That's what I was assuming it meant.
Though I hadn't realised they used a common firmware image. Maybe just the B8s since they have the same chipset as the 7 series?

The B8 had this update on 3/12 SW File(Version 04.10.20)



1. Improvement
1) To improve that the subtitle is not displayed when HbbTV app in on. (except US Model)
2) Change HDR luminance curve. (webOS4.0 O18 Model)


The C8 also had exactly the same so who knows!

If the luminance curve is changed the basic foundation is changed.

When I did a search on the UK site for their version of the C7, 05.80.10 also shows as available for that model. So it looks like both the 7 and 8 series will get this update. The change log is the same, and still specifically lists #2 as an 8 series patch. So, it don't think it will have any effect on the 7 series models, and therefore any HDR specific calibrations.

Where you able to also actually test it on your 2017 model?

No. Not even going to try as I don't believe it is compatible with U.S. models. I'm going to wait until something pops up on the Korean or U.S. site.

EDIT: Which is still 5.80.04

Has anyone seen similar behavior?

Disabling CEC power controls on the TV "fixes" this, but now I can't turn the TV on and off from the Apple TV remote.
I just upgraded last night as well and ran into this same issue. I saw your post but thought you just got unlucky as I know many have had CEC issues and my setups been relatively without issues. NOPE, got the same issue. Spent a while troubleshooting and finally figured out how to fix it. Turn off "Quick Start +" in the options menu and it'll stop turning back on and you can still use all the CEC functions from your apple remote to control the TV. Doesn't seem like quick start + makes it start up any faster so no harm really having it off and might save more energy. Also I usually have to wait about 30 seconds for my receiver to pick up the ARC signal anyway so I'm used to waiting before starting to watch.

Hope that works for you as well, best of luck.

My setup: Sonus Faber Venere 2.5 and center, Ascend HTM200SE surround, NHT atmos minis, dual Rythmik L12's, Pioneer SC-95, Minidsp DDRC-88BM, Rotel RMB1077, LG OLED B7P

Just picked up a B7, gorgeous picture, glad I tried it out instead of just sticking with the Vizio PQ, even though that's a great set as well.

Some questions about OLED light level for the native youtube app, should I leave it on 100 like it's recommended for HDR 10 sources?

I've read for HDR 10, OLED light should be 100 and for Dolby Vision, it should be 50.

I've also read we should put sharpness at 10 for these LG sets, as that is the true neutral setting. Does this also apply when the option comes up to adjust H and V sharpness separately?

Thanks for any advice, much appreciated.

LAST LG 2017 OLEDs + X1X/webOS CALIBRATION EDIT:

  • V4 / (non-PC) HDR Game Mode was finally fixed by LG starting with Official Firmware 5.80.10, and is now the recommended method for X1X HDR Calibration
  • SDR/HDR Color Temperature is back to W50 in order to get as close as possible to calibrated HDR Technicolor Expert colors
  • Recommended HDR Luminance in games' slider (if available) is now 4.000 nits
  • SDR webOS Gamma is now BT.1886 ("GAMMA1" or "HIGH1" for SDR Game)

I don't recall seeing this version number mentioned anywhere else, even as a beta.

Apparently it *doesn't* resolve the 2160p50 bt.2020 colour problems that came with 5.80.04.
Was about to ask the same question what it does. popped up on my screen yesterday

Wasn't the luminescence change only on the 2018 models? I read HDR game mode is still dark on 5.80.10 on the 7 series.

When using the suggested settings for both, switching between HDR Game and HDR Technicolor Expert + Active HDR is now virtually identical.
This is the first time it happens with my tests, especially reproducing 4K/HDR Blu-Rays and playing 4.000 nits games so, yes, it's fixed also for 2017 models.

Awesome, I'll have to wait for the American or Korean version to try it out. Sounds like the change should carry over to the standard Cinema/technicolor modes as well and dynamic contrast low won't be necessary to get brightness back on content that was mastered at a high nit level...

Whats the latest firmware of 2017 LG OLEDS? When I search for updates it says there is none... however I think my tv is far behind...


Also what's the best setting to tweak when watching sports on basic cable? (Xfinity/Comcast) for all the motion? Watching hockey whenever you see the players skating its soooo blurry for lack of better words, same can be said in football when they're running. Any fast movement the quality is so blurry and atrocious.

Here is the "why" for the U.K. version of FW 5.80.10. It's all about the 2018 U.K. models:

What's the deal with the XBox-side settings from that post?
It recommends setting the bit-depth to 8-bit for SDR/HDR/DV. Surely you want the HDR/DV setting to be set to 10-bit to avoid posterisation? Am I missing something subtle there?

HDR forces 10bit automatically when HDR is engaged
SDR content is native 8bit.

