I have a new NUC11ATKC4 which is connected to a Samsung TV MU8009 with an 8k HDMI cable.
Unfortunately I can not make it run in 4k@60 Hz with 4:4:4 subsampling. In ""Intel Graphics Command Center" I can either choose 60Hz and 4:2:0 subsampling or 30Hz with 4:4:4 subsampling.
I know, that I need to enable "UHD Color" feature for the HDMI port in my TV's setup menu. But if I do so, the screen stays black (no connection possible).
If I connect my Lenovo notebook with Ryzen CPU and Radeon graphics to the TV using the exact same HDMI cable on the exact same HDMI port then everything woks as expected (4K@60 Hz with 4:4:4 subsampling or RGB mode), at least when "UHD Color" mode is enabled for the HDMI port on the TV.
I wonder if the Celeron N5105 in this NUC is even capable of doing 4K@60 Hz with 4:4:4?
Can anyone verify on it's own machine and tell me?
Any Ideas of how to debug what signal or screen meta data is seen by the NUC when "UHD Color" mode is on on the TV for the HDMI Port?
