Dolby Vision now possible through MP4 Mux.

ok, I'm starting to understand what's going on with the different RPU responses on players in TV-LED and in LLDV. It seems the x700/x800m2 almost completely ignores L1 and always tone map to the TV edid target.

Yes, oppo and all bluray UHD players change the PRU in TV-LED mode. they change the data from the RPU and then it goes to the TV.
Shield tv does not touch the PRU.
I will show in a video soon how it looks like in the video data from the RPU.

It would be nice to decode back from the binary code of the RPU video to see what changes there specifically. But I don't know how to do that

does this mean bluray UHD players should also be categorized as 'fake TV-led'?

Yes, I am the author. ...

Is the EDID info shown using the TV itself or some other method (Pgenerator on rpi mentioned by RESET) ?

No, the TV still does the processing, but UHD players give it some hints based on EDID data from the TV itself.

I don't quite understand what you mean. But as far as I know you can read EDID with the utility https://entechtaiwan.com/util/moninfo.shtm.
Although I haven't tried it myself.

Thanks I'll check out that tool. At 1'39" of your video, there's a black info overlay but now that I look at it, it seems maybe from your capture card (would you mind sharing which card ?). I thought it showed EDID but actually has lots of video signal properties.

Now understood. this very good site with edid decoder https://hverkuil.home.xs4all.nl/edid-de ... ecode.html

That's also helpful but not what I am asking about. I was asking how did you get EDID info from your TV. I thought wrongly that signal info showed it in your video. RESET_9999 explained few pages ago & I wondered if you were using the raspberry pi/Pgenerator. We can for now "forget about it" : )

PS: That moninfo tool didn't show anything useful (EDID) when I connected my Bootcamp/Mac to my LGTV via HDMI.

Try to download your edid with CRU:

That's so funny, I just finished doing that but didn't find anything useful related to DV or HDR... I think it seems CRU depends on the GPU on the laptop (MacBook Pro 2018 i7, Intel Iris Plus Graphics 655) or the USB-C to HDMI Anker adapter , but unsure ! Grrr can't attach .txt ... or is it a quota issue.

Here's a LINK to that text file decoded from the site that @DMDreview shared.

What is the size of the original EDID file, it feels like it is without the second 128 bytes. the size of the full EDID is 256 bytes.

That is what I exported from CRU & decoded by that site, idk what you mean by original file unless the .bin file which is also 128bytes.

full edid BIN =256 bytes. You need read full EDID with extended data

[RESET_9999]

yes, I just tested with my C2 and if the display connected to the PC is not a certified DV monitor, the DV bloc is missing from CRU edid. A TV is not a certified DV monitor.

[aboulfad]

^^^ Understood, though CRU has these following limitations & my MBP 2018 has most likely a dum & unsupported GPU. Oh RESET just discovered the mystery

Extension blocks:
GPU-specific limtations:
CRU can read extension blocks from displays connected to AMD and NVIDIA GPUs.
CRU can't read extension blocks with Intel GPUs or switchable graphics.
Older drivers or GPUs may only support up to 3 extension blocks.
