My refresh comes in the next 2 weeks so hoping nothing comes of not having it reset.


Will be interested to hear what happens...

I’ve come across dark, with the DV glitch, but never so dark I couldn’t see anything. Ozark and Haunting of Hill House both are dark shows with DV I’ve seen the “glitch”, but the extra lighting wasn’t such a dramatic change (IMO), just giving my personal experience (I have ATV4K as well).

I just saved a guy, he thought he had to buy a new TV, I asked if he used a credit card that extended the warranty, he said he had to check. He checked, said it did, he did not buy a TV. A little knowledge goes a far way, I saved him from buying another TV..... A true dealer watches his clients back, end of story.

Hey @sonoftumble I've been lurking this thread for awhile looking for ways to improve my viewing experience on my LG C7. I came across your calibration settings and have been using those, but don't have access to your Dolby Vision calibration file. Since I've been a lurker, my account has no posts. Is there any way you can PM me so I can reply with my email? It would be much appreciated, I'm sure your calibration file would make Our Planet on Netflix look even better!

I’ve noticed when watching HDR10 content on Netflix, some content has intermittent flashes in the letterbox part of the screen. It happens on the newest season of Sabrina, for example.

Hard to tell if it’s a Netflix, Roku, or LG problem though...


EDIT: did a test and I’m seeing it in SDR too, and outside of the letterbox. I think it has something with how the set is resolving detail in dark scenes. Looks like it was a problem on the 2018 sets too. Basically seeing what’s in this video.

HAPPY LABOR DAY!

The settings below are ALL NEW except for HDR10 technicolor Expert.

NOTE: This will probably be my last settings hurrah on this thread due to the fact that our sets are now out of production, and firmware updates from LG will no doubt be prioritized for current models; i.e. 2018 - 8 series. If something comes out that radically changes things, then I will take another look and run new calibrations. Otherwise, I think this is a wrap.

With that said, most 7 series models should benefit from the settings below. This is assuming that your panel’s performance / specs are fairly close to mine. Variances in panels may yield different results. For most of us, it should be very close. If the variance is less than 3%, you will enjoy an awesome SDR and HDR picture.

These are actual meter based calibration settings ( vs. disc based ) using a recently certified ( June 2017 ) Spectracal C6 meter, Murideo 6G pattern generator, and CalMan for Biz 2017.

SDR notes: A few days ago, I ran a calibration recheck to see if my TV’s colors and gray scale had drifted since the January calibration.  There were very few differences - which is good news.  I decided to spend a little more time, and try to get things as close to perfect as possible.  As you will see with the attached Post Calibration screenshot for SDR technicolor Expert, things are almost perfect. On top of that, the adjustments to both the White Balance and CMS are extremely minor and well within single digits from the zero point. The SDR picture on my C7 looks phenomenal.

Dolby Vision notes: This is an ENTIRELY NEW revamp. The problem with the previous DV calibration was that I was allowing the EOTF curve to meander around like a river carving a new path. The delta errors looked good, but the gamma was all over which effected luminance performance especially in the lower and mid luminance ranges where most content lives. The general complaint about the Dolby Vision "Cinema (User)" picture being too dark has been eliminated as the 2.2 gamma target is now flat across all IRE levels. This made a huge difference in the overall brightness of the picture while still providing those spectral highlights that everyone expects with HDR content. Again, I am very pleased with this picture, and it looks much better than the previous revision.

The Calman “DV custom" workflow allows the calibrator to create a special file just for 2017 LG OLED’s, which is saved to a thumb drive and then loaded into the TV. Spectracal, Dolby, and LG worked very closely together to create this awesome workflow. It’s actually faster and easier to go through than an SDR calibration. The DV “custom” workflow focuses on greyscale and once the 2 point and 20 point have been adjusted, Calman then creates the file ( plain text ) and the calibration session is complete. There are no other adjustments, and the CMS is left untouched.

If you are interested in taking a closer look at this file, you should send me a private message with an email address so I can send to you.

