No enhancements (heaven forfend), but just reading the posts above, I realise that ABL is likely. Dammit. I'm not monkeying around in the service menu.

I've turned off ASBL, but the "slow" contrast transition shifts are not something I've experienced either before or after turning it off.

What is being described is what I personally call "backlight pumping," which is indicative of the LED LCD tech. It's a trade off of the tech, just like ABL is a trade off for the OLED or any other self emmisive tech. I'm not exactly sure what you are experiencing, but that sounds slightly strange for the OLEDs.

In my experience, OLEDs will be able to do it's peak brightness initially and have a harder time sustaining said peak brightness, dimming slightly the longer it sustains. Not the other way around, where it takes a brief moment to get to its peak brightness.

This is the only time I've seen this phenomena (granted, so far I only have three 4k discs). Very odd.

It is ASBL, not to be confused with ABL, and it is the only thing worth going into the service menu to disable. On very dark content, such as the walking dead and unforgiven, it will engage and make things very dark and then have that delayed, almost an exaggerated LCD dimming/dynamic iris, effect when switching to a brighter scene.

Haven’t noticed it yet...

Ross, it's not often it would even happen. Not sure about the 2017 model programming, but I believe if you find a dark enough scene and you pause it for about 3 minutes, it will kick in (a gradual dimming) and then after you push play, watch for the brightness jolt when enough bright content hits the screen. 2016 models like mine had the timer programmed a bit shorter (about 90 seconds I believe) so it was noticeable every now and again. For your model it should be extremely rare to see.

Thanks, good to know. I’ve only had the B7 for just over a week but have watched quite a bit and haven’t noticed any fluctuations. I did mistakenly follow a few sites recommendations of leaving dynamic contrast set to low in its Technicolor Expert mode but have since turned it off.

At least every report I've read from professional Calibrators (Incl. D-Nice over at AVSForum) have recommended leaving the settings on Cinema User and Dynamic Contrast set to low to initiate Active HDR.

Yep that’s why I initially left it on but I read the AVSforum review and they said it clips whites. Rtings and Cnet also say turn it off. Cinema and Technicolor expert are very similar but I prefer Technicolor since it leaves all the processing off. I do use Cinema for Dolby Vision. I played around with Cinema Home and while it’s brighter, gamma looked way to bright.

tama · 04-17-2018, 12:15 AM

Not sure about CNET but at RTINGS they insist you turn it off for SDR content. Heres the link for our year models and if you scroll down to ACTIVE HDR section it explains why it's done this way.

https://www.rtings.com/tv/reviews/lg...-oled/settings

"The 2017 LG OLED TVs now support HDR with 'Active HDR', which is similar to HDR10+ or HDR10 with dynamic metadata. This feature analyses the content frame by frame in real time to adjust the HDR tone mapping curve. This has the advantage of displaying each scene with an optimized HDR effect, as opposed to the HDR with a static metadata, where all the movie was using the same tone mapping curve, resulting in some scene sometimes being too dark or too bright or simply not exposed correctly to have the best possible HDR effect."

I've never tried it any other way but it seemed that most places tended to go this route on these sets.

Wasn't there supposed to be a stand alone blu-ray release for this film shortly after the 4k release? Does anyone know if it's been delayed, or just not happening anymore? I don't plan on upgrading to 4k any time soon. I know this new release has a blu-ray, but would rather save a few bucks where I can.

Doubtful now. One of the reasons I upgraded.

Not sure, but I don't like how they pumped up the color on the remastered BD.

It seems only the WCL exclusive limited edition from China have the stand alone 4K restored blu-ray.

I don't know, I think that if you really REALLY want it, then wait for a sale, or just disregard the 4k disc.

What's funny is, I wonder what people would think if they said this same comment on the BR forums, but wanted a DVD, and didn't want to buy the blu-ray because they only want the DVD copy.

Except they didn't. It's just the correct color now. In fact, many scenes look almost identical and some scenes in the old blu are actually more saturated than the remaster, so this is complete nonsense. And everyone knows that most (if not all) 4K discs look different form the blu-ray due to color gamut and other factors, so you obviously can't compare the two.

You think it's "correct" now because that's what you want to believe.

Let me ask, what display are you using and what calibration tools and software were used when you carefully looked at these discs?

The UHD BD looks much more natural in a way that is not only attributed simply because of HDR and P3. The colors are pushed out in a number of scenes with the new BD that looks unnatural. I wouldn't say it's a bad disc by any means and it's certainly better than the original, but if the remastered BD was my best way to watch this movie I would be a bit disappointed.

I'm not sure it's worth going there mate.

People would probably the person was crazy.

The difference in image quality from Blu-ray to DVD is quite noticeable, unlike the one from Blu-ray to 4k UHD. The screenshot comparison thread is a laugh riot. One needs to use a magnifier to notice any difference between the formats.

Geoff D · 04-28-2018, 03:54 PM

Resolution isn't the only point of difference with UHD, trouble is those differences can't properly be gauged by SDR-converted caps...

Frank@Chicago · 04-28-2018, 03:55 PM

The saloon shootout at the end was very dark and as Clint headed out into the street, it was hard to make out anything on my C6.

My solution was to pop in the BD and rewatch the ending on that, there's an American flag in the background that you can see much better on BD as I recall.

Maybe the OLED auto-dimming did kick in, I've only seen that happen when I pause content (for screen protection).

Honestly, I'd be reluctant to disable that feature but I'll keep it in mind for my next watch of Unforgiven.

There may be a simple way to 'fluff' the display by pausing/unpausing or entering Settings.
