Intel VAAPI howto with Leia v18 nightly based on Ubuntu 18.04 server
Short explanation:

As you can see i am using the internally called DP2 port. My board ( uses alpine ridge to convert the displayport signal to all full flavourd hdmi 2.0 signal. But randx does not report 2160p 60hz. If i try to use the other hdmi port (the board has two) it reports to use internally called "hdmi3" port and i get no signal at all.
