Con0 port is not defined. How many video ports are there on the system?

Connector 0 is LVDS with internal display connected (I think so cause I see in IORegistry - see screenshot)

When I connect HDMI cable in system.log appears :

Your profile indicates that you're using a Desktop. So are you using LVDS port on that?

It's not Desktop, its all-in-ones mono block. Display connects to Motherboard via LVDS bus.

And the other video ports?

And the other video ports?

Motherboard has no other video ports. LVDS and HDMI only.

Define Con0, Con1 and Con2.

 

[Kpbicka]

Define Con0, Con1 and Con2.

Done! No connectors. LVDS - work, HDMI - no signal

Are you using Ventura?

You cannot expect it to work as none of the connectors are defined. I already mentioned to define con0, con1 and con2.

I use Ventura
that's why I'm asking for help to correctly identify the connectors, because on my own I can't

Remove the following keys
-AAPL-slot name
-device_type
- model

Define the connectors with the help of Connector patching

You just need to define 1xLVDS for con0 and 1xHDMI for con1
