Hi willie83, it took me a while to find why this is happening.
This Intel® Server Board uses the SMI LynxEM4+ graphics controller instead of Intel® HD Graphics.
Drivers are available for the operating systems listed here: https://downloadcenter.intel.com/Detail_Desc.aspx?agr=Y&DwnldID=21299
Let me know if you have further questions about the Intel® Server Board, I can try moving this discussion to the Intel Server Community if needed.
