Playing HDR video crashes libreelec and TV displays 'No Signal'

That's some progress at least

I will now do another build with some changes.

I think I can fix Ethernet.

Your vainfo output doesn't look right. Looks like Tiger Lake require Intel's media-driver which I did not include in my build.

I will post another build in an hour or so. Please re-test HDR and Ethernet.

I think the reason why they used PCON is space constraints of the NUC motherboard.

mDP + a native HDMI would require routing separate traces from SoC to HDMI and mDP ports.

mDP + HDMI with PCON does not require extra traces for HDMI, probably DisplayPort MST function is used.

I have no means to check why it does not work. It does look like PCON may be an issue, but it's all speculation at this point.

We need to wait for hardware with a native HDMI port to make any conclusions.

As soon as consumer Mini-ITX Tiger Lake boards are available I will buy one of those.

Thanks to @luckylukz it's now confirmed that NUC11PA does indeed use a DP->HDMI protocol converter.

The driver detects 5 available connectors: DP-1, DP-2, DP-3, DP-4, HDMI-A-1.

"HDMI-A-1" is a native HDMI but it is not active when the TV is connected to a NUC's HDMI port. DP-3 is actually active which means that a PCON is used.

**smp** · Intel true 10bits/HEVC/HDR support... ? **smp** February 17, 2021 at 9:34 PM

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.

**smp** · Intel true 10bits/HEVC/HDR support... ? **smp** February 17, 2021 at 9:21 PM

A user reported that HDR does not work with my build on NUC11PA.

**smp**

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.

**smp** · Intel true 10bits/HEVC/HDR support... ? **smp** February 16, 2021 at 8:53 PM

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.

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.
