This is a Zotac CI547 box. It has to video outputs: one HDMI and one
DisplayPort. The HDMI port appears as DP-1 in the logs, the DisplayPort
as DP-2. The hardware is Intel HD 620 and is allegedly able to run two
displays simultaneously at 4K. I have one WQHD monitor (=2560x1440) and
I get that full resolution over the DisplayPort. However, I would like
to also get that resolution over the HDMI port (in order to connect two
identical monitors), but over HDMI I only get 1024x768. Updating the
kernel to the latest 4.18.8 using UKUU made no difference.
