Should I just let my tv do the upscaling then?

Is the OLED TV just better at tone mapping where the setting is basically doing nothing at all? I mean I was pixel peeping with it both off and on and see not even a slight difference.

Also. for the Luminance setting. Should I go Medium/High or Super High? I believe my TV tops out at around 1200 which is higher than the Medium/High setting but below the Super High setting.

You've sort of answered your own question with regards to the HDR Optimizer. If your TV is capable of >1000 nits it won't be doing anything.

OLEDs have been getting progressively brighter, albeit still far inferior to LED sets in that regard. My now 4 year old Phillips only maxes out at around 750.

Which is more than enough for decent HDR, as long as you don't watch it in a bright room (why would anyone do this btw?)

Does the 820 do 24p for DVD and do you use it? (I haven't checked). I had a revelation recently on my old Toshiba HD-XA2, that many discs look better with 24p output, movies mostly, but it reigns hell on the image if it's a real 60i image, easily seen on most menus especially. One set I found this out was watching the old Clerks cartoon. I also found some discs I swear must be progressive scan native because if you try and output them interlaced the picture has bad screen door effect, but in progressive mode it's smooth as butter.

[TooOldToDieYoung]

Don't think the 820 can do that, unfortunately. My old BDT700 does, though.

I don’t think the Panasonic let’s you do that.
This would really annoy me. How bad is the added sharpness on BDs?
I am certain that my Oppo when that day comes, but this would irk me.

You're a lifesaver! I currently have a Hisense U8H, which boasts a peak brightness of 1500 nits. I was really tempted to buy the Panasonic 820 for its HDR optimizer, but I think I'm going to go with the more affordable 450 instead.

- Does the 450 play 3D blu-ray discs?

Yes.

Edit: I believe that the only UHD players that don't do 3D are the PS5 and XSX.

Never did it but I'll try it today with a Koch Media B-locked disc.

That may be true, but even the most adept videophiles would probably have a hard time discerning any PQ differences in a blind test. The 450 is perhaps the most decent basic player there is.

[ronand]

The 450 supports the top menu trick. It doesn't support changing the remote code - it's on code 1. But if you can change your other players then that shouldn't be a problem

[Foxwing59]

What's this about a remote code trick?

AFAIK the Panny can only output one resolution at a time. You really want to switch back and forth so your TV can upscale 1080p content? That sounds like fun. Might as well use an actual 1080p player for Blu rays.

Anybody experienced settings for perfect match beetween LG CX and UB9000 ?

I dont understand if it is ok to use DTM LG/UB9000 optimizer ON for HDR
Settings for Dolby Vision which is too bright/artificial with Dolby Vision Cinema e too dark with Cinema

[bl4ck]

HDR optimizer settings have nothing to do with DV.

[Telemachus]

You don't need to change DV settings period

Maybe leave it on Dolby Vision bright, but turn down the TV backlight to suit?

You can still have playback issues with it but I see more UB820 complaints than UB9000. I have not tried an optical drive swap from UB820 to UB9000. not sure if it will work. I know the UB900 optical drive works in the UB820.

Gidday danny24,

if you are interested in comparison drives between UB820 and UB9000 with pics and here is a small write up by me : https://forum.blu-ray.com/showpost.p...ostcount=15125

Also there is an extra integrated circuit chip on the PCB of the UB9000 and is not on the UB820 PCB and so I personally would not take a chance by putting it on the UB9000. Perhaps on boot up it would detect the drive but no function.

And yes the UB9000 drive in the UB820 is nice and quieter and heftier than the UB820 drive. Cheers!

Thanks for that. Yeah I figured it would not work.

It depends on several factors here. But first, here is how the Optimizer Works:

The Luminance TV Type setting determines the nit value on where the HDR Optimizer will start working

The Basic/Low LED is set at 500 nits. So, the Optimizer will tone map anything that is graded above 500 nits

OLED as well as Medium is set at 1,000 nits. So anything that's graded above 1,000 nits will be tone mapped.

Super High Luminance is set at 1,500 nits. So anything above 1,500 will be tone mapped by the Optimizer

I would suggest switching between the OLED setting and Super High Luminance to see which one is better.

Now the 2nd factor is the content being played. Some content will be graded lower or the same as the OLED Setting (1,000 nits). That means it won't do anything to the picture. You need to pick something that will change when using the Optimizer. I would suggest a movie that has a MAXLL of 1,500 nits or more. Or find a movie that had a mastering monitor of at least 4,000 nits.

Some good examples: Hook, any of the Harry Potter films, some Marvel films. Once you find a good setting, keep it there.

I have compared the sounds of my DP-UB9000 and a DP-UB820 I ran across at a Magnolia inside a Best Buy. They both use the exact same drive. The only difference is the DP-UB9000 one has a metal plate on top of it and a tray that is made of a different material, but you can clearly see that underneath that metal plate is the same black plastic mold as that which houses the DP-UB820 one. The extra silence of the DP-UB9000 comes from its anti-vibration chassis.
