I'm at a loss here as to where to go next or what to do. I've largely been holding off posting here thinking I could figure it out but here I am...

My laptop, an ASUS ROG GL553VD, is working almost flawlessly. The specs are identical to the one linked here: https://github.com/duydoanx/gl553vd-opencore-macos-big-sur. The issue I cannot resolve is connecting an external monitor through the HDMI port.

I started from scratch, following the guide but struggled with getting the Trackpad to work. After several headaches, I have essentially copied the one from that GitHub link and updated it to be in line with OC 0.7.1. I've read over the framebuffer pages, looking for something I've missed, used Hackintool to help me build a patch for my config.plist file and I get nothing.

Here is windows (NVIDIA CP) reporting my external display when it is connected:

NVIDIA Control Panel

The guides would tell me that I should be able to use the HDMI port as long as the dGPU is disabled. However, when I add the boot flag (-wegnoegpu) or the disable-external-gpu property to the config.plist, I cannot use the external monitor.

Removing that flag or property, I get the following within IOReg

Laptop Display Framebuffer 0

External Monitor (HDMI) Framebuffer 1

Now, I could keep the boot flag or property out of the config.plist file, but if my computer makes any attempt to sleep with those values missing, the screen stays black.

I'm out of ideas, hoping someone can see my mistake or clue me in here.
