The situation is a little bit weird.
This card works with a HDMI -> DP adapter, but not working with a native
DisplayPort screen (EIZO 2316W)
There is no display on boot, can't see the vendor splash screen as well.
Also, we have another card here with the same name / PCI-ID on 201302-12727
it works well with the native DisplayPort screen.
I'm not sure what's causing this difference.
