What happens if you use 444, 10bit and GUI set to 2160p.(And adjust the saturation). On my TV 720, HD and UHD including HDR is perfect:) What happens on your's??
ps. Minde that the GUI Colors will be different than the video;)
I managed to get my scripts to work. I added 2 buttons to the Movies sub menu, with 8-bit and 10-bit and now I can switch between the two modes almost on the fly.
I didn't try it, but I also don't want to calibrate my TV this way, I don't see a point or how it can work just as well as it's supposed to in SDR.
Interesting. Sadly I don't have an AVR which can show me what the output signal of the box.
My issue is with my TV switching into BT.2020 mode even in SDR mode if I use 10 bit output, this messes SDR up.
I guess I'll just have to come up with a script to enable 10bit for when I want to play a HDR video and disable it after playback has started so that the box comes out of 10 bits when the playback stops.
Regarding 1080P vs 2160P and color issues, I guess your best way to tell is to check what the AVR is saying. But it's possible that the TV responds differently to a 1080P 10 bit signal than it does to a 2160P 10 bit signal.
I just tried adding a button to the skin UI to execute the echo '444,10bit' command, but using System.Exec just locks up Kodi.
Well looks like I can't execute the echo command directly from Kodi. I guess it does not have permission to edit the file?
Doing this via a Python script doesn't work either. Any help would be appreciated. I rather not to rely on an external device to switch between the two modes, and would prefer to do the switching directly from Kodi's UI.
Any help would be appreciated.
What 4K non-HDR calibration videos do you have?
I just run my GUI at 4K and don't bother with it.
But ok, whatever works best for you. I have an LG, so maybe they behaves differently.
How do you know? With LE 8.2.2.2 I see no difference in color between the box and the TV's built in player for HDR content. With LE 8.2.1.1 there was a significant difference between 10 bit and 8 bit output from the box.
This means that 10 bit works just fine now. Make sure that you're running the latest LE 8.2.2.3 build.
HD and UHD are resolutions. So are 2160P (aka 4K) and 1080P.
I assume that when Kodi GUI is at 4K you get BT.2020 label on the HDMI input info, but in 1080P you don't?
I suggest you remove the 444 10bit entry from autostart.sh and see if that fixes it.
SDR should look the same, regardless of content or GUI resolution. There is no benefit forcing 10 bit out of the box for SDR content.
In one word: What?
Most of what you said makes no sense. 2160P and 1080P are resolutions. "UHD" usually refers to 2160P or 4K resolution.
Either way, I have yet to test this with a meter, but it looks like with the latest builds 10 bit is now automatically enabled when you play a HDR10 video. Thus, there's no need to set 444 10 bit anymore.
I have 2 boxes:
Sunvell T95N 2GB/8GB, works great. I think that LE7 didn't have wifi. On the latest build of LE8 (8.2.2.2) Wifi works just fine.
Sunvell T95M 2GB/8GB, again works great, currently on LE7 and I don't plan to upgrade as LiveTV in Jarvis works a lot better and faster. The only gripe is that the front LCD doesn't work.
I think neither have access to the internal NAND (running them from an SD card), but I don't mind that.
You could get a USB hub...
I apologize for the noob question, but what does PR stand for? Pre-release?
The Coolest, 'Tim_Taylor':
When i set manuelly set 444 10bit then the outbut show this, but i will see what set the "auto detect"?
After setting 444,10bit, and changing refresh rate\resolution, my LG B7 switches into BT.2020 SDR, which looks terrible, so I don't understand why you want it so badly. In HDR content color looks fine whether you have 444,10bit enabled or not, in 8.2.2.2. The only problem I had was with color in HDR content being undersaturated on older versions of LE.
Today I noticed sound crackles and video stutters in my IPTV live streaming (IPTV Simple Client). I'm using a Sunvell T95N 2G/8G box and have LE 8.2.2.2 on it. Never had a problem with LE7. I don't recall having this problem with 8.2.1.1, but I haven't used it that much before updating to the latest build.
The streams don't run out of buffer, but this problem still occurs. Is there any more data you need? (Sadly I can't provide a playlist, as it's a paid service)
Don't use 10 bits with an LG. It'll screw up SDR, and won't improve anything in HDR.
I have a B7 too.
The Coolest : How do you check 8bit or 10bit HDR is active in Kodi?
How can i set Kodi to 444 10 bits? I can only set the Resolution to 2160p
You can either SSH into LE, and run the following command:
echo '444,10bit' > /sys/class/amhdmitx/amhdmitx0/attr
Or you can simply add it to autostart.sh file, so that it'll be applied every time LE boots up.
This will take effect once kodi switches refresh rate or resolution if you do it from SSH.
In my case it caused issues with SDR, as my TV went into BT.2020 mode, and all colors were oversaturated.
But it seems that it's not needed anymore in the latest builds for correct colors in HDR.
Just updated my Sunvell T95N to 8.2.2.2.
Wifi is now back and working. It only has 2.4GHz and no BT, which LE displays correctly. Awesome!
I also checked HDR10 content with and without setting 4:4:4 10bit. It now seems that color saturation is identical to in both 4:4:4 10bit mode, 4:4:4 8bit mode and in the 'default' mode (after a reboot) on my LG TV. Compared to the TV's built in player, it now looks the same, which is great news to me.
So I just wanted to ask whether it's something that was fixed after 8.2.1.1? I saw that the rgb_output was brought back in 8.2.1.2, could it be what fixed the issue I had before? (Before I had to enabled 4:4:4 10bit, otherwise in HDR content color was undersaturated, even though the TV would kick into HDR and BT.2020. And now it seems fine)
Thanks again for the work you and the other devs do for everyone 
kszaq And one more request, looks like GDPR-2 has added support for the LCD display on the TX3 Mini. I have a T95M, with the same display.
I was wondering if it would be possible to add this to your builds as well, or install it later (I assume there needs to be a driver for the LCD + updated tree?)
Happy Christmas everyone!
GDPR-2 can you please describe how you enabled clock on TX3 mini's LCD?
I'd like to know as well. I have T95M (S905X), which seems like it has an identical LCD module.
