HDMI/DisplayPort not working. Only DVI works.

Is it possible to get them all work at the same time? This is my first Hackintosh build, the parts are as follows:

  • Intel I3 8100
  • Gigabyte H310M Motherboard
  • AMD RX 460 GPU
  • 8G DDR4 *2

I plan to use the Displayport on the AMD GPU for 4K output as I am purchasing a new 4K monitor, but currently I can only get the DVI port on the GPU to work. I have tried connecting an old monitor to the HDMI ports (on the AMD GPU and the iGPU) but end up with a black screen. So only one DVI port is working right now and all other ports including HDMIs, VGA, DisplayPort don't. Can somebody have a look at my EFI file as attached and point out where I get wrong. Thanks a million!
