This is what I found. There are 3 ports: a HDMI 2.0, a HDMI 1.4 and a DP. For both HDMI 2.0 and DP, I got screen shots of IOReg and Hackintool attached. For HDMI 1.4, once it is in use, the system's boot up process hangs; I cannot even get it boot into safe mode. Looks like Port 5, 6, and 7 are HDMI 1.4, HDMI 2.0 and DP, respectively, right? What to do next? Thank you.Yes, the tool has no way to know what physical connector is.
Connect the display to each connector and make an IOReg.
Reply with 3 IORegs.
Nothing attached.I got screen shots of IOReg and Hackintool attached.
No Intel HDMI audio codec present:DisplayPort audio was working originally but then stopped
