Black screen after login screen : Ventura Gigabyte H170M-D3H with HD530

Hello,

Finally I succeeded to install Ventura on Gigabyte H170M-D3H i3-6100 (skylake) with HD530 IGPU with OpenCore 0.9.9.

It boots fine til login screen, but after 2 second monitor turns into black. Sometimes it helps to disconnect HDMI cable and attach it again.

Spoofing kabyl lake works.

Any idea or help?

Regards!
