Dolby Vision now possible through MP4 Mux.

I already explained why literally in the post just above yours.

in this case, why you do only 4000nits rpu's instead of 1000nits?

sorry, i saw it now. is it also necessary for my G4?

Most likely. Although no one has measured the G4, it appears to affect all LG TVs.

You can test it yourself - https://docs.google.com/spreadsheets/d/ ... 1289366200
Just follow the instructions on the right.

@RESET9999 I'd like to ask about your latest video: https://youtu.be/GnVNJkiunJo?si=83R1Bs5SBwYEY8RV
In terms of the posterization test, are the videos included low bit rate contents? Are tvs other than the LGs supposed to be completely free of posterization when playing those videos? Because yesterday I tested them on my Sony A95L, which is supposed to be very good at suppressing banding and posterization, and I still saw some mild posterization. Just mild, not very bothersome, but still visible, so I wonder if the sources themselves have posterization. I kept smooth gradation setting disabled btw.

The Stranger Things, Liongates and Silo clips have slight banding/posterization in the source, but you should watch the original clips rather than the YouTube versions.

The C2 and G5 show a lot of banding and posterization in HDR10, but DV is practically clean. My Samsung HDR10 monitor, on the other hand, shows no banding/posterization at all.

Hi @RESET9999 and every other people.

I contributed in the past in this forum as a proud and happy owner of a Chromecast with GoogleTV(CCwGTV), but since june's Android 14 update with kernel 5.15 Google broke DV FEL playback.
So now I'm looking for a replacement and I'm decided to go with Amlogic SOCs with full DV FEL playback on CoreELEC CPM .

I'm in doubt bettween:

• Ugoos AM6+ (Amlogic S922X-J) (of course)

• Homatics Box R 4K Plus / Dune HD Homatics Box R 4K Plus (Amlogic S905X4-K) (the new kid)

Ugoos was my first option after reading RESET9999 detailed review and recommendation, but I'm also considering Homatics based on next tips.
Source: https://docs.google.com/spreadsheets/d/ ... id=0#gid=0

The good:

• High Bitrate via Wi-Fi 6 (faster than Ugoos).

• AV1& AV1 with DV and HDR10+ capable (a difference of Ugoos).

• Premium Streaming (Netflix, Prime, Disney+, etc.) via Android TV (a difference of Ugoos).

The least good:

• SOC less powerful than Ugoos, but moderately snappy.

• Slower CE boot via mSD card or USB device.

The questions that matters:

• Both devices would give the same image/sound quality?

• Homatics have full CE driver support (ethernet, Wi-Fi, bluetooth...) as Ugoos?

• Amlogic S905X4-K is newer and could have Amlogic longer term support that could bring better future functionalities?

• Ugoos will have a better CoreELEC maintainers support that could bring better functionalities?

• Any other appropriate questions that you can contribute.

Please, can you give me your advice?
Thanks in advance.

Get the ugoos, all the other devices drop frames with FEL playback. CPM A14 has perfect playback and doesn't really need any update so we are good forever...

It cannot be explained better with fewer words.
Decision made. I'm going for the Ugoos.

As always, thank you very much RESET_9999

Yes I downloaded the original clips and watched them on my a95l via the ugoos.
I did see mild banding/posterization mainly in those 3 clips.
Hopefully lg can fix the g5 and their future oleds, but I doubt it.

Well, my old C2 also has tons of banding/posterization in HDR10, so I guess LG indeed will never fix HDR10. Thankfully, they get DV right.

Is there a difference between DV and HDR10 on the Sony?
On Samsung TVs and Monitors, the image is clean, so I suspect Samsung might be doing some undefeatable smooth gradation under the hood.

I don't see any obvious difference between hdr10 and DV on the Sony in terms of posterization.
The Samsung is completely clean even with the 3 clips you mentioned?

I talked to someone who had the new Samsung OLED TV but ended up returning it due to poor uniformity. He told me all the clips were completely free of banding and posterization.
I only have a small Samsung OLED monitor for my PC, and it’s also pretty much clean, maybe with slight banding if you look very close. Funny thing is that my Samsung oled phone is worse than the G5 HDR10 and looks horrible.

Additionally, the G5 in HDR10 exhibits undefeatable dithering noise in all areas below 10 nits. Really a bad choice for anyone watching HDR10 content.

So strange. It dolby vision is clean on the g5, it means the panel tech is not the culprit, no? It also means there is no reason lg cant fix hdr10? I heard the panasonic z95b which uses the same panel has good hdr10 with almost no dithering noise, but bad dolby vision. It's like these manufacturers are intentionally playing with us.

[RESET_9999]

yeah I dont understand why they dont just do the same as DV.

Is ugoos still the only device to support Positive Lift(L2/L8 offset) and Level 5 Active area in TV-LED?