Tried to update my EU C7 last night to 05.80.10 but it failed.
It runs through the entire update via USB, but at 100% the tv states "update failed, reverting to previous FW'.

Maybe a corrupt DL, will retry later today.

This is confusing. So has the 7 series update done anything to HDR Luminance or not?

The changelog says so also for 7 series, and I instantly noticed a difference compared to numerous previous HDR testing.

I'm not denying that something seems to have definitely changed, but what changelog are you referring to? The 2017 5.80.10 release notes mention something about only for "O18 models" whatever that means.

I'm about to upgrade my home theatre equipment and am looking at a Denon AVR-X2500H.

However there are many worrying reports on various forums including AVS Forum that there is a picture quality deterioration on the TV when connected to this AVR (and also AVR-X1500H).
It affects different TVs and in some cases also when in Bypass mode where no video processing is applied. It could be the Denon, it could be the TVs, it could be cables...

I want to ask before I bite, is there any one here with a B7 or C7 that has this AVR and do you see a picture quality reduction when watching external video sources such as Blu-ray?
Thank you.

Can you link to the particular reports? Are they related to a recent TV firmware update? If so, then it is almost certainly not the AVR.

Only person I've seen say anything being changed is P40L0. Everyone else says it's exactly the same on the 7 series.



The note is probably referring to the brightness fluctuations the 8 series had, as previously noted in this thread.

Vincent was very specific that this FW update - as it pertains to item #2 in the change log ( HDR Luminance ), was for 2018 U.K. models - and not the 2017 models. Both model years ( 17 & 18 ) will benefit from item #1 in the change log.

"018" = 2018

As a general rule, AVR's are not the best choice when it comes VIDEO switching/distribution. In some ways I wish they would take the "V" out of the moniker "AVR". With 1080P signals, it wasn't / isn't an issue, but with 18Gb-4K-HDR/HLG/DV/4:4:4 signals, it is a crap shoot. Depending on the brand and model, you will find a plethora of variations in terms of the quality of the video chipsets in the receiver. Some AVR models will use chipsets that employ DSC compression which actually removes 10 bit metadata even though they will pass 18Gb bandwidth tests. These are the cheaper chipsets. Other AVR's will use CSC chipsets which cost more, and will not manipulate the video signal, but at the same time they will upscale a 1080P signal even though you really want the TV to be doing the upscaling. Sometimes, you can turn that function off - depending on the brand and model - and sometimes you can't.

I highly recommend using an HDMI switch designed to pass 18Gb-4K-HDR/HLG/DV/4:4:4 signals unmolested. It should at a minimum have two full featured HDMI outputs ( HDMI 2.0 / HDCP 2.2 ) so you can have one signal going straight to the TV, and the other feeding to the AVR for supporting multichannel/object audio. The number of inputs will be based on how many external video playback devices you have. Most of us will have three - cable/sat box, Blu-ray, and a streamer.

( As a side note, there are streamers out there that do not support DV. Those are the one's to avoid because most likely they are using the DSC chipsets, as you cannot compress DV or you will not get a picture. )

Just my two cents.

They are not referring to the LG C7 specifically in any reports yet which is why I'm checking here first.
Yes, it is the Denon AVR as when people swapped to the new Sony STR-DN1080 it didn't cause picture deterioration.

Depending on the brand and model, you will find a plethora of variations in terms of the quality of the video chipsets in the receiver. Some AVR models will use chipsets that employ DSC compression which actually removes 10 bit metadata even though they will pass 18Gb bandwidth tests. These are the cheaper chipsets. Other AVR's will use CSC chipsets which cost more, and will not manipulate the video signal, but at the same time they will upscale a 1080P signal even though you really want the TV to be doing the upscaling.

And a very worthy 2 cents, thank you.
I didn't know about the switches, it is a good fallback if I'm unlucky to have picture deterioration, thank you for the suggestion.

Some questions about OLED light level for the native youtube app, should I leave it on 100 like it's recommended for HDR 10 sources?

I've read for HDR 10, OLED light should be 100 and for Dolby Vision, it should be 50.

I've also read we should put sharpness at 10 for these LG sets, as that is the true neutral setting. Does this also apply when the option comes up to adjust H and V sharpness separately?

Thanks for any advice, much appreciated.
It depends on the picture mode you are using as to whether you will have both H and V sharpness setting options. The default for SDR technicolor Expert is 20 and there is no H or V options - it's just plain Sharpness.

As far as OLED light settings go, I think you should adjust to what is comfortable for your eyes and viewing environment. There are purists out there who will probably flame me for saying this - because of tone mapping - but the problem is that you have to calibrate the TV to a particular mastered nit level, and if the content was mastered using a different level it makes tone mapping basically useless.
