@RESET_9999 have you been able to test the color saturation/accuracy on the 23AFTVS4KM?
I noticed some extra saturation compared to other devices. I might not investigate this any further since I don't really care about a device that cannot do tv-led. Also, the Firestick devices are doing some Dolby Vision IQ internally even when your TV DV IQ is disabled. If you take quietvoid's L11 test file, it is supposed to work only when your TV(LG) is in Cinema Home mode with DV iq enabled.
For DV MKV playback, I've been using my C2 internal player lately. It seems stable and it works very well, at least for the 3 movies I watched so far.
You have to sideload Kodi in developer mode but it's not too complicated to do and its pretty nice to finally have DV MKV support on LG TVs.

I dont know if there is a free way of getting your TV edid info. I use the vertex and I can also get the edid with a cheap raspberry pi and PGenerator:

If the edid is higher than 1000 nits, what to do with homatics, ugoos, zidoo, firestick, dune, etc boxes? Trow away in garbage? Or use it only for non DV formats?
if the RPU is 4000nits it's fine but if the RPU is 1000nits like the majority of the movies, do not use DV on those devices.
As I understand only Sony x700 and X800m2, Oppo 2003 and ATV latest generation can do real TV led. Am I wrong?
Yes, all the bluray players should support TV-LED and AFAIK for the media player, only the shield and ATV support it.
How I know a movie RPU nits trough your scripts?

Happy New Year.
Just to clarify when I use the DoVi scripts to plot a UHD disc with Profile 7 FEL the graph is using all the Profile 7 FEL layer metadata?

Yes, the values in the plot are for the BL+EL decoded brightness.

Zidoo can save TV edid. Zidoo can set customised edid. If my TV is 2000nits and I set Zidoo edid to 1000nits, would it work?
With a 2000nits TV, you don't need DV for 1000nits movies(and for most of the movies). A 1000nits edid would be a bad idea because then any shot over 1000nits would be tonemapped to 1000nits while your tv is capable of displaying it untouched. HDR content is graded brighter than the MDL sometimes.
Do you mean I should just watch HDR layer instead of DV for the same content? Do I lose anything that DV provides?
I guess what I am trying do is to find a decent external player for P8 cropped content. P8(full frame) can be watched with x800m2. Another way I can think of is to remove cmv4 and use Apple TV. That should give me true TV-led?

Yes, if the content is within your display capabilities, DV doesn't have to tonemap/compress highlights/gamut.
But sometimes they do use the L2 trims to raise the brightness. The latest Mission Impossible flick is a good example.

Wait wait wait, if I install Kodi through that method, I get DV MKV support on my C2 through the built-in player? Can this tool also be used to enable the limited DTS support? I know there was an option to do so with a command line.

yep, finally!!

I'm not sure, I have to test this again but I think DTS and PGS subs are working (probably sent in pcm??)
TrueHD doesn't work and it breaks the app on my end. I have to restart the TV if I want Kodi to work again.

Does it break TrueHD support or something through this method or is a Kodi thing? As I don't remember having issues with Atmos tracks on my C2 or does it actually drop to the core track although it says it plays the Atmos track?

only on Kodi but I have more tests to do. In my initial test, playing a file with Truehd triggered DV but no sounds and the video froze at some point. Then any other file will freeze too unless you restart the TV.
You cannot even use the exit button in Kodi, it freezes the app(not the TV) but you can use the remote and go back to any other app.
This is using the Plex addon to access my library though, I haven't tried to access my PC directly without plex server, maybe it will behave differently.

Got it. Will give it a go later today. Mine is not even rooted yet. Many thanks!

yea, i tried again and DTSHD is working on my end (kodi set to best match). My AVR reports PCM multi-channels and plex EC3.
This is much better than plex where it fallback to HDR10 when input has DTS.

Is this with the DTS enabling on the C2 mod?
Also, from the screenshot it seems it drops to EAC3, it does not play DTS.

I did not root my TV to enable DTS support if that is what you are referring to.

as I said, my AVR reports PCM multi-channels and plex EC3
But I suspect I'm only getting 2.0 channels PCM because the C2 doesn't support 5.1 pcm.
