Just plug the video into one of the HDMI ports, then plug the audio into the other. Then configure the audio to the port you plugged it into. No need to configure the video.

Yeah it was 23.95, and my lumagen reported that as well. I ended up using a new build and applying the 10bit patch to it. All fine now.

portapro I made a quick rebuild of my last community version with the force YCbCr 4:4:4 patch.
download image here https://sky42.libreelec.tv/testing/intel-yuv444/
here is the full source https://github.com/sky42src/Libre…-240324y-yuv444
this commit you can pick for your own build if it works for you https://github.com/sky42src/Libre…7d8a8158956b078
Edit:
Short test on my N100 -> X6700H -> OLED55E6D show it does what it is suposed to do. All is in YCbCr 4:4:4 says the info screen of my Denon with or without HDR10.
You may run into audio trouble when playing 2160p @ 23.976 Hz and using pass through.
quick workaround is to only use 10 bit not 12
systemctl stop kodi && intel-gpu-max-10-bit.sh && systemctl start kodiThis works perfect, i have to use the 10-bit option otherwise i get dropouts.
However i noticed that the video output refresh rate is 23.95, not 23.976 which creates stutters. Any ideas?

4K60 is only two movies in my whole collection. Where we need is HDR10+ support, which is backwards compatible to HDR
-
LibreELEC doesn’t support playing 4k60 HDR files yet. Also you should set the gui to 1080p 60.

Any update on playing 4k60 files?

I just leave my NUC running. No issues so far.
-
I went for an Asrock N100M
Still installing and configuring, but first impression is 👍🏻
HDR working ok and gigabit LAN?
-
Is there any newer build available? I'm still using build devel-20220807005106-45816fd
If there is no newer one available, could you provide one? smp
Or is HDR available on official builds already?
I'm using Intel NUC7PJYH2
HDR is in the nightly builds.

I built a 12th gen ITX system and it worked fine for HDR except any 4K60 files. Everything else is fine with my JVC projector.

LE spent a lot of time doing performance testing on chipset specific flags during OE days when our Generic userbase was larger and hardware was somewhat slower that it is today (and thus such flags had greater impact). Our conclusion back then was that the flags do technically make a difference, but the gain is so marginal in the wider context of things that influence system "performance" (esp. I/O performance) that it's not worth the effort. And then we killed off chipset specific builds. The idea (re)surfaces from time to time; mostly among the retro gaming crowd who constantly seek overclocks and optimsations, but (still) never seems to hold up to any real scrutiny..
I understand, I’m more interested in the YCbCr output. No performance advantages.

It should boot on NUC11. It boots fine on my Tiger Lake box.
The image was built with -march=tigerlake gcc flag. It would probably be unbootable on non-tigerlake CPUs.
What about a Nuc 10th gen. I have one of those I can test with
-
This image will use YCbCr 4:4:4.
This build won’t boot for me on Nuc11

At this point, I'm convinced this NUC11TNKi3 isn't willing to do more than 8-bit video output from HDMI2 (HDMI1 is I think is a displayport).
atoulmin can you tell me exactly which NUC models you have gotten to work with your projector?
Nuc12
RNUC12WSKi50Z00
Nuc 11
BNUC11TNKI50000

I'm just trying to trouble shoot.
I know I can play these files back with corelec at 10bit on my projector, but I don't think it is outputting in RGB, i think it is YCbCr (and bt2020).
RGB 10 bit won't play on my projector for some reason, although it looks like it should be able to, according to the manual (and other people with a similar projector aren't having problems?).
I'm a bit stymied. If I can't figure this out, I think I'm going to try and RMA this NUC.
edit: is the lack of a 10 bit color profile (bt2020) the reason that 10 bit rbg isn't working?
I agree that it should be an option to output YCbCr, why not?
There is no issue with your NUC a new one won’t fix the problem. I’m surprised it’s not working though, as I said I have a JVC X5900 which is the series before before yours. It has no issues with the default signal. However it would be nice to have the option.
-
YCbCr support would be nice but I think it’s up to Intel.

From JVC NX5 manual:
When the color space is RGB/YCbCr(4:4:4), only 8-bit input is supported.
^ There's your answer. You will have to use 8-bit for 4k/24Hz.
systemctl stop kodi
./proptest -M i915 -D /dev/dri/card0 308 connector 314 8
systemctl start kodi
try if 4K/24 now works
Upd: the manual actually refers to 4K 50/60Hz modes, so deep color should be supported with 4K/24. Try also 10-bit (./proptest -M i915 -D /dev/dri/card0 308 connector 314 10)
I have the JVC X5900 which is the model before the NX5. I don’t have any issues with HDR on my NUC 11 or 12 gen.

well, sounds like I need to get 24hz, or rather 23.98hz working. anyone have any ideas on that? I’m not sure what is going on with my video pipeline. I tried copying the edid, but that didn’t help. I’m not totally sure what the Prime DRM decoding does, but it doesn’t seem to affect my problem on or off.
I did manage to get HD audio working (with playback at 60hz).
Looking at your log, it looks like you have your Kodi gui set to 3840x2160.
This should be 1080p as you don’t want Kodi scaling anything. When you select a 4K video it will switch to 4K and the right colourspace.
So change your resolution in the menu to 1920x1080 50/60
Then make sure match video frame rate on start and stop is on. It then should switch to 4K 24 BT2020 for playing movies. See how that goes.
