I didn't mean to come off as dissing the opinions of pro calibrators. My point was that it's OK to adjust the OLED LIGHT to a level to looks the best to you, and provides a certain level of eye comfort. Of course this is all very subjective.

The dilemma is that with HDR10, the studios do not master all content at the same nit levels. In fact they are all over the map with some mastered at 2,000 nits, and some at 4,000 nits, and some at 10,000 nits. The LG 7 series TV's max out at around 700 nits, so tone mapping is necessary in order to compensate for those gaps, but it will not work across the entire range of content due to these varying nit levels.

The higher the mastered nits, the darker the picture, and the lower the mastered nits, the brighter the picture. This is what I meant when I said that tone mapping is useless. If we want HDR to look and feel natural, it will need to move toward the hybrid gamma curves found with formats such as HLG and Advanced HDR by Technicolor. Neither of these formats employ any level of tone mapping, but they simply allow the luminance levels to change based on the capabilities of the display. In other words, they don't try to force mapping to an arbitrary nit level.

Most of the factory settings are designed to get the most nits out of a particular panel for marketing purposes. After a set is calibrated, the total nits will be quite a bit lower than what the spec sheet claims.

If we could change the gamma with DV and HDR, I would recommend raising it to 2.4 or BT.1886. But we can't do that, so instead we have to mess with the OLED LIGHT. A couple of months back, I was watching "Darkest Hour" on my AppleTV 4K in HDR10 ( HDR technicolor Expert picture mode ), and there was a scene with a desk lamp, and the bulb looked like it was 150 watts when in reality it should have been around 40 watts. There were many scenes throughout that movie where things were uncomfortably bright - and I'm not talking about explosions, etc. - but just basic indoor scenes. At that point I took a closer look at the picture mode and noticed that the OLED LIGHT was cranked all the way up to 100 by default.

I lowered it to 70, rewatched several scenes, and found the visual experience much more enjoyable, and less headache inducing.

During the daytime my viewing environment is med bright, but at night is gets plenty dark so I also have a bias light.

At this point, I'm keeping the DV backlight at 70 for day or night, but I lower the HDR light to 70 at night and raise it to 80 in the daytime. That doesn't happen too often, as the TV will be tuned to regular SDR satellite during the day.

Sorry for the long winded answer.

A little but there weren’t obvious problems before.

Prior to calibration I had set SDR black level, ie, Brightness, using the AVS test pattern disk.

This is NOT to say that your TV looks wrong, but that variation between sets and what they need for perfecting grayscale and CMS can vary significantly.

Without measurement gear and skill, imo it's safer for people to just choose the Technicolor preset and feel confident it's as good as it gets without measurement gear.
Did near black detail change, after calibration? I have some issues getting near black detail to show without making black glow.

This is in part due to that fact that most people live in areas with very high 2.4GHz congestion.

Is your router N or AC?
Applied .90 awhile ago, wifi seems to function fine...after installing, played with some DV content via Netflix and found it loading fast with no buffering. Afterwards, I then followed Datagg's video from a page or so ago and changed both the 2.4 and 5g channels to lessen interference. Happy with everything right now, but I'll reserve judgement that this is permanently fixed after putting a few more miles on BTW, router is an N.

I think I used your 2,20, and CMS. If I wanted to reset them to factory do I just set them all to 0 or do I have to do a reset? If I reset does it reset everything or just that Picture Mode?

You could go either way. However, there is a reset menu item for each picture mode which will save you time. Just go into the picture mode where you can set things like Color, Contrast, etc. and scroll down to the bottom. Can't miss it. I would continue to use the 2 and 20 point as grey scale is pretty consistent across all panels. Color is more variant.

Scratch the Dolby Vision being too dark thing....I had messed with the Backlight of the Vizio which was causing the Vizio to show DV too bright (even though the charts read it ok).....after recalibrating they are both pretty similar now.

Sorry for the delayed response. This should be the very first thing one does when they get their new TV. The improvement it made to picture quality was immediate and dramatic! Thank you.

Anybody know if ISF Bright and ISF dark are the same? I have one of those professionally calibrated and was wondering if it will be ok to copy it over to the other one without any issues?

They may have different defaults, but there's no inherent difference between them. If you copied every setting from one to the other the output would be identical.

Ya, the 75X850E is a big nice standard set, will rock an OLED though.....Guess you are the "quality" kinda guy

I'll let you know what I think of the above on my calibrated panel... my UHD copy of Darkest Hour arrived today.

Chad B calibrated my 65 B7 for each... for ISF bright I turned all 4 living room lights on.

For ISF dark all the lights were off when he was doing the calibration.

I believe the OLED light is 80 and 49 for each but would have to look at my settings spreadsheets.

Its handy to switch between the two because the girlfriend likes watching SDR movies/TV in the dark... except when she's eating dinner or something and has to have lights on.

As for the differences between ISF bright/dark and technicolor... he says there is none once calibrated.

