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?
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.
• Have you tested the Intel® NUC connected directly to the SONY® vw270es video projector or other display? :
Yes, but same issue, no possibility (even not a dropbox list option somewhere) to choose sub sampling chroma.
• What is the brand an model of the RAM and SSD on the Intel® NUC?
RAM : Crucial CT2K8G4SFS824A 16Go Kit (8Gox2) (DDR4, 2400 MT/s, PC4-19200, SR x8, SODIMM, 260-Pin)
NVME : Samsung SSD Interne 960 EVO (250 Go) - MZ-V6E250BW
With the asked document in attached file. (Connected to my TV Samsung 55UE7500 at the moment i have do the report).
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
