I've already made as many patches as I possibly can for you there wouldn't be any difference. Every patch I made for you you said failed to work. I have no mobile graphics to test with, you've already made more progress with it than I ever though would be possible. You said yourself that injectATI=true causes boot failure and my patches require injectATI=true and FBName="Whatevertheframebufferis"

Before you try some different framebuffers, could you tell me what is the monitor model that you are connecting to display port? If I saw correctly from one of your previous screenshots, it should be LG e2242. That one doesn't have display port so you must be using some sort of adapter. If that is the case try with HDMI to DVI adapter and report...

I am using a LG E2242, yes. It doesn't have DP, so I'm using an adapter.
I'll try and find an adapter and see if that makes any odds. I can always use HDMI instead of DP, doesn't matter.

Same results using HDMI

the reason I say this is my card almost exactly matches the Hamachi framebuffer in the AMD7000Controller.kext and it even worked great for me natively in all versions prior to High Sierra but then I had to try different framebuffers. The framebuffer doesn’t really matter which one you choose to patch because you are patching it.

Okay I'll give it another shot later on

Pavo actually fixed it but the post #50 is from may 2015...You can try his patch (with HDMI connected instead of displayport), I added zeroes to be compatible with high sierra framebuffers:

00040000 04030000 00010500 00000000 10000505 00000000
00020000 04020000 00010401 00000000 10000406 00000000

If it doesnt work for you, it's possible that something other than the framebuffer could be the problem in your config...
