HD530 (Spoofed): How to find correct framebuffer settings if DisplayPort connector ist not even shown

Hi everyone,

I'm currently having some issues with setting up my PC on Ventura and Open Core 0.9.7 (OCAT + Hackintool).

My PC has the following specs and everything is working flawlessly with the exception of the second DisplayPort connector on the mainboard:

• Mainboard: Fujitsu/Kontron D3433-S1x
• CPU: i5-6500T Skylake with HD530 iGPU (spoofed as HD630)
• 12 GB of DDR4 RAM
• Wifi & Bluetooth: Dell DW1830
• SSD: Crucial MX500

So everything's working fine, including Bluetooth, WiFi, Airdrop, etc.
Apple ID is also working fine.

But the second Displayport is not recognized at all.
I can see that it's functional since on boot up, the boot screen of the MB is showing but once I'm in MacOS there's "No signal". The other port is working fine and display resolution of 2560x1440 is no issue at all.

Since this is a 49" DWQHD monitor, I guess it should also be sufficient to run 5120x1440 but MacOS is not providing such an option and tools like SwitchResX or BetterDisplay result in a heavy flicker when using applications.

No what I tried is:

• My current Settings:
  • PciRoot(0x0)/Pci(0x2,0x0)
    AAPL,GfxYTile 01000000
    AAPL,ig-platform-id 00001B59
    device-id 1B590000
    enable-hdmi20 01000000
    framebuffer-portcount 04000000
• Use Hackintool to get the framebuffer config

This is with both DisplayPort connectors connected to the monitor


As you can see the second DisplayPort is not mapped here.

Btw.: framebuffer-portcount 04000000 was added afterwards but had not effect :(

Do you guys have any idea?
