So I don't need to look up for a connector port number on windows? I had take a look to find this number, perhaps this was a mistake.

It should not be a problem to switch the language to english on windows when I will upload new pictures, if this will be need.

But we need the right connector port to get the second display working on macOS, right?

No idea if that is even possible.
There are only three possible ports anyway. Easy enough to try them all.
 
could you tell me these ports? :)
 
For all they have a Yoga 720 I used this patch for:

KextToPatch:

com.apple.driver.AppleIntelKBLGraphicsFramebuffer
Find:
02040a00 00080000 87010000 03060a00
00040000 87010000 ff000000 01000000
20000000

Replace:
01050a00 00080000 87010000 02040a00
00080000 87010000 ff000000 01000000
20000000

So my external Display is working now, thanks to @RehabMan

You will see different ones enabled in the various ig-platform-id data (in the kext binary).

are this ports same for hd530 ?
 
I can verify that this patch works on my Yoga 720 15 for usb c hdmi and mini display port adapters. A few questions though, If I boot with a monitor connected, the laptop boots to a black screen and neither display will come on. Unplugging the external adapter has no effect on this. If I boot, then plug the adapter in, all is good.
Second, This works on mac 14.1 but not 14.3. Isn't 14.3 a better match for the yoga? I'm just curious about the difference.

I'm thrilled to get an external screen going, the questions above are just to help me understand.

Thanks

Note I have the same issue, I'm using MacBook Pro 14.1 smbios.
I also need to reboot the system till external and internal display work.
The issue here can pointed to the acpi tables which I can't patch. But I can work with it when I know how it works.

Perhaps someone has a idea but I think no.
