You can use these test patterns: http://cellarcinema.info/temp/uhdtest.zip
Open the pictures with 'right mouse button' edit on W10.
I can't get 4:4:4 with ASRock and LSPCON HDMI 2.0

Yep I'll give it a go when I get home.
EDIT:
I have tried that Quick Brown Fox picture and all of it (including the last two lines) looked like it displayed properly.
The ChromaRes only shows 4:2:2 so I assume that this means I am not getting 4:4:4 then.

I could get 4:4:4 mode on a Samsung UE48JU7580.
But I had to enable 'HDMI UHD Color' and change the HDMI input type to 'PC'

Ah!
I had HDMI UHD Color set already. My Input type was set to "HDMI 2/DVI" so that I could set "Movie" picture mode. Setting to "PC" allowed me to get 4:4:4 chroma.
I have a Samsung UA55KS8000WXXY.

Looks like there is a 1.65 firmware for the LSPCON.

Seems to fix some frame rate issue.

Thanks. I reinstalled Intel HD Graphics and got it semi working. Really strange as I had already reinstalled it once before and that did not help. But it's still not 100% stable... I get random audio drop outs now and again when using Spotify and Tidal (PCM). But strangely bit streaming DTS MA and TrueHD now seems to work fine. To be honest I think the Intel HD Graphics and/or LSPCON firmware needs some further developments/updates... At least it seems the LSPCON supports these formats :-)

They don't appear in the supported formats, however I am only running audio through my TV speakers at the moment, which doesn't support HD sound (DTS and Dolby Digital do work though).

Thanks for checking...
ChromaRes.png... I also get 4:2:2 only
TextTest_1920x1080.png... red/yellow text is not vibrant, red/blue text font not pixel perfect
TintBlueRGB.PNG... the word red/magenta looks like 3D

My setup:
J3455-ITX FW 1.2
LSPCON FW 1.61
Club3D 3m 4K HDMI cable
Philips 43PUS6101/12 (HDMI 3 4:2:2/4:4:4 enabled)

I'm trying to get Intel to expand the features of the HD graphics control panel (force YCbCr 4:4:4).

Happy to report that it has been over 8 days now without any issues.
Display has come back every time after monitor sleeping, and no audio loss.
Think it might finally be working! :-)
