@PaulGo, cjake answer this very well. Thanks cjake.

Panasonic's HDR Optimized has a set-up menu where you can select your TV or projectors peak luminance ability. Once you properly set the HDR Optimizer it will follow the PQ curve as far as possible to your display's peak lumens and gently roll off the brightest image areas without clipping.

So do have to go into settings and manually set peak luminance for my projector 2200 lumens or will the optimizer do it automatically once I pick low luminance projector setting.

For your application once you select projector you are all set.

On my last update I was told early fall.

There is only one OLED setting, which tone maps the output to 1,000nits. All OLED TVs can properly handle a 1,000nit peak luminance image.

It is Saturday afternoon and I just placed an order and received PAYPAL receipt. Will this be filled from the first shipment?

[Robert Zohn]

Yes.

Robert then I go back to my original question - Why don't expensive HDR10 TVs has this circuity built in? It would seem in the design of the TV as long as the video processor is capable it would not really add much if anything to the cost.

[Robert Zohn]

Very good question that I don't know the answer to. Maybe it's just the genius of Panasonic video engineers that came up with the idea of the HDR Optimizer.

How many Firmware updates have you had since receiving the UB9000?

[Robert Zohn]

Just one, version 1.12

I'm from Germany and got my 824 a few days ago. So far I'm very happy with it. I had the 424 before and after having the 824 now I will never ever go back to a player that doesn't have a display in the front. That might not be a big issue to some people but that alone was worth the purchase for me.
As for the HDR Optimizer. My TV is a Samsung 65KS8090 (I believe the US Version of that is the KS9000) and with the movies I watched so far I can't really see a big difference (or any at all) between having the Optimizier on or off. That probably doesn't mean much, as I don't really know what I'm looking for anyway to be completely honest... The only movie I rewatched that I also watched with the 424 was "The Greatest Showman". And that movie looked absolutly stunning on both players. I guess I could change the setting from "Middle of High Luminance LCD" to "Super High Luminanance LCD". But I'm not sure what Panasonic means with "Super High".
I'm also wondering about the "High Clarity"-Sound option that seems to be active by default. Does it make sense to keep that on? I'm using the primary HMDI-Out of the 824 to connect it to my TV and the secondary HDMI-Out to my AV-Receiver. Isn't the High Clarity thing only something that comes into play when using the analog outs?
The latest firmware for the 824 is 1.12 btw.

This way my LG will not see 2049 as a 10000 Nit title but a 1000 Nit title and the LG tone mapping will be much improved.

I would like to wait for the 9000 to be released in the US, but I will likely get an 820 instead.

I think that's exactly what the Optimiser does, retrofitting more appropriate mastering monitor metadata to the signal, otherwise it'll play havoc with its custom tone mapping if the target display then applies, say, a 10K nit mapping on top, like that on your example of the US version of BR2049 (which I still think has faulty metadata in general, the primaries being listed as 2020 is another red flag for me).

Using the mastering display metadata to map to is an inherently flawed proposition (as Kris says, it simply doesn't need to be there) so I'm glad people are finally able to get around LG's cack handed approach with either forced DV or the HDR Optimser.

Curious how different the 820 HDR optimizer tone mapping of HDR10 material is from the Oppo 203 when you force it to apply DV to HDR10 material. I have a 2016 E6 OLED and as of right now, I have my 203 convert HDR10 to DV, which produces a better picture.

[Geoff D]

I'd love it if someone could measure how the PQ curve is actually tracking with the Optimiser, yeah. When I clocked what the forced DV was doing on my ZD9 it produced one of the most accurate PQ curves I've ever seen (albeit hard clipped to 1000 nits) and that's kinda the point why it works so well on some TVs: it's not that it's applying dynamic metadata to something that doesn't have it, it's not that it's specifically mapping each bit of content according to the static mastering/MaxCLL metadata therein, all it's doing IMO is applying a competent tone map and doing it within a 12-bit space that bypasses the shitty processing inherent to whatever brand of TV.

Look forward to reading Kris Deering's UB820 write-up.

Too bad you live on the other side.

You would have been most welcome here measuring and calibrating my TVs and PJ all you'd like.

So the oppo 203 can force dv?!

Yes it can do force DV as one setting for HDR10 or even SDR content, and play all media in correct playback in AUTO. If you have a UDTV you also have a force HDR10 mode where you can disable the DV engine entirely until you change a setting and power cycle.

[flipsyde2000]

Got mine pre-ordered through Value Electronics can't wait to get it!!!

When I had my oppo 203, my tv was the LG 65ef9500 which doesn't have dv. Therefore I never looked into that option. I recently sold my oppo 203 in anticipation of getting the Panasonic ub820. I also recently upgraded to the OLED65C8P. Now I wonder which is better, force dv or hdr optimizer. I have very high expectations for Panasonic. My guess is that Panasonic will be better but who knows for sure....yet

[E6AtmosVuduDV]

Is Forced DV at director's intent, accuracy for Dolby Vision movies?