For those of you who have already received the previous DV file, I have already sent out a new one with the same settings as listed below.

Updated SDR post calibration screenshot attached.

Low - R: 0, G: -1, B: 0
High - R: -5 G: 0, B: -1

NOTE: (I skipped the 5, 15, 25, etc. IRE settings because it was not necessary to adjust those in order to achieve an almost perfect grey scale reading. Leave them all at zero.)
Method: 20 Points

ISF OLED LIGHT SUGGESTED SETTINGS - SDR - LG OLED 7 SERIES PANELS
BRIGHT ROOM:
OLED LIGHT @ 49 = TV Foot Lumens of 55 ( Range 50-60 )
DIM ROOM:
OLED LIGHT @ 36 = TV Foot Lumens of 45 ( Range 40-50 )
DARK ROOM:
OLED LIGHT @ 25 = TV Foot Lumens of 35 ( Range 30-40 )


HDR10 Settings
HDR-10 Picture Mode: technicolor Expert

BASIC SETTINGS:
OLED LIGHT: 85 (Default: 100) This setting will vary depending what nit levels the content was mastered as well as room brightness. There’s not really a way to know the mastered nit levels of any given title without a Lumagen which can read the metadata. So this is really a “how does it look to you” kind of thing. 85 seems to be a “happy" medium, but there's also eye comfort levels to consider.

Sorry no. There's enough differences between the two generations to render my 7 series settings mute.

I was at a friends house yesterday, and he has an uncalibrated 77" C8 ( jealous!! ). I set the picture mode for SDR and HDR10 to technicolor Expert, Warm 2 - and things looked fantastic. For Dolby Vision, I used the Cinema ( not Home ) picture mode, and again the picture was fabulous. So there's a ton of out-of-the-box improvements with the 8 series panels.

Later this week ( if I get the time ), I'm going to calibrate using the auto-cal workflows that were developed by Calman for the LG 8 series OLED's and see if things look even better. I'll post my opinion and maybe I'll have some settings.

I don't know if some of you have observed that the bezels ( I own a 65" B7 ) can change in thickness depending on source. Can you confirm it ?

7 series supports the low latency version of DV (for now at least).


Honestly, Dolby Vision is a mess. When it's working right it's great, but there's still raised black issues, and there's HDMI sources (like Apple TV 4K) that output a brighter picture than internal apps or even other HDMI sources for that matter.



I often just opt for the HDR10 version of stuff so I don't have to play guesswork with if the image is being displayed accurately.

As the source says, this is an issue with 2016 LGs only—aka the 6 series. The 7 series should be fine.

The article is also fuzzy about the exact issue but it sounds like XBox is only choosing to output the Low Latency version of DV and imho it is an xBox not an LG issue (seems like the ATV can support both versions afaik.)

This stupidity started as far as I can tell by Sony, who’s sets only supported the Low Latency version, and now it seems like that is becoming the least common denominator of DV—and what else did Dolby expect. It also seems like this is NOT new but finally a definitive statement from LG that those older sets will not support that version of DV.

My best guess is that LG and Dolby could fix the 6 series but they are choosing not to most likely for economic reasons. I doubt it is a technical issue.

I thought the Apple TV also already used the low latency profile, and as far as I know it works with the 2016 LGs. It seems more likely the 60Hz DV output would be a problem since the 2016 only supports 30Hz DV. The dedicated DV chip is probably just too slow for any more in the 2016 LGs and the other 2016 (and some 2017) models from other companies.

You might be right. It is very unclear from the article.

We do know that ATV did NOT initially work with Sony TVs and did not output that profile. What I don’t know is if the ATV can output multiple DV formats. I suspect it can.

We also know that ATV can drive 30hz DV to the the 6 series. I don’t know what profile it is sending.


So is the issue that xBox just won’t output 30hz DV. If that’s the case I’d say that it is still an Xbox issue. But if I were a gamer I’d prefer 60hz hdr10 to 30hz DV anyway so this “issue” may not really be an issue at all.

