I compared the mp4 played with my Shield RGB bt2020 and with in-app Philips
Shield Normal VS Philips TV https://screenshotcomparison.com/comparison/4946

And my results seems slightly differents
Cyan is brighter with my shield but i'm not sure about a red push
it's very strange

interesting..... yours appear undersaturated compared to the philips and yes indeed, very different than my comparisons but I noticed your taking pictures in a bright room. My pictures were taken in a complete dark room ( black velvet everywhere) without any light. Perhaps thats the difference ? I dont know but I'm clearly getting the same color difference no matter how many comparisons i do.
Also, I assume your camera settings are locked?

It's not in a bright room, just ambilight activated. I could try to turn off ambilight.
And yes I locked my camera Settings (ISO, Shutter Speed, Aperture, White Balance)
I will also try later today or tomorrow the video with plex running on Philips to see if the problem come from Multimedia App or Shield TV

I can't tell there is any noticeable red push
Bravia internal Plex vs Shield Plex
Bravia's internal apps are brighter, so ignore brightness difference

do you have any device that can tell you if you are getting RGB 8bit DV or LLDV 12bit?

yeah, with a Sony TV, you shouldn't have any red push with genuine profile 5 files or from any streaming apps.
but thats a huge brightness difference!!

My TV tells me that I receive 8bit RGB when using Nvidia Shield

Interesting. is it an OLED ? I wonder if that could matter.

Finally

I can see clearly the problem with DV and Bravia Tvs

With DV through HDMI is more darkness than trough apps

What model have you?

I can't understand why Sony don't fix the problem

RESET_9999 wrote: Tue Jul 28, 2020 7:34 pm Interesting. is it an OLED ? I wonder if that could matter.

Yes it's the OLED934 model
It's pretty strange

In the shield setup I have YCbCr 4:2:2 BT2020 DV Ready
When I read :
- DV Files my TV displays DV 8bit RVB
- HDR10 Files my TV displays HDR BT2020 8bit

but if I setup to YCbCr 4:2:0 BT2020 without DV
HDR10 Files my TV displays HDR BT2020 10bit


But I can only have info if source is from HDMI, so I have no clue about info while playing HDR10 or DV Files with InApp Philips

8Bit RGB is normal for DV if your TV supports it, which looks like it does. Are you not also seeing the BT2020 tag next to 8Bit RGB when playing DV off the Shield?

Yes I did not specify but it's BT2020

I meant to mention this before but just an FYI, when playing these discs on my UB820, it is also showing RGB 8 bit BT.2020. And yet it has the correct color space.

Now I'm confused...
you once said on avsforum that you were getting LLDV out of the UB820. are you sure your Integral scaler wasn't set to RGB bt2020 ? would also explain why you didn't see a difference on the Spears demo.
https://www.avsforum.com/forum/39-netwo ... st59652754

what's the default DV mode on the UB820 when the TV is capable of both format ?

SamuriHL wrote: Tue Jul 28, 2020 3:53 pm That's really bizarre. That's completely different than the results I saw. I'm not able to take screen shots to show it, but, the picture was identical on the SM benchmark demo between my UB820 and the Shield. And I was not using the Integral 2 to correct anything at that time. And yes, I do get the red push problem in other videos. That Doctor Sleep sample that shawnc22 posted, as an example, I compared with my LG internal player vs the Shield and definitely saw the problem. So I have no idea what the pattern is here.

The difference can be hard to see but if you compare a scene with a lot of red colors, it's more obvious.
like frame 5066

I just used that scene to compare close up and I'm not able to see it. Which isn't to suggest it's not there, simply that I'm able to see it. I don't have the camera equipment necessary to make even decent comparison pictures, so, I don't think I'm going to be a whole lot of help on this one. I'm of the opinion, that *for me*, if I'm unable to see it up close and personal in a frozen picture while flipping back and forth then in real world content that's movie I'm unlikely to notice the difference in most cases. Now the Doctor Sleep example is night and day for me and I can clearly see the issue there. Clearly I would like this issue corrected, regardless of whether I can detect it in real world content or not. The point of DV is to present the best possible picture quality and I want it to be as technically accurate as possible. Right now I don't trust the SHIELD with these UHD rips. Even if I can't materially see a difference, it's still bothersome. Especially given that I've only just begun to compare samples. While the SM benchmark UHD is a gold standard, it's not super indicative of real world content. It's more designed as a torture test for your playback chain.

I was mistaken about that. It's always sending RGB 8 bit BT2020 for UHD discs. At least on my C8.

Did you compare your Shield with the C8 internal player? Because my x700(RGB no bt2020) is identical to my C8 internal player and using the vertex, the shield is identical to my x700.

internal C8 vs x700 RGB no bt2020