(For those who don't get their panel professionally calibrated the technicolor mode is best out of the box)

^yes. Although it's your preference, that setting is probably the most inaccurate one out of all of them.

jrref calibrated my C7 to OLED=80 for Bright and OLED=35 for Dark, with Gamma=2.2 for Bright and BT.1886 for Dark. (No idea what the built-in defaults are.) That was before Technicolor Expert was added via firmware. I find the Bright setting uncomfortably bright outside of the couple of morning hours a day where our room catches maximal sunlight (at which time we're almost never watching TV or movies). So after the firmware added Technicolor I set that to OLED=50 and Gamma=2.2 (matching jrref's Brightness/Contrast settings), and that's what we use most of the time now. I didn't mess with the color settings for Technicolor at all, but I can't see any color difference between vanilla Technicolor and the calibrated ISF modes. Probably someone with well-trained eyes could, but I can't for the life of me. 50/2.2 seems like a great backlight/gamma combo for broadly typical viewing conditions - maybe some reflected light or a dim overhead, but not bathed in direct sunlight nor pitch black with light control. I rarely find myself switching to ISF Bright/Dark.

Gotta say... 9 months in and I still love this set. Best tech purchase I've ever made.

Is this set capable of doing Dolby Atmos over the HDMI ARC? I have it hooked up that way to a Samsung Dolby Atmos sound bar but I'm not getting the message on the sound bar that it's dolby atmos like I do from my Xbox and my 4k bluray player. I want to be able to watch my digital movies that are Dolby Vision enabled from the tv app for Vudu but am trying to get the sound right.

Yeah I've seen all the excitement about technicolor but I've never tried it... because he told me "ISF and technicolor are different from the factory... but they calibrate the same." No reason to question someone with the AV experience he has. The PQ is stunning.

Same here... I'm 4 months in and I'd rate it right up there with my sick gaming PC... which is still chewing up everything I throw at it and more a year after I built it.

I'm good to go with the B7 probably till 2020 or so then I might want to upgrade.

Same here,


I still use 49 or 50 depending the movie. Example I've got the 3 Expendables movies and the first one is at 49 the second at 50 but the third is not watchable unless at 47. Got my UHD titles stats on my phone with different brightness settings so I just check before revisiting them.

Expendable 3 has elevated black levels in the mastering process. It’s a known problem

Yeah, that's the thing with OLED we get spoiled with perfect blacks, and sometimes uhd movies are mastered with elevated blacks and that will drive most of us crazy!, A good example was a few months ago when SW TLJ came out people including myself were wondering what was going on with the space scenes...but that was intentional.

Has anyone noticed that when Technicolor and ISF Dark are set at BT1886 with all other settings the same that ISF is just a touch darker?. Might use that and see if I can get rid of the 49-50 brightness I'm doing now.

Good luck.

I can try this but it's just very strange that only the TV is having problems. I could see this solving the issue if multiple devices were losing signal but when only one thing is, it's clear where the issue lies. As long as changing the routers channel doesn't mess with anything else, it can't hurt to try. I'll do this once no one else is using the internet here.

Checked. Didn't pop the DV flag for me, though Stranger Things Season 2 does. Maybe it's a Netflix problem. But I rarely watch Netflix myself, so I may be missing something.

Yes, it’s working great with my Onkyo TR-NX676 5.1.2 setup, tested with 65C7 built in VuDu app and Dolby Access app.

Yes. I does pop on with Season 2. Season 1 does not appear to be in DV. I also checked on my AppleTV 4K and got the same results. DV = YES for Season 2, NO for Season 1.

B7A Technicolor SDR Gamma Recomendations

I have a slight dilemma with setting gamma across multiple sources for SDR content. Majority of my viewing is done on an Apple TV 4K, in SDR, with Technicolor Preset set to default settings. My girlfriend and I watch programs from "golden hour" until later at night, and we were having difficulty making out any shadow detail with the default BT.1866 setting, so I followed @sonoftumble 's advice in earlier pages of bumping the gamma to 2.2 for mixed usage. This seems to work really well, as even when my room is "dark" the TV itself generally lights up the space pretty significantly (it's only 8' with all white walls.) Most content is improved under these settings, the contrast is still deep but more natural with better near blacks.

Yesterday I just purchased a Sony X-700, which I'm using mostly to send my small blu-ray collection to the LG OLED as a non-upscaled 1080p signal. When I used the SDR settings from the Apple TV, I was seeing a lot of "nasties" in the shadow areas on some BDs, typical compression artifacts that the OLED really exposed. I found that by bumping the gamma back to BT.1866, even during the day, that the picture was greatly improved, without the "crush" of the Apple TV was experiencing under the BT.1866 setting.

Is this typical for gamma to have varying results across sources? I don't mind the setup I have now between the two devices, but it would be good to figure out what's going on here so I can keep it in mind if I add another source.

LG OLED55B7A | Apple TV 4K | Sony UBP-X700
Pioneer Sx-750 | TEC TC-7220 | Kenwood VR 507 | ADS 500 Acoustic Suspension Speakers
Denon DL-110 | Technics SL-1700

Apparently a lot of samsung atmos capable soundbars do not support atmos from arc at all. Many people are complaining about it. Which model do you have?
