I have a 10 bit monitor (LG 31MU97Z-B)
Connected with the DP Cable to a ASUS Mainboard (PRIME Z370-A)
The Intel Grapics driver is the newest one.
I will only get 8 bit and not the 10 bit.
There is no option and I have no idea what to do.

Intel graphics does support 10-bit and 12-bit color depths (known as deep color). However with our current driver implementation the color depth will be set as per the OS configuration. Normally under Windows -> Display settings -> Windows HD Color section you should be able to enable HDR and WCC (wide color gamut) which would configure the OS for higher color depths. Please note that if the content you are trying to view is 10-bit once you switch to Full Screen mode the driver will switch to said color depth as well (mostly on DirectX applications). More information about our current implementation can be found here
Obviously things have changed and more and more displays support > 8-bit and even Windows 10 (after 1703 update) supports 10-bit, hence we are working on improving our Intel Graphics Command Center application to allow users to manually select the preferred Color Depth. This change is a work in progress so please give us more time (I cannot provide an ETA yet).
