Dolby Vision now possible through MP4 Mux.

I also have access to a CX, C1, and C3.

I'd be curious to know if L2 trim Chroma Weight work on the C3. It doesn't on the C2 internal player or TV-LED hdmi.

PS, using the C2 edid on my cheap Vizio TV + x700/x800, Chroma Weight is working so no reason to not work on the C2.

x700 doesnt support cmv4.0 so it doesnt matter

Regarding CMv4.0 and CMv2.9 discussion, there are player devices and display devices in TV-led DV mode.
Does a CMv2.9 player care if the metadata is CMv4.0 or CMv2.9?
If player is CMv4.0 but TV is CMv2.9, does the player send over full CMv4.0 data (both L2 and L8) or the player does some processing only send L8 data? If full CMv4.0 data is sent, TV should use L2 data?

Thank you in advance!

[RESET_9999]

In order to display CMV4.0 videos, both the TV and the player must support it.

If the player is cmv2.9, it doesn't matter if the content is 4.0 and the player only uses the cmv2.9 block
if the player is cmv4.0 but the TV is not , only the 2.9 block is used unless the player is in LLDV mode.

Yeah feels like we need a completely new thread with more organized instructions. Do we even consistently get better image with dolby vision compared to hdr10 at this point? I honestly have no idea.

If you're using an LG or Panasonic TV with a color-accurate TV-led player, the answer should always be yes, as long as the metadata used was intended for what is being played.

If you use a Sony A95K, you're better off with Dolby Vision. I'm guessing the A95L will also be in this situation once Sony fixes its Dolby Vision EOTF tracking (it currently requires Gradation Preferred for accuracy, which sounds like it uses Sony's Tone Mapping instead of Dolby Vision).

If you're using pretty much any Sony TV other than the A95K that is TV-led capable, then most have issues with their Dolby Vision base configuration data. Unless you can measure your specific panel or see measurements from someone else who has measured, you may be better off using HDR10 with Sony's Gradataion Preferred tone mapping.

If you're using any Sony TV that is only Player-led capable, it also depends on your playback device (many playback devices aren't up to the task from RESET's research). If your Sony TV is only Player-led capable, it likely has less luminance and color volume and can significantly benefit from Dolby Vision's tone mapping. Still, I'd measure it regardless since Sony has a history of striking out with Dolby Vision.

If you're using any other TV brand, there isn't enough data to determine what's best. I'm unaware of anyone doing deep analysis on Hisense, Vizio, TCL, and Philips TVs since most enthusiasts are on LG, Sony, and Panasonic TVs.

one thing is for sure, if your TV has an edid higher than 1000nits (majority of the TVs nowadays), don't use the cmv2.9 devices that cannot do true TV-LED (zidoo, dune, ugoos, homatics etc..), they are completely broken.

and the fact that the zidoo and vertex guys recommend using 1000nits edid for LLDV in HDR10 playback is hilarious.

[ragico]

How can I know the edid of my TV?
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?
As I understand only Sony x700 and X800m2, Oppo 2003 and ATV latest generation can do real TV led. Am I wrong?

[RESET_9999]

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: https://www.avsforum.com/threads/dedica ... 5/#replies

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.

Yes, all the bluray players should support TV-LED and AFAIK for the media player, only the shield and ATV support it.

homatics etc..), they are completely broken.

Is the Homatics Box R 4K Plus definitely one of these that is completely broken when the MDL >1000-nits?
If not, which Homatics device are you referring to?
Asking because I thought the Homatics S905X4-K devices were CMv4 devices.

[RESET_9999]

I'm referring to whatever model @dmdreview tested in his video. You can ask him, I don't have this device.

I looked closer and he says in the video description (not in the video itself) that it is the Homatics Box R 4K Plus. That's the latest Amlogic S905X4-K that's being used in all the current SEI804HM devices (Homatics, Dune, Nokia, Rocktek).

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?

If you want a Player-led device then I think you'd just be significantly better off picking up a 23AFTVS4KM (2023 Amazon Fire TV Stick 4K Max) and loading Kodi on it. You also even run PKC (PlexKodiConnect) on it. That'll give you Atmos TrueHD passthrough with the most accurate Player-led luminance RESET has tested.

@RESET_9999 have you been able to test the color saturation/accuracy on the 23AFTVS4KM?

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.
