Error is gone...but now (as it did sometimes before) hd audio bitstream stutters sometimes, especially DTS:x... Also with a brand new live Libreelec. I think that is an error of the lspcon, I have fw 1.66. DVI works fine. Picture of hdmi fine too, but audio starts popping... I think it has no relation to the screen error.
Perhaps I will just use the 4205 for a server and get a j5005 or 4105 for Kodi....starts getting on my nervs.
But thank you so much for your personal help! So at the end the aspect error on HDMI was a configuration error, wherever it was from.

Thought I'd try a Milhouse nightly build on my UP Squared N3350 Celeron board (until recently serving pfSense firewall/VPN duties).
I'm running it via a Displayport 1.2->HDMI 2.0 3D Club converter which handles proper 2160p50 and p59.94 output.
Watching the BBC iPlayer 36Mbs 2160p50 HEVC Wimbledon stream which is wide colour gamut Rec 2020 with HLG EOTF it's interesting to see what happens with my Apollo Lake.
I'm getting 2160p50 RGB 8 bit output (594MHz) - with what looks like a Rec 2020 to Rec 709 conversion. It doesn't seem to be Rec 2020 incorrectly output as Rec 709 (as some platforms deliver) - it does look as if Kodi or the Intel drivers are doing some gamut conversion. No idea how accurate it is - but if I force Rec 2020 colour gamut, it looks very, very wrong. The SDR backwards compatibility of HLG HDR seems to be pretty effective too.
I'm getting very occasional dropped frames - and initially it takes a while to work - but I'm pretty impressed that a low-end Apollo Lake can do this at all.
(It's a passively cooled Celeron with a chunky heatsink the size of the board area. But goodness does it get hot...)
Also interesting that the 2160p50/59.94p output is 8-bit, but 1080p, 720p and 576p is 12 bit.

It was easy to implement it and to create an infrastructure. It was meant to set a basis so that you freaks :-) with the good knowledge can jump in and implement better suited operators :-). Btw. check the code again - you should see the handling of BT2020 and how we produce sRGB.
First decide what functions / features you expect from a system. Then decide for the hardware. Don't waste your money on crap.
