I suspected as much because of the different video port configuration on your motherboard. Please try the Framebuffer patching guide linked in my previous reply. If you get stuck, please post an image of the FB-Patcher Connectors page and any specific changes you attempted, and we'll help.There is still no signal on HDMI port on second monitor after booting to Mojave os. Displayport is working with first monitor though.
