How to enable HiPDi on Mohave with RDM custom resolution?

Hi
I started all over..from begging and created a USB Boot Drive for Ventura, but I got this weird sign in the middle of the screen..is white. I found some info online explaining that I must boot the USB from a 2.00 port, and the USB drive must be 2.00 also.

Please, I need your advice on it

Do not mix threads about different issues as this thread is regarding something else. You can either have one single dedicated thread for a system covering all the issues or each separate thread for the issues you may have.

Anyways I have just installed Monterey, But it boots on Black Screen and Apple Icon is Huge. I can't provide PR files it does not boot at all. Any way on how to make it bootable again

Check my EFI

The configuration is not upto the mark.

Starting from the first, the EC-USBX SSDT is still corrupt, PMC should not be used here.

The reason for black screen is due to the wrong SMBIOS selection. Use iMacPro1,1.
