Sorry late to the party, received the Mininx and flashed the Ugoos firmware LATE last night, are we saying choosing TV-Led processing causes incorrect colours with HDR10 and SDR?

Why is that even a thing? TV led processing should only affect Dolby Vision, does HDR10 not pass through?
What TV do you have?

Yes, for some reason that's how it turns out. With DV off, you can choose the combination of output bit depth and chroma, and RESET_9999 has tested SDR/HDR10 content and found that at 12-bit 422 the output is accurate and at 8-bit 444 it's slightly inaccurate (other output bit depth/chroma combinations e.g. 10-bit 420 might also be accurate, we just don't have test results for those).

However, with TV-led DV on, for some reason SDR and HDR10 content is forcibly output at 8-bit YCbCr444, and you can't change the bit depth and chroma. HDR10 metadata still passes through, it's just that the output colour depth is 8-bit, and strangely even SDR content also has slightly incorrect colours. It doesn't really make any sense why SDR/HDR10 content is forced to be output at 8-bit YCbCr444, because when DV content is played, it changes to output 8-bit RGB anyway.

With LLDV on, all content (SDR/HDR10/DV) is locked to output at 12-bit YCbCr422. This is correct for LLDV content and (coincidentally?) SDR/HDR10 content too.

Without further information it seems like a bug or oversight, because it doesn't seem like there's any good reason to restrict the output bit depth/chroma for SDR/HDR10 content when TV-led DV is on (of course, DV content should still be restricted to 8-bit RGB). It should be easy for Ugoos to fix it. In the meantime, we can switch TV-led DV on and off to get the most accurate colours.

I should have said that this device is the best android device in terms of capabilities but definitely not for stability. Especially when you are used to the stability of the x700 and an HTPC.

Once you start changing the colorspace settings, the device becomes very very buggy(i have not really tested plex).
Sometimes:
- DV gives a black screen, rebooting fixes that,
- DV just won't trigger DV: it even tonemap profile5 to HDR10
- HDR10 trigger HDR but without any metadata: just 12bits 422 bt2020, nothing more.

I don't see how someone would use this device without an hdfury device to tell if your current mode is the right one.
profile 7 is also VERY unstable (freeze, stutter, tv goes black, audio dropout), sometimes you have to start the movie 4times before it plays correctly. Profile 5 seems stable.
Hopefully, things get better with future updates but as for right now, I will still use my x700.

It would be really nice if we could convert
P7 bl.el.Rpu to propper profile 5 with the funky colors.

To be honest, I gave up looking for different players, takes too much energy, time and effort. I settled between Sony X700 and Fire TV Stick 4K. Movies with MEL, I convert to MKV and store it in my NAS so I can watch it later with Fire TV. For other titles with FEL ( the ones I deeply care about it ), I am gonna use your method with Blu-Ray folder in the root of the flash drive/HDD and enjoy it that way. Even some titles I started converting from FEL > MEL for convenience sake.

Do not use Kodi. Plex and the factory Media Player app are stable.

Plex is not an option for me because I want lossless audio.
Does the media player app support lossless audio and DV ?

What is your display and what options do you have available under Dolby Vision display settings?

And you have “Dolby vision enable” turned on correct? Not LLDV.

Thanks. I also cannot play MKV with DV through the inbuilt player with LLDV. It works with modified Kodi. I wonder how others have it working on inbuilt player..
Edit: I’ve been told inbuilt player only supports DV with MP4. Not sure if this is correct, haven’t tried MP4 yet