Without more detailed description of the issue from the source this is a guessing game and I’m completely unclear if this is an LG issue at all.

@sonoftumble Can you also PM me please so I can send you my email.. I am also a lurker with only one post and cannot PM you

Really appreciate the hard work you have put into the calibration and excited to see the results on my set.

If the device does not support DV then yes, otherwise all apps default to DV.

With a Roku, wouldn't the HDR type (HDR10 or DV) default to whatever the show was mastered in or does Roku provide a way to force HDR10 and does some sort of conversion for DV content?

No. Netflix provides HDR10 versions for all devices that don’t support DV. No current Roku has DV support.

OK, so basically there is no dv "on/off" switch.. If a device supports dv it will always play in dv and if it doesn't support dv it will always play in hdr10

There are a couple where you can turn DV on/off, but unless you have a few hundred to ~$1K lying around to buy one it’s not possible. All streaming defaults to DV if the equipment is DV capable. You’d need a device that can force HDR10 or only does HDR10. So what you now say is correct.

Honestly, Dolby Vision is a mess. When it's working right it's great, but there's still raised black issues, and there's HDMI sources (like Apple TV 4K) that output a brighter picture than internal apps or even other HDMI sources for that matter.



I often just opt for the HDR10 version of stuff so I don't have to play guesswork with if the image is being displayed accurately.

The Xbox should simply provide an option for Player Led or TV Led like the Oppos did.

I'm worried about my b7, just watching game of thrones on blu ray and noticed a line across the screen a few inches from the top. It looks the same place a letterbox would be, however no line at the bottom. I've never seen this before. Also I haven't updated the firmware or changed settings recently.

Also using the same settings as always, it seems darker somehow. Blacks seem to be crushing where they never did. I tried watching an episode I watched last night and I don't remember it looking so dark. When I switch to game mode I can see details in the shadows that are lost when I watch on any other setting, however game mode makes the blacks look washed out. I've tried unplugging and replugging the hdmi, switching off and on at the mains. No change.

A few weeks ago I had an issue after switching on when it started with a picture like a photo negative. Switching off and on at the mains solved the issue. Just worried if this is a sign the TV is dying? It's only 16 months old, 3 or 4 hours viewing per day.

Bluetooth Headphones Audio Synch

If I buy a set of headphones (considering the Pawws Wavesound 3) with aptX low latency will I need a Bluetooth transmitter to use with the TV or does the set support aptX low latency? I have done some searching but cannot seem to find a clear answer to this question.

My B7 died last night, won't power on, red indicator light just blinks then screen is blank. Did it 2 weeks ago and called in and they had me unplug and hold the power button for a min and it came back up, no luck this time. ~15 months old maybe 10 hours used max per week.
Bought it from Costco so I've got a 7 year warranty with square trade and my CC. Supposed to have someone call me to setup an apt to fix, have to take it off the wall mount myself and put it back up which is lame. Wondering how long I'll be out of a TV before they can fix it.

Recently got my panel on my C7 replaced since the vertical banding was affecting up to 15% grey and I even noticed some awful vertical banding / discoloration in yellow / orange heavy scenes (like the desert in the first episode of Star Trek: Discovery). New panel is looking nice, though the near black crush seems worse than the old panel. Not a huge issue considering how bad the bands had gotten on my old one. But I am one day away from my 1 year warranty being over, so I was curious if LG provides any additional warranty time after a panel replacement, like 3 months after the repair or something? Just in case of a worst case scenario where after settling in for a couple hundred hours the panel starts to show some issues.

I believe I remember reading several pages back of a forum member who has gone through three panel replacements. I had one myself. Mine had very few hours and it became terrible and the repairman said he is seeing a lot with the panels darker on one side than the other, which was my problem. My new panel is good so far, but I did buy an extended warranty after he told me how much just to replace the panel costs! It seems it may be a look-up table problem but LG replaced the panel, so I hope it doesn't show up again but I'm covered if it does.
