For DVD-Video and non-Java (Ultra HD) Blu-ray Discs, the player remembers the timestamp at which it was paused for as long as the disc is still in. Most (Ultra HD) Blu-ray Discs with Java store the timestamp in the player's storage so the next time you use the disc, it will access this timestamp and allow you to resume.

I would suggest taking a look at some UHD blu-rays, particularly Disney ones, with the Dynamic Tone Mapping "On". To me, it makes a great deal of difference in showing more specular details while still maintaining great contrast and brightness. With it off, I feel like the picture is way too dim, especially on the Star Wars films. With Dynamic Tone Mapping "On", those films look like they should.

Invest in an affordable colormeter and calibration software and avoid the guess work. Measure both on and off to see which one tracks closer in eotf and roll with it. Unless you care more about preference over reference, then disregard.

Well, yeah but most people don't have that type of money. Even with an affordable colormeter, it's still tricky to calibrate HDR vs. SDR. That's why I leave it to the expert calibrators. My set is already calibrated so I don't have to worry about it.

I've tested both ways and even setting the Panasonic Optimizer at a lower setting (like Basic Luminance). Nothing really seems to look right until I turn the Dynamic Tone Mapping "On". Again, as I said earlier, the Dynamic Tone Mapping is LG's own version of Dolby Vision for HDR 10 Content. Is it perfect? No, but it looks better than just having the TV dim the overall picture down.

I have the c8 and LG's dynamic tone mapping is pure garbage. Eotf tracking is way off as it evaluate the eotf for an overall brighter picture. To the untrained eye it may appear better, but it's far from anything I would call accurate. Supposedly newer models have been improved, but I can not say for sure as I have not measured any newer models.

And that's why I said in a previous post the the older LG OLEDs (C8 and lower) may not have the best results when activating Dynamic Tone Mapping. This is especially true with the C7 when you have to activate DTM by turning "Dynamic Contrast" On.

The C9 and CX seem to have way better Dynamic Tone Mapping. It doesn't just make the picture brighter. It essentially adjusts the picture to the optimal level to display all of the specular highlights, very similar to Dolby Vision. It's not perfect by any means because the algorithm interprets some content improperly. Hence why I also use the Panasonic Optimizer at the same time. The Optimizer takes care of the things that the TV cannot, like over brightness and blown out highlights in the higher nit graded HDR content.

Not too shabby; universal 4K HDR Blu-ray players from Sony.
Try that with Panasonic.

Most people are going to use the Panasonic 4K UHD players for 4K UHD Discs. That's what the main function of these players are for anyways. If someone wants to play CD, SACD, and DVD Audio, I'm sure they could find an older player just for that. The Panasonic 4K UHD players are excellent. Hands down, the best players on the market since the Oppo 203. And since those aren't being sold, Panasonic is the best players out there. The Optimizer alone makes it worth buying!

But I know that already, as you knew about Sony not giving up.

And there is the Pioneer LX500 ...

Without a doubt, the Panasonic UHD Players are the best available now for 4k playback with top audio and video.

I just acquired a ub9000 last week so forgive my ignorance, but has anyone actually done this FW upgrade?

Forgive me if Im out to lunch on this as I have a pretty primitive understanding of all this and really have been out of the information gathering game until I bought my CX last November.

Isn't the issue with HDR10 itself? I was under the impression that you need a device, either the player or the display, to be doing some sort of dynamic tone mapping as I thought the primary issue is that HDR10 is flawed in itself since there's no scene to scene variation like DV and thats the whole reason the optimizer on the Panny players exists and DV gets its reputation as the superior option.

I have a CX and an 820 that I've paired together and while I can definitely tell that the Tone Mapping on the CX changes the image, I can't really say if its good or bad and have had it off other than trying it out.

It's not really "dynamic tone mapping" but just plain tone mapping. For today's TV sets, in order to truly enjoy HDR 10 content, it must be tone mapped. Most TVs naturally tone map without activating any function. Obviously, some TVs tone map better than others.

Now LG OLEDs have a feature called "Dynamic Tone Mapping." This is separate from the natural tone mapping your LG TV does. From my understanding with it since I have a C9 myself, Dynamic Tone Mapping is, in a sense, LG's version of Dolby Vision.

