Well, this is a completely different device. The connector mapping is unique for every device. Do you have a dGPU in your model?

You can try to use the Whatevergreen config without support for multiple displays via Thunderbolt. Checkout older commits. If this is not working, then you have to do try and error with your Whatevergreen config. See lspcon connector which is the HDMI port:

framebuffer-con3-enable AQAAAA== framebuffer-con3-alldata AwQSAAAEAACHAQAA enable-lspcon-support AQAAAA== framebuffer-con3-has-lspcon AQAAAA==

Also read the OpenCore iGPU mapping guide: https://dortania.github.io/OpenCore-Post-Install/gpu-patching/intel-patching/connector.html https://dortania.github.io/OpenCore-Post-Install/gpu-patching/intel-patching/busid.html#parsing-the-framebuffer

In addition, take a look at the block diagram of your laptop's logic board to understand how the display ports are connected to the CPU.
