Second Display on Ventura

Hi' all I am running OS Ventura 13.4. Overall the system is pretty smooth, though I am facing an issue connecting my iPad or Macbook as the extended display from my Hackintosh system. I have never been able to do that.

They just don't appear on the settings on my hackintosh, ever!

Second, I have never been able to log in app store too, I wonder if two of these issues are connected. I have no idea. Can anybody please help?

I would appreciate all your help. Attached is the EFI I am using.
