For eg. I'm watching Mad Max Fury Road. It's mastered in 4000 nits. Nits range for the movie is 3000 to 9000 nits. The HDR optimizer clips it for a 1500 nits tv and optimises the hdr. Therefore the Nit range for the movie will be 1200-1500 nits.

That just means your Samsung TV has really poor tone mapping...

Could be an issue with the 4K optical laser. If your player is still within the warantee window I would reach out to Panasonic ASAP. If not I would at least try a lens cleaner disc first before sending it off for repair.

I have a question. When I’m watching a blu ray that is not 4K should I set the resolution on the UB-820 to 1080p. For example, I’m about to watch The Third Man, the criterion collection blu ray that is 1080p, but when my player is set on auto resolution I believe I will be up converting to 4K

[PissedOffPeoN]

depends if you want to up covert it or not. Auto is fine, since it does a really good job upscalling to 4k.

If the player doesn't upscale then the TV will, assuming that you have a 4K TV as well. Otherwise a 1080p disc would only take up a quarter of the screen. So one way or the other it has to be uprezzed to 4K somewhere in the chain.

Had to recently to a hard reset and ever since my Atmos is no longer working on my receiver. What audio option should I be selecting on the player? Is there an atmos option that Im not seeing? Thanks

Digital audio to Bitstream and turn off Secondary audio?

HDMI out... audio bitstream. Turn off Secondary Audio. Turn off Dynamic Range Control.

Thank you. What about 4K/60p
I have it set 4:4:4 should I turn it off if I’m on 1080p. Thanks for your quick response. I just like to know these things. I’m not big into up convert I like watching what the disc actually is.

[PissedOffPeoN]

then you can just set it to whatever u want it to instead of it upconverting it, but i think upconverting looks great.

Discs store the movie in 4:2:0. Everything needs to be upscaled at some point in the signal chain to 4:2:2 to 4:4:4 to RGB. The Panasonic doesn't do any output other than 4:4:4 or 4:2:2 12bit. Just leave everything on auto and no need to overthink. You can force the panny to output 1080p but then the TV will upscale anyway. You might as well have one device do the full upscale to 444 12bit.

The cleaning disc did not work, but spider man far from home worked.. seems to be the only 4k disc that has worked so far.

When I set the Color Mode to 4:4:4, it converts UHDs to SDR/709 and 4:4:4 8 bit. When I set it to Auto, I get HDR10/2020 4:2:2 12 bit.

Standard SDR blu ray is output 4:4:4 8 bit regardless.

Needless to say, I’ve been keeping it in Auto since I don’t want it converting HDR to SDR.

So Auto is the best setting or is it interacting with another setting?

Keep the 4K/60 setting enabled.

So your cable or your display doesn't have the required bandwidth then.

Finally got the Panasonic 820 coming! So excited ��

[PissedOffPeoN]

I am still confused as to why this players stopped playing 4k discs but blu rays work fine? Is there anyway to contact panasonic about this?
