Open Hackintool, navigate to the tab, and look at the index list (Index 1, 2, and 3). You will need to trial-and-error cycle through these indexes to find your physical HDMI port. Add the patch to your config.plist : By default, many Intel framebuffers define ports as

Ensure you are using the latest version.

Look for the recommended layout-id or AAPL,ig-platform-id . For example, a desktop Coffee Lake iGPU typically uses 0300923E . Step 2: Enable Framebuffer Patching
