Hello. How do I find out if my TV supports CM4.0?

Unless it mentions it in your user manual...

Maybe you might have to do a sample of both, and see what your TV does with it.

If it's reasonably new, I'd say it will support CM4.0.

What brand & model is your TV ??

Hisense U8H (non US version)

I was able to get the specs on this....is it a 75" ??

It doesn't mention anything about that, but I would think that it will be OK with CM4.0, but like I said, try a sample of each, and test for yourself, it won't take long, and you'll know for sure

You can easily create a 5 minute chunk of a movie, and process it both ways.

Good luck.

it's a 65inch. Alright thanks

But you said this, "P5 encoding from scratch requires the proprietary Dolby engine,"

You can with Resolve and the custom edid I gave you.

Hello. How do I find out if my TV supports CM4.0?

All the TVs made after 2019 should support it. You can try the cmv4.0 test files here: https://drive.google.com/drive/u/1/f...rk-Ifx6vRYDEfs

My only serious reason for wanting to try P5 was to see if there was *any* profile that would get 8K DV working in the LG Z3.

Of the files you offered, unfortunately, none worked on the LG and only one would play on his Mac (p8.1.HDR10plus.8K DS_NEW_mp4box).

He did say that a file I created in P8.1 played on the Z3 in HDR10. My assumption prior to that was that standalone HDR10 would be playable anyway, but perhaps not. Does the LG need HDR10 to be the base layer in a DV profile to play?

Edit: It's an LG Z2, not 3,

[Kuler087]

unfortunately, none worked on the LG

I'm surprised that even the files encoded/muxed in Davinci Resolve didn't work.

Just not 8K files. Seems to be a failing of the tv, not your files. Played nicely in 8K HDR10+ on mine.

P5 files obviously don't play on Samsung.

I've been doing a bit of "research", and there must be a fairly simple explanation why nobody can get 8K DV to work (yet) on LG Z2 (3), I wonder if it needs different settings ???

We know that dvhe.08.12 works in 4K, and that 8K did not, even after lowering 8K bitrate to 30 Mbps, except HDR10 it did. If you have a 8.4 profile to try in 8K, we will. My theory has been tv is not supporting 8K DV in any flavor.

I looked up the spec's on the Z2, and it states that Dolby Vision IS supported, but that's ALL it says

Not sure how to create an 8.4, that's something that Kuler would have to comment on.

You might be able to do something with Resolve, and inject the DV metadata into "something"

I downloaded an 8K clip off YouTube earlier today, but it was encoded with AV1, as an mp4, but of course I don't have an 8K LG TV.

YouTube DV AV1 (nor VP9) is not playing in DV on his Z2 nor my Hisense U8. That's in 4K of course. You found one that does? Would like to have the link to try.

Have you searched for 8K DV clips on YouTube from your (your friends) TV's to see how they play ??

Here's a link to something that may help:-

We haven't found any clips streamed in DV by YouTube. They play fine in regular HDR10 and even 8K. By DV I mean it's got to turn on the Dolby Vision icon on the tv set, not just whatever badge the YouTuber sticks on his video saying Dolby Vision. I think there is confusion with people seeing a DV badge added by the uploader versus actually turning on the tv's own icon or indicator light, whatever. My understanding remains that YouTube does not stream DV. I will try your link though.

I agree, you've gotta see that Dolby Vision icon on the tv set, that's for sure.

That link played in 8K but not even HDR10, never mind DV.

I found one here that plays in 8K HDR10 on my Samsung.

I have to go in the other room where my U8 is to see if it plays in actual DV (in 4K). Will report back.

That clip was only available (to download & play) in 2160p/4K @ 60fps, you need at least 4320p/8K @ whatever fps !!!

Did it actually display @ 8K ??

here's another:- choose to play it in 4320p !!!

Yes, it streamed in 7680 x 4320 @ 60fps AV1 smpte2084/bt2020
...but not Dolby Vision.

120 fps is just the camera frame rate it was shot at, slowed to 60 in post. YouTube doesn't stream higher than 60, at least not at 8K. And there's no tv that supports native 8K 120 playback either.

I don't know about downloading from YouTube, never tried, just streaming.
