Mojave 10.14.6 on a HP envy x360 Shutdown issues

[hauntix]

Hi so I have a near perfectly running Hackintosh but I've come across 2 issues:

- HDMI display is not being detected
- When I try to shut down the screen goes black but the laptop is still running (backlit keyboard stays on, fans still running)

I've tried searching to see if anyone else has had similar issues and couldn't find anything related. Would anyone be able to direct me in the right direction or help me diagnose what the problem is and how I may be able to fix it?

bump - Came across a new issue today when attempting to use an external display (cause reboot, was able to somewhat fix this but now the external display isn't being detected.
