Issue with monitors on new build.

Hi everyone, I need a bit of help with my build. It is the first time I am building a hackintosh. The specs are below. I got everything working using the OpenCore Install Guide, but have an intermittent issue with my monitors. Occasionally, my secondary monitor (I have two connected) would stay off and I would have to reboot. After reboot both would work. There are no similar issues in Windows. I have tried everything I could think of but can't get any closer to why it's happening. Any help would be appreciated.

Also, I am preparing to add my Apple account to the build, but I am worried of being locked. I have an iPhone and a MacBook, and it would be a problem if my account got blacklisted. I put in a serial which said "serial number isn’t valid" on the Apple check. Do I need to be worried?

System identifier: iMac19,1

CPU: i5-8400
RAM: 16GB DDR4 2666
Motherboard/Laptop Make and Model:
Audio Codec: ALC892
Ethernet Card: Intel Gigabit onboard
