I know there's some displays out there that will take a higher quality signal such as 4:4:4, downcovert it to 4:2:2 then upconvert it again.

I learned that from one of Vincent's videos (I think) and there's a disc with a test pattern that helps you select the correct output for the display you have. If it gets downcoverted then upsampled again, the quality ends up being worse.

Maybe it's like that with older TVs? I don't know, but it seems to me if you send a 4:4:4 video to a modern 4K HDR TV, it should except that signal and run with it.

By selecting and forcing YCbCr 4:4:4 I get a dynamic conversion mode which sends out SDR BT.709 8 bit during HDR playback.

Cable and TV settings are fine. The Auto or 4:2:2 sends out the correct HDR BT.2020 4:2:2 12 bit signal the player is sending.

I use 4:2:2 for the reason below.

just set it up--- for some reason when I check the playback info on the Panny-- it now shows zero info on the HDMI out...?

it shows 1000 nits on the media part but nothing in the HDMI out info... is this because I have it set to OLED instead of high luminance?

EDIT-- just switched to Super High Luminance and no difference-- is this because of Dolby Vision? I notice I can't change my tone mapping with Dolby Vision...

Sony TVs only display full 4:4:4 in game/graphics picture modes. In their other modes, they roll it off.

Panasonic players, when outputting 4:2:2 require 12bit upsampling for some reason.

Personally I use 4:4:4 10bit output and keep my TV in Graphics mode

Yes! When playing Dolby Vision content, it does not display the outputted information through your HDMI Out. Only when you play HDR10 content will it display this information.

In addition to Josh's comment, the HDR Optimizer is ignored when watching Dolby Vision.

Graphics mode really does look nice ..once you get used to full chroma it's hard to go back I'm happy to give up most of the superfluous processing, but being able to toggle motionflow to 1 if I know there's going to be some panning scenes would be nice. That's probably the only thing

That's...weird. If it's forcing the SDR conversion then something is blocked in your signal chain from accepting 12-bit 4:4:4, this is why the player is doing a conversion.

I gotta aks: have you made sure that the HDMIs on your TV are set to Enhanced and not Standard? Because 4K24 12-bit 4:2:2 is capable of being handled by the HDMIs set to Standard (as per the 300MHz limit of HDMI 1.4), but the same signal type in 4:4:4 is too much.

Thank you Geoff. That's exactly what it was.

I know this is the wrong thread but I've had a couple other questions here regarding my new OLED 77" and Panasonic 820.

Everything is working great but I'm having an issue that I don't understand.

I have my cable box and player running into my receiver and from there to the TV on HDMI ARC 2.

I get sound from my player and sound from cable.

I just hit the Netflix button on my LG remote and while I get a picture-- the volume I'm getting is from cable............... no volume at all from the Netflix app... any ideas?

Hah! No worries. Easy to not check it though when everything seems to work fine otherwise, but I don't know why they don't just enable them as Enhanced on factory settings.

Which device is running the Netflix app? The TV? Does your TV have ARC enabled? Is your TV connected to the HDMI ARC compatible out on the AVR? I’m assuming you’re not getting audio from the AVR when you’re using the Netflix TV app.

I also read you need a HDMI cable with Ethernet for this feature to work. Essentially you need a cable that has a return data channel to get the audio signal from the TV to the AVR. If you use optical you are limited to lossy codecs but streaming services only use lossy codecs for audio other than some music services.

If I’m not mistaken, you will need to press the settings button and change the audio output to HDMI EARC on the TV. Then that should work with all the apps on your TV. If that doesn’t work, just use an optical cable going from your TV to your receiver. It might not be lossless audio, but you will still hear it.

I have the ARC setting right... I'm just gonna leave it for now--- I have enough work to do getting my cable and Panasonic settings right!!!

I'm thinking I will have to run output from the TV to the receiver to make the apps have sound...

I'm not 100% on Dolby Vision yet--- I don't like the fact that I can't make adjustments on tone mapping in that mode--- but the one movie I checked (Casino Royale 4k) looked pretty great!! I also checked a non Dolby Vision 4k movie (Backdraft) and it looked spectacular too!!!

Isn't the HDR optimizer only relevant when watching HDR content? I thought it did nothing when using DV.

No need to run an additional cable. You just need to make sure your receiver is set to the "TV Audio" input (or something similar). So long as you're using the correct input on the tv (labelled arc or earc) you'll get audio from your TV through your receiver. The video will play on/from your TV and the audio signal will run through the arc/earc input on your tv to the output on your receiver.

Unless I'm missing something, that only seems to be an advantage if you're watching 4K/60fps content. Since 99% of the movies out there are recorded and played back at 24fps to me it's not something to worry about.

Funny, that reminds me when the dollar coin was introduced in the United States and vending manufacturers (while making vending machines that could accept dollar coins) did not bother flipping (or turning on the option) inside the machine to accept dollar coins!

What's seems weird in my case, I know for a fact that i had all my HDMI's set to Enhanced. Then when i switched the color mode to 4:4:4, it went back to standard. Maybe it's normal when switching color modes, i don't know. But, thanks to your post, I checked and got it back to enhanced.
