Dolby Vision for Minix U22X-J (Max) and Ugoos AM6+

Thank you, I did use forum search but the installation guide that I was pointed to was the link I posted which didn’t have the extra steps in it.

Thanks for the link, I will check top copy over the other files, I assume the installation guide I did use (the one I linked to) is outdated? Then again maybe I did miss some link or something to the dovi steps.

And not to mention that if the resolution is set to 1920x1080 and your TV is 4K, any material less than 1080p gets upscaled only to 1080p by the box and after that upscaled again to 4K by the TV which is suboptimal.

Just got my AM6B Plus in the mail a few days ago. So far everything is working well, but I’m having a tough time getting CEC to work properly. After looking through this thread, it seems I’m not the only one. My issue seems to be that the AM6B+ is “locking” CEC/ARC for the other inputs, even after I suspend the AM6B+. I first noticed something was wrong when I couldn’t adjust the volume for the Apple TV through the remote app on my phone. I checked the settings in the Apple TV and it had switched to “IR” instead of “HDMI” for volume control.
I also noticed that something was weird when powering down the Apple TV failed to power off the TV (LG CX). My setup is:

LG CX
Sonos ARC soundbar
Apple TV
PS5
UGOOS AM6B+

I ended up having to disconnect the TV from the power outlet to get normal functionality back. I have since discovered that simply switching the audio source on the TV also sets things back to normal.

Has anyone else experienced similar behavior?

Does anyone know if there ever was a MINIX NEO U22-XJ with 64GB but WiFi 5 and 4.2 Bluetooth. So 64GB storage but not the MAX Version.
I thought they were all 32GB before the MAX came out.

Same issue here with a Philips 808. Only solutions were suspending or disconnecting Ugoss’s HDMI. So I just suspend Ugoos with TV now. Changing sound settings didn’t help.

The upscaling in Kodi is pretty confusing. I would propose to simplify it to the Zidoo method. Two options. Either match frame rate, or match frame rate and resolution.

If match frame rate and resolution is selected, then all resolutions are sent to the TV as is, and the TV does all the upscaling.

If simply match frame rate is selected, then the box does all the upscaling.

Kodi’s method with the whitelist is confusing as hell. If you set 4K GUI, then box does all upscaling unless you configure whitelists for every resolution. If you set 1080p GUI, then native 1080p content is upscaled by the TV, while anything lower is double upscaled unless whitelist is set.

I think Zidoo has the right approach here since nobody wants both Kodi and TV to both upscale. Either the TV does it all, or the box does it all, and it should be independent of the GUI resolution. Just two options keeps it sweet and simple.

EDIT: I actually prefer Kodi’s upscaler to the TV. These algorithms are very well known and the processor in the TV is not necessarily faster or better.

My LG G2 is powered by the alpha9 processor, no details are given on RAM/CPU, but anyone trying to play MKV or MP4 remux from WebOS can immediately see that performance is much worse than our S922XJ boxes. WebOS in general is slow, glitchy, and laggy. It’s not just OS issue, but plainly seen on playback. That’s why even on streaming apps people prefer ATV or Shield Pro to the TV apps.

Why would upscaling be better on the TV then? I’ve tested many many times, and have always come back to Kodi’s upscaling vs the TV. I think the S922 isn’t a weak chip, and the HW may even be better than what is within the TV.

Of course this is all preference / opinion, but I just don’t think TV upscaling as a rule is better.

Who says this for LG? For years it was the biggest negative for these TVs as a non owner. Seems since last year it’s better.

Well just got my new Mini U22x-J MAX today and would like to know if there is any guides on getting kodi installed and booted thanks

Then here, you can pick and choose whatever settings you like best, but this is a start:

Why would you whitelist 4K resolutions? Included or not, there is no need for any upscaling of 4K video by Kodi or TV.

No need to be pedantic. Obviously not 4K since it doesn’t need to be upscaled. But every other resolution.

So what’s the best options in kodi re best picture quality?

PQ is depend on hardware (chip) and firmware, nothing related to kodi cause it is just a player?

For 4K content no difference since it is just passed to TV.

For SD content, I prefer Kodi to do 100% of upscaling, and I think it does a better job than my LG G2. So you need to set GUI to 4K, that’s it. No need to do anything with the whitelist.

If you prefer the TV to upscale, then you need to whitelist all the resolutions below your chosen GUI resolution. Eg set 1080p GUI and whitelist everything below. Otherwise you will get double upscaling, both box and TV. Could be using different algos, just not good.

I think best way CE could simplify is remove the whitelist entirely and just add a single option. Match resolution or not, yes/no. If yes then TV upscale. If no then Kodi upscale. No GUI resolution dependency.

It is unclear to even seasoned Kodi users what is going on, and the out of the box setting automatically introduces double upscaling on SD content.

do you mean SD?

There’s this oddity in Kodi in which it checks for matching exact or double refresh rates when whitelist is considered. This can easily lead to the box upscaling to 1080p instead of outputting the material as it is (or upscaling to 4K). I have a patch I apply whenever I build CE to get rid of those two cases.

Right now, Kodi upscales to the smallest resolution in the resolution. I wish Kodi had a setting to choose to between the smallest integer resolution and the highest integer resolution. So if the TV does not support SD, you can choose to scale to either HD or UHD. This should eliminate double scaling. However, this seems like a Kodi issue and not a Coreelec issue.

If there is no match, Kodi will upscale to the set resolution which is why I’m using that patch. For example, 720p at 23.976 or 24 fps is not supported by HDMI and cannot be whitelisted → Kodi outputs 4K if the resolution is set to 3840x2160p if that patch of mine is used. Otherwise it will match with a whitelisted 1080p choice and outputs 1080p.

Yes, typo. That’s what I mean, on SD content it is double upscaled out of the box with a 4K TV.
