But sometimes they do use the L2 trims to raise the brightness. The latest Mission Impossible flick is a good example.

So if I do want DV, Apple TV is a better choice than other players?
L2 trims typically are 100nits, 600nits, 1000nits. Does DV actually use L2 trims at all for 2000nits TV (assuming it will use 1000nits)?

whats the C2 mod???
I did not root my TV to enable DTS support if that is what you are referring to.
Yes, this one https://github.com/RootMyTV/RootMyTV.gi ... 1347543431

I just installed Kodi in Developer Mode and DV works just fine... and I'm out of the return period for my Zidoo too... damn it! :lol:

LE: And it also plays DV with DTS tracks and PGS subs just fine... This was everything I wanted, albeit, not a big fan of the Kodi interface, but could've saved myself $200 also, spent on the Z9X Pro :mrgreen:

I'm not sure. When I force LLDV, they certainly don't work with a 1000nits edid + 1000 nits rpu but when I use the A95 1600nits TV-LED edid, they work but the image looks a bit strange.
Since the colorist can use the trims to raise brightness, it would make sense to always use them regardless of the display edid.

but yeah, the best you can do is to use a TV-LED device (atv shield or sony/oppo).

Seems I rejoiced too soon. Having issues with audio sync, even with non-DTS audio. Any tips on that? I don't use an AVR currently, I use a stereo system through optical connection. No issues with other sources.

no idea...

But on my end(non-rooted), I tried a 5.1 dts-hd channel test file and it's definitely only pcm 2.0 channels :(

Enabled pass-through and seems the issue is fixed for non-DTS tracks.

Does TrueHD Atmos break kodi on your end?
any lossless 7.1 audio(DTS-X/DTSHD/FLAC/PCM ) seem to cause the same issue for me.

No other issues on my end. Only issue is with DTS tracks sync and the endless Kodi scrapping, lol.

...And the FFMPEG EAC3 1536kbps tracks stutter just like on my x800 :( 7.1 EAE encoded tracks are fine.
Damn. I thought this was a Plex issue, but it also happens on the x800. I went back and replaced my 1536kbps tracks with 768kbps tracks. Is there a better solution to this?

We can choose either TV or player led through menu settings on Oppo, on ATV there’s no settings. Is there a way to know that TV led is being used ?

Strange, they work fine on PLEX C2 and x700 but not on Kodi and x800m2.
1024kbps work btw and I added an option to specify the bitrate in the next dovi_scripts version.

Well, it's the player always processing the metadata but yes, it should be fine on 2016-2022 LG TVs.

The player should always use TV-LED when the TV supports both.

Thanks & sorry, maybe my Q wasn’t clear. Using what method or test can we check that a player is using TV led, and ditto for the TV (in my case LG 2017 E7 OLED). The reason I ask, is I find the Oppo when set to TV led, there are too many handshakes & in the end I have no clue what is being used: TV or player led.

you can use this test file. Unless you have a C2, L2 Trim Chroma Weight will only work in TV-LED on cmv2.9 players.

Also, I think that if you press 3-4 times on the green or blue button on your remote, it should display if the signal is RGB 8bit (tv-led) or 422 12bits (player led).

That is super helpful, thank you ! I had Oppo set to TV-Led w these tests. Using LG Cinema Picmode, DV cal profile from sonoftumble + 2/20 points settings.

- Testfile: Not sure how to interpret result, need to watch Vincent's video w that eagle/hawk. I do see a clear difference between original & no-trim-chroma-weight. I tried my best to take photos:
slow pics comparison

- Buttons: Pressing 3 or 4 times on either green or blue buttons sadly doesn't do anything. I'll search on the net as this is the first I learn about this.
