No display while graphics accelaration on - DELL Latitude 3500 laptop

Hey! I've installed macOS Ventura with OpenCore on my DELL Latitude 3500 laptop.

I've been struggling to get graphics acceleration to work. When it is disabled in the config.plist file, the laptop screen works, but no HDMI/VGA out. When I enable graphics acceleration on the config.plist file, the laptop display does not work, and HDMI/VGA does not work either, but VNC remote control works.

This is the structure of my EFI folder:
