enable HD630 along with GTX770 for multi-monitor

I am trying to enable both iGPU and dGPU to power my multi-monitor set up. I got it to work with a previous built (Sierra, GA-Z77X-UP5, HD4000 + GTX1080) by using Framebuffer patching in my device properties. I can't seem to figure it out for my current built (Mojave).

bios and clover boot shows up on the IGPU. Once boot into Mojave, only the dGPU come on, the iGPU go black.

I removed the dGPU, and only use the iGPU... same thing, they stay black.

bios setting: iGPU as primary multi-monitor support enable

any help is appreciated.