Now HDR 10 Content is static metadata. This means that when you play the movie in HDR, the TV just displays the overall brightness/contrast at a single level that works for the movie or content overall. Dynamic Tone Mapping on the other hand takes that metadata the HDR 10 Content has, interprets every scene and adjusts the contrast/brightness to make sure it shows all the specular highlights yet still having proper brightness/contrast to properly display the movie. This is why it's called "Dynamic" Tone Mapping. It's changing the contrast/brightness throughout the movie, very similar to Dolby Vision.

Again, it's very similar to Dolby Vision but LG's version of it. It's not a perfect algorithm/function though. At times, it will interpet scenes differently than what it should be displayed. Like it might be too bright scenes or too dark. This is where the Panasonic Optimizer comes in and helps the LG TV out to display the content correctly. Again, Dynamic Tone Mapping is not perfect, but it is almost as good as what Dolby Vision would be.

To me, Dynamic Tone Mapping in the LG C9 and CX makes movies look like they should be. Scenes in the day look like they are shot in the day. Scenes at night look like they were shot at night. With Dynamic Tone Mapping "Off", scenes shot during the day look dim and rather lifeless. Dynamic Tone Mapping makes movies come to life. Now for LG OLEDs older than the C9, the Dynamic Tone Mapping isn't that great.

This is just a guess on your part. Without any evidence what so ever. Comments like this can only be made with measurements. If you had you tv professionally calibrated, and if the calibrator knew what he was doing, the dynamic tone mapping would be off. If it was calibrated correctly, and with dtm turned on, it would throw off the calibration. If it looks bad with it off, either your preference override the reference or the calibrator didn't know what he was doing.

You do not need dynamic tone mapping for your hdr10, if it's calibrated your hdr10 would look great on a lg oled. As most movies are mastered at 1000 nits. For movies that are over 1000 nits, the 820 with the optimizer can help. Both my HDR10 and dv are calibrated and they look very similar. I have disable dv on my c8 and don't miss dv at all. One reason why was that my dv in my c8 crushes black slightly on dv.

It was Off when I got the TV. The reason why people have it off is because it is flawed in certain instances. The Panasonic Optimizer corrects those flaws because I also have that set to "On" at the same time. I have tested multiple movies and came to this conclusion. It's still not 100% perfect, but it does a great job overall. It doesn't make sense why playing a movie, like from Disney, is a lot dimmer with Dynamic Tone Mapping "Off" than say the blu-ray counterpart or even the Disney + Dolby Vision Counterpart. Withe it "On", it's on par or better than the Disney + Dolby Vision stream and way better than the blu-ray.

To add, I got it calibrated from Value Electronics, so yes they know what they are doing when it comes to calibrating. The image doesn't look bad, just too dim. Day scenes look too dim but with Dynamic Tone Mapping "On," Day scenes look like they were shot during the day.

I feel like you are basing a lot what you know about Dynamic Tone Mapping by your experiences with your C8. But your C8's Dynamic Tone Mapping is not as good or great as the C9 or CX. The only complaints people say about the Dynamic Tone Mapping is that the contrast/brightness gets too bright on higher HDR Graded Content. That's where my Optimizer Comes in and remedies that problem. I have it set at "Super High Luminance." which allows the TV tone map till 1,500 nits than the player takes over after that.

It might be the master of certain movie that is flawed i would assume. Being calibrated by value electronics, I can guess that with dtm off it is more accurate. Nothing wrong with preferring a brighter picture. Hdr is more for veiwing in dim lit rooms. View the same movie in a pitch black or dimly lit room and reevaluate those movies again. Most hdr movies are mastered dimmer than regular Blu-rays.

It's mostly Disney Movies that have that issue but I have seen others as well. As said, HDR 10 is static metadata, meaning the contrast and brightness is set at 1 level for the whole movie, hence the dimmer picture on HDR 10 movies. Dynamic Tone Mapping takes that metadata and converts it to dynamic metadata and changes the contrast scene by scene based on the content on the screen. It's essentially Dolby Vision, just not perfect. I have done match ups between Dolby Vision versions of films vs HDR 10 with Dynamic Tone Mapping "On" and they are virtually identical give or take a few scenes here or there.

I know exactly what hdr10, DV, and dtm is so you don't have to elaborate. Hdr10 on a calibrated oled does not look dim at all. As long as your eotf is right on hdr then the picture should look the way it should. Eotf is a standard for hdr.

I'll end it like this. As long as you're happy with your settings then it's all good. I'm surely happy with my calibrated, dtm turn off, on regular old hrd10 I'm all about reference over preference. You sound like the complete opposite, which is fine. I'm out.
