Enhancer in both SDR and HDR/Dolby Vision

So your not gonna consider the C8?

I know the new pixel structure suggests the panel will be less resistant to pixel age differentiation and the new static logo feature might have stopped what happened to me but I don't want to worry about burn in any longer. If after a couple of years LG has proven it has nip BI in the bud then I'll revisit.

Glad to hear that I'm not totally mad. :
it is odd though how the blurb from LG can be so misleading and totally wrong.

do you guys also see banding like this in native Spotify app? I see it quite a lot also on Youtube materials (non 4K, but often on 1080p). Just wondering if this is something normal, or my panel is kinda "special"

I think they just worded things in a strange way...either that or it was true when the sets were first released but a later firmware fixed things

That (personally) doesn't look like banding to me (banding is usually vertical)...that looks like a super-compressed image being upscaled to 2160p which causes the ringing artifacting

Call me crazy (or its all in my head)...but I feel like the banding is less after (I believe) the run of the pixel refresh. It's also not dark so that might be part of it, but the vertical banding on my set looks less severe now. Who knows...

If that's unacceptable to you, you could put some sort of riser under the base. With sound bars that short, you wouldn't need much. (Piece of 3/4" plywood?)

Next level: a tabletop stand that uses the VESA (wall mount) points. An example that I own: https://www.amazon.com/Universal-Sta...ght+adjustment

Because of the low placement of the mounting points on the C7, mounts tend to take it high. I needed that to clear a center that's 10.5" tall.

Higher level: an actual wall mount.

Other alternative: live with the TV sound until you can afford an AVR, and discrete speakers. The C7P does some sort of limited Atmos reproduction.
This is a much better solution than ceramic tiles, which can be slippery in addition to cracking quite easily. I've used plywood in similar circumstances with great results. It's also easy to paint, if desired, but would likely be unseen due to a soundbar anyway.

Having said that, I strongly recommend a thorough research of soundbars where Atmos is concerned. In fact the entire issue of reflected Atmos, which is what is offered by soundbars, is nowhere near a simple solution. While some folks are satisfied with them, many folks are decidedly not favorably impressed.

There are owners threads for soundbars, such as the Samsung, LG, etc, here on AVS. They should be required reading for anyone looking to buy an Atmos soundbar. Not everyone agrees that the value received with an Atmos soundbar lives up to their expectations. The Nakamichi offerings have shown more versatility than the Samsung and LG models, with owners claiming more height effects than the competition.

In fact, things with Atmos soundbars being what they are, and considering what they cost, I opted out of the idea altogether. YMMV

We have the LG SJ8 soundbar - and it's sized just right. It's the same width as our 55B7P. More importantly, it has an especially thin vertical profile (just under 1 1/2" high - or 2" high with its optional feet) so that even with the optional feet, its top comes to just a hair under the bottom edge of our 55B7P, with the 55B7P on its stand. Consequently, there's no need to have to raise up the TV to prevent the soundbar from blocking the bottom of the screen (which I believe is your concern with respect to the taller soundbars you mention).

BTW, there's also an optional LG Sound Bar Bracket Stand (Model "T8") that can be used to replace the stock stand of 55" and 65" LG OLEDs by physically attaching both the TV and the SJ8 to the T8 so that it (the T8) and the SJ8 then serve as the TV's stand.)

Soundwise, we're very pleased with the SJ8. It's a huge improvement over the TV's internal speakers. 300 watts including a 170 watt powered wireless subwoofer. One caution - the SJ8 is only a 4.1 soundbar. So if you really want 5.1, 7.1 and/or ATMOS, it probably won't do - but then frankly, I doubt one really gets materially more of a true 5.1, 7.1 or ATMOS effect from just a soundbar anyhow...

In addition to using our SJ8 with the 55B7P, we use it with our Google Home Mini Smart Speaker for music - I believe one could do the same with an Amazon Alexa and the SJ8...

I have an LG OLED C7 (2017 model) I'm having a bit of a problem with Netflix.



I'm routing TV Audio, via the HDMI ARC channel (premium certified 2.0b cable), to my Denon 4200 receiver.



