@interobang,
The black screen problem with motherboard HDMI port is just a framebuffer connector issue. Mojave assumes all ports on your board are DisplayPort so we have to apply a patch to specify HDMI. The procedure for this is in this guide:
[GUIDE] General Framebuffer Patching Guide (HDMI Black Screen Problem)
General Framebuffer Patching Guide using Hackintool Please do not quote this guide in its entirety. Post a link instead. 15 Jan 2019: Intel FB-Patcher has been renamed to Hackintool. 19 Jan 2019: Guide overhauled. Please be aware of possible HDMI hot-plug issues.

But it’s better to plug your monitor into the RX580 and set your BIOS —> Initial Display Output to PCIe Slot 1.
The RX580 should be listed in System Preferences under Graphics/Displays. Fans won’t spin until temperature reaches 50C or so under load.
What is the make and model of the RX 580?
It's a Sapphire Pulse Radeon RX 580. Bought that because it was the most supported and recommended. Is it not?
Initial Display Output is set to PCIe 1 Slot, but still no signal. I've also replaced my config.plist with the one you edited (thank you very much!). And deleted that patch you suggested. However, I still get no signal. How can I tell if it's something like a malfunctioning card? It is brand new.
Is it worth getting the onboard HDMI working so I can at least boot into my new system and have a look around at what the problem might be?
I am still getting a lot of ??? in Hackintool. Is this a good way to diagnose system condition? Or does that not tell you much because I'm booting into my USB drive?
