I probably wouldn't be saying that if the launch price hadn't been so good.
When are the 2018 sets expected to be released? I just bought the LG b7 at Costco but I have 3 months to return if needed. Although it looks like they are gonna cost a lot more than these do right now

When the sun goes down, I can get the room pretty much pitch, so that would make more sense that I found myself turning down the OLED LIGHT to 70 for HDR technicolor, and raising it to 70 for DV Cinema (User) - ( 50 still just looks too dim ). Those settings are basically intended for a darker viewing environment.

For SDR, I have the OLED LIGHT set to 49, which not surprisingly works well in a med bright to bright room.

You might ask why the OLED LIGHT is lower for SDR than for HDR/DV even though that's a daytime setting? The simple answer is that SDR/HDR/DV use different scales and the HDR/DV thresholds start at a higher luminance level.

So now I can see the confusion that I may have caused. Keep in mind that my settings are generally middle range, so I think that they look great under a variety of lighting conditions. For me, it's a "set-it-and-done" kind of approach - or a happy medium.
No worries...and no confusion caused. Just gotta find my happy medium since my room also ranges from reasonably bright during the day to pretty dark at night-time when we watch movies. Already re-adjusted HDR10 back to 70....need to fix DV back to 50 or so and see if that helps.

Yeah...going to play with it. Thanks

Yeah there's some settings in the FAQ thread that I'm gonna look at. I keep reading about higher OLED light settings for HDR content... but like I said I've been pleased running at 16 in my dark room setting (usually complete darkness) for both SDR and HDR. Still, I'm curious and want to see how it looks.

The C8's will start shipping in two weeks. The B series is a retail OEM model for Costco and BB - but somewhat similar to the C series and usually better priced.

Ah ok thanks! It's a pretty big price jump from the cost of the b7 now. Worth it? I think I'd rather trade up to the 65 inch b7 instead for the same price but we will see. Do you think the b7 will drop even more when these are released or they will just stop carrying it?

What's the difference between the c7 and b7 now or for 2018? I keep seeing that it's mostly just cosmetic or better sound but a little confusing

... and according to what I read, the 2018 B series will not have the same A9 processor as the C series.

Worth returning the B7 I bought a month ago for the B8? I don't think so.

Yeah I think I agree especially if they don't have the same chip and it's gonna cost so much more for the b8 I'd imagine

The PQ is stunning... running expert (dark room) for SDR and Cinema (user) for HDR. I basically took the rtings.com settings and slightly tweaked them. I haven't experimented with Technicolor yet.

Anyways, it's all good... just seems like every post I see people are running their light at 50-100 and mine is 16. Hope I'm not missing too much.

P.S.

Wanting to protect against BI doesn't have a thing to do with my choice... I just don't care for bright displays.

I certainly wasn't impressed... but I went straight from plasma to OLED... skipping everything in between... (LCD I think?)
The "QLED" logo is very misleading and obviously designed to fool the uneducated into thinking that it's also an "OLED". The reality: just another edge lit LCD panel that almost the entire industry has moved away from.

Just for reference here's the readings I took from my C7 for SDR OLED LIGHT settings, and the ISF luminance standards for various lighting conditions. These are all mid-range for each level. So as you will see it's OK to set the OLED LIGHT pretty low . . . . I also attached a screenshot from the Calman calibration workflow. For me the bottom line is to not make your TV work any harder than it needs to.

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 )

According to LG the B8 will not have the more powerful chip. That will be in the C8 and above models

Yeah Samsung might fool my tech brain dead Mom... but not me. As I said upthread she's looking for a TV and the first thing I told her was the differences between QLED and OLED.

Thanks for the info on the settings. I agree too... don't care to push the TV if I don't have to... and I've been happy with the light at 16 on both SDR and HDR content for a month now. If it ain't broke don't fix it probably applies here, but I'm still gonna have a look at your settings in the FAQ thread because I'm curious.

Yeah I use 70 for both hdr10 and Dolby vision. It’s bright enough to be near blinding when a bright highlight is against a dark background but slightly toned down from 100. I could use 100 and be fine but it seems to me that 70 is a happy medium.

Yes, you are correct, those settings are for SDR, and are tried and true. As @Bumtious noted, is took us 20 years to finally get REC.709 right. Hopefully it won't take that long to get HDR/P3/Bt.2020 under control! LOL

The SDR luminance settings also go hand in hand with gamma curves. Currently, HDR calibration workflows use EOTF curves. So right now, things are pretty much subjective and dependent on individual preference. For HDR/DV. set the OLED LIGHT to what looks good to you. Some people out there either actually like the OLED LIGHT set @ 100, or they have convinced themselves that they are preserving precious tone mapping continuity. As I've said before, that setting makes my eyes water after a couple of hours of watching. Also, as I've said before, I don't like it when a desk lamp with a 25 watt bulb looks like it's packing a 100 watt bulb. At that point, it's time to turn down the OLED LIGHT!

Now, the good news is that we will be abandoning EOTF and returning to traditional gamma curves in the not too distant future. Those methods and workflows are already undergoing closed door development and testing at several major TV, playback, and content delivery companies.

HDCP is software that deals with the encryption. Cable has nothing to do with it.

HDMI 2.0 supports 18Gbps. 2.0a and 2.0b just add some extra features to do with HDR. Same cable since it is the same link, just changes in the software specifications for handling the port.

HDMI 2.1 supports 48Gbps, and that needs new cables. Of course HDMI 2.1 devices don't have to use or support 48Gbps, so you might be able to use an HDMI 2.1 device and all its features with an existing cable just fine. This is why the HDMI rules state cables can't mention the standard number, because that isn't the speed. The speed grades have names:

Standard HDMI (3.96Gbps), High Speed HDMI (10.2Gbps), Premium High Speed HDMI (18Gbps), Ultra High Speed HDMI (48Gbps). Cables also have rating for supporting Ethernet or not. Most cables do, and I believe ARC requires a cable with Ethernet support since the same pins are used for both features. Of course nothing uses the Ethernet feature. A cable might handle more than it was rated for, but often it does not.

Not the 75Z9D, those have a great price over OLED 77".

Likely no warranty as it’s probably not an official retailer.

2017 LG C7-B7 Owners' Thread (No Price Talk)

Question about contrast settings and HDR. How do we know if 100 is the proper setting or if we need to go down to 85 or whatnot? Does this change with hdr10 vs Dolby vision? Should I just leave it at 100 and be done for both?

I believe that's a bait and switch site.

You really shouldn't be messing with the HDR settings much beyond sharpness, motion, etc. unless you have the equipment to do it properly. Things like contrast should be good at default.

According to what sonoftumble seems to indicate, it depends on the panel and a setting of 100 may actually be clipping but on another it would be correct. Is that not what I read?

Is this for HDR streaming and 4K Blu-rays?

How many times does a Mod have to post a reminder about no price talk (ex MSRP)?


The deals thread exists for a reason

There is no perfect display, quit looking for faults and enjoy

This is for the whole chain from mastering to the end display, and everything in between.

EDIT: The good news is that it won't cause a problem with existing content or delivery infrastructure. So today's Blu-rays and streaming services will not have to be modified. It's more along the lines of how the TV interprets the luminance data and applies the gamma curve. Basically a FW update.

Do you suppose that the not too distant future might happen in 2018, and might be included on a firmware update for 2017 model units?

Lol. Somehow I doubt it. Especially when the press and manufacturers marketing is nits nits nits.

The pro world and content creators know that their work gets mullered out in the real world.

It’s an education trying to help people understand how much better and detailed an image could be with the levels intended by the content producers