On most occasions the Denon immediately recognises the Dolby Digital + signal and plays Netflix audio perfectly. Life is good.



But sometimes the receiver only registers Dolby Surround and I hear a mix that includes music and effects but no dialogue. Skipping back to the start of the episode normally fixes it (Dolby Digital + snaps on) but it's really frustrating.



It happens most often when I launch Netflix for the first time each day. Going to the 2nd, 3rd, 4th show etc is normally fine.



I don't know if its a Netflix app problem, an HDMI handshake problem (I've tried 3 different cables, same result) or a receiver problem - but all three components work fine with everything else, and work fine with Netflix most of the time.



Might it even be a wi-fi / network problem? I seem to have fluctuating speeds from Sky Broadband which often results in buffering and periods of low quality video.



Has anybody else experienced the same thing?

Last night I watched Jumanji UHD 4k BD with my family..............In DV through my LG UP970.

Holy smokes........that movie looked and sounded spectacular. My wife even said, this movie looks gorgeous, better than a movie theater.

The sound through my ST300/Sub was rocking. Dialogue crisp and clean, plenty of bass and surround action.

I could not agree more with my wife. Watching movies on this C7 is better than going to a movie theater.

Tonight, we will be watching Blue Planet II. Can't wait.

I do love this TV, it is simply breathtaking.

Is your firmware updated? Netflix app updated? This was a common problem some time ago, but I thought a firmware update a few months back was supposed to have fixed it.

On most occasions the Denon immediately recognises the Dolby Digital + signal and plays Netflix audio perfectly. Life is good.



But sometimes the receiver only registers Dolby Surround and I hear a mix that includes music and effects but no dialogue. Skipping back to the start of the episode normally fixes it (Dolby Digital + snaps on) but it's really frustrating.



It happens most often when I launch Netflix for the first time each day. Going to the 2nd, 3rd, 4th show etc is normally fine.



I don't know if its a Netflix app problem, an HDMI handshake problem (I've tried 3 different cables, same result) or a receiver problem - but all three components work fine with everything else, and work fine with Netflix most of the time.



Might it even be a wi-fi / network problem? I seem to have fluctuating speeds from Sky Broadband which often results in buffering and periods of low quality video.



Has anybody else experienced the same thing?
There's no way it's a network problem. Audio takes minuscule amounts of bandwidth, especially streaming audio in Dolby Digital+. It's likely some sort of HDMI handshake issue somewhere. Unlikely the cables because again, audio doesn't take much bandwidth and if you get video then the cable is working. I have a Denon 2200w and have never experienced this problem. Have you tried using the denon remote and pressing the movie button and cycling through the sound modes? Once you do that it should remember the setting you leave it on. I set mine for Neural X and it remembers that setting every time I use the TV Audio input.

Holy smokes........that movie looked and sounded spectacular. My wife even said, this movie looks gorgeous, better than a movie theater.
Would be nice to have a 200" OLED

Just wanted to put this out there as its the first time ever seen on my set. Watching an HDR movie via the android app VLC, I paused it literally paused it for no more than 60 seconds and there was image retention with all the players buttons. Thank god it was temporary and went away once resumed movie. So now I know, HDR at least with VLC (as its the only time seen this and trust me my OCD is always looking) occurs albeit temporary within short time. Just wanted to put that out there.

Leave different apps paused all the time...I've literally NEVER seen image retention

So do I all the time without a second thought, yet this pause was with HDR active when HDR movie paused. VLC player buttons retained temporarily after 30-60 second pause and took about a minute of content playing to fade. Don't want to think what would of happened if it was a few minutes.

Can anybody please tell me what my LG C7 OLED light should be? I understand that it varies from environment but would say my lightening is average. Black out curtains with the light on. Don't really play in the dark. I have had more than 2000 hours running OLED light at default 80. Have seen image retention depending certain static icons but nothing permanent. I have just been reading burn in issues on this thread and would rather play it safe since I do game quite often. Thank you for any help!

For SDR, pick what works for you. There's no right answer. If you like the picture at 80 then that's fine.

For HDR, you need to leave it at the default settings for HDR10 and Dolby Vision.

I have blackout curtains and usually watch content in the dark, OLED light at about 15-20.
