Nuc8i7beh how to set 4k60hz 420 bt2020?

Hello, have recently upgrade from a hdmi 2.0 nuc to this nuc8i7beh with hdmi 2.0a for Netflix, hdr and atmos.

I reach this at 24hz, but as I don't see any option in the Intel graphic panel to set subchroma, I'm at bt2020 444. And if I go to 60hz, it keeps 444 so hdr isn't possible due to restriction of hdmi 2.0 18gbps bandwidth.

I'm sure of my video projector capability and cable, as I have a shield tv as secondary source which works really fine at 4k 60hz bt2020 10bits 422 hdr10.

So, how to set my iris 655 to output at 60hz 10bits bt2020, with a 420 or 422 chroma subsampling? Or it isn't possible with this nuc, thanks to poor driver and I have to return it and go for a normal pc with a nvidia card?

Thanks all.

to add details :

 

My nuc is connected to a yamaha RXA1070, output to sony vw270es videoporjector. They are HDCP2.2 compliant, 4K and HDR compliant.

 

Il under windows 1809, last update done, last driver versions of intel drivers trough their utility online.

 

I have HDR on, not on RGB but in YcbCr (yuv).

 

What i try to achieve is to be on YcbCr but as intel driver set auto on 4:4:4 and as it isnt possible with hdmi 2.0x to send 4K60hz@4:4:4 withHDR10 (22 gbps versus 18gbps), with a chroma of 4:2:2 or 4:2:0.

 

I have look everywhere without any solutions so far.

 

For info, i also own another PC (my gaming one) with a 1080ti, and with this one, i can set 4K 60hz BT2020 (YCbCr) 422, with HDR10 on, and play AC Odyssey for exemple. Or play the whole netflix catalog, as with 24hz netflix catalog is restricted in term of picture quality.

 

Really hope there is a trick.

Hello GBize Thank you for waiting. Allow me to share with you that right now there is no way to manually set Chroma Subsampling, this happens automatically based on the system and support offered by the TV e.g. if you set up your graphics properties to 4K@30hz and using HDMI 2.0 and the TV supports it, the Graphics driver will set up the output to 4:4:4, if you raise your configuration to 4K@60hz the system will lower Chroma Subsampling to 4:2:0. We are working adding this feature for future releases. Regards, Leonardo C. Intel Customer Support Technician Under Contract to Intel Corporation

well i wait for the next rleases so, because atm in 60 hz the card still set 4:4:4 , so it over come the HDMI norm (18gbps max, at 4:4:4 60hz in 4K, its 21GB wo HDR).

 

Im stuck until Intel give the feature (in 2019, it's kinda a shame to not offer as a basis this configuration on GPU ...).

 

But at least now, i know :d

 

Thx
