First impressions a little mixed. I can't really see the HDR Optimizer doing much. I think it's likely because most of my UHDs are probably mastered to 1000 nits anyway. I know the one exception is Blade Runner 2049. I honestly couldn't see any difference there either in the scenes I tried. But that still might not be the movie that highlights what the HDR Optimizer can do.
On another front, I'm not sure I agree with Vincent Teoh's suggestion to turn off the dynamic tone mapping of the LG C8 when using the optimizer. Every scene I tried it with looked better with dynamic tone mapping on. I saw his video where he displayed the differences with DTM and the optimizer in that scene from Pan. But that was a very high nit highlight. I wish Vincent would have tried a combination of the 2 to see what the results would have been.
What I'm seeing is that while the DTM might not do as good a job tone mapping from 4000 down to the 700 nit capability of the OLED, it works differently when it is tone mapping something that is much closer to it's capabilities.
In other words, let the HDR Optimizer do the tone mapping down from 4000 to 1000 and then let the DTM do it's work from there.
I'm just unsure about the whole thing.
The player also locked up badly in a scene from Midway, which I rented yesterday from Redbox to try on the 420. I cleaned the disc further and it still locked up at exactly the same place. I hooked my 800M2 back up and played the exact same scene and it froze for a couple of seconds and then continued. It handled it better, but I think there is something up with that particular disc. It is too much of a coincidence that both players had some sort of problem at the exact same spot. The 420 tends to be more finicky in this regard though. However, the Sony would randomly lock up every now and then even with pristine discs that I knew worked perfectly elsewhere. Which is one reason I was looking to switch players in the first place 😕
On the plus side, the upscaling in this thing is great. I tried out some Blu rays and they look nicer here than the Sony or the LG UBK90.
Hmmmm. Im thinking of adding one as a secondary/backup player. My UBK-90 is still doing me good but I like to have a backup player. Overall, are you happy enough with it? I wonder if the Sonys are also worth checking out? Or I just get another UBK-90 which has treated me well.
I watched a couple of more movies and had no issues with playback. I'm pretty sure my problems with Midway were specific to that disc.
I decided to rent Mad Max: Fury Road 4K UHD from Redbox. It's been a while since I saw it and it was one of the discs used by Vincent Teoh to demonstrate the HDR Optimizer.
I paused the movie in the same scene Vincent used in his test in this video:
The sandstorm scene with the exploding vehicle.
So this was a case where just like in the video, I could see the HDR Optimizer make a difference. Since setting the TV to to OLED makes the player tone map down to 1000 nits, and since most discs are mastered at 1000 nits, then it makes sense that I was not seeing a difference with the discs I had at home. It's really only going to work with certain titles. Mind you this is on OLED. With a projector you will see even more of a benefit.
Now what I did was I tried HDR Optimizer by itself, Dynamic Tone Mapping by itself, and then the two combined and I looked at the detail in the explosion. As I suspected, the combination of the 2 gave the best results on my C8.
The optimizer by itself did better than DTM by itself. But there was still some missing detail. Adding DTM on top of the optimizer brought out a little more detail in the center of that explosion. I think the Panasonic does a great job tone mapping to 1000, but the DTM does a better job tone mapping the image from 1000 down to around 700 than the TVs native tone mapping does.
So yeah, I'm going to disagree with Vincent on this one. Even though I'm not a professional calibrator and he's forgotten more about this topic than I ever knew. He's right that you should not use the DTM in place of the optimizer. But he failed to test both in conjunction and it clearly gives the best results in my setup.
I should note here that my C8 is not professionally calibrated. Maybe after professional calibration using the optimizer alone would bring out all the detail and there is no need for DTM. I can't speak to that.
So to answer your question yeah I like the player. I think that you won't see much of a difference in performance between the LG and this on most UHD discs. But on those discs with very bright highlights, it clearly performs better. And I do think it upscales better.
