Not yet. I try to figure out if it does have a PCON chip. NUC documentation says it does. But it does not make sense because Tiger Lake-U has a native HDMI 2.0 controller.

A user reported that HDR does not work with my build on NUC11PA.
-
There is no HDR support in Linux for legacy LSPCON chips. Patches exist but they have not been merged (yet).
PCON DP 1.4 -> HDMI 2.1 is already properly supported. I see no reason why there would be an issue with HDR.
-
It will probably work fine, support in Linux is already there.

I suspect the issue started after samba was updated to 4.13.4.
As a workaround you can use the ip instead of a host name and it will work.

DRM PRIME decoder must be enabled.
I don't use audio passthrough. Some people reported glitches with HD-AUDIO (same as with the official builds).
-
Yes. You can use a build from post #387.

Ok, I'm out of ideas.

There was a linux commit that fixed a similar issue on some Gemini Lake boards with ITE66317 HDMI retimer.
I will modify that patch so it would work on Gigabyte Brix. I will post a build for you to test in an hour or so.

Could you run:
lspci -vvn -s00:02.0
and post the results?
-
And with the official images all 4K modes (3840x2160 23.98/50/60 Hz) work?
-
I see nothing useful in that log file.
Does it lose the signal after any resolution change? 1080p modes too?
-
Is passthrough audio really that important? Why not just use PCM?
-
They should work but no one tested it yet.

Panther Canyon NUCs use Intel Tiger Lake SoC.
-
All Tiger Lake chips have the same (Gen12) GPU. The difference is only a number of enabled EUs (48 on lower end Celeron 6305).

I googled the picture of the Brix Gemini Lake mainboard. For some bizarre reason, it has PTN3366 HDMI level shifter (a chip near the HDMI port).
That chip is not HDMI 2.0 compliant and probably causing these issues.
