Dell XPS 7590 BigSur HDMI sees two screens on disconnect

[stakeout5]

Hey! I fixed sleep and all that. Now i have one small issue left.

Issue:

When the laptop is booted and logged into BigSur and I plug in the HDMI cable, the machine registers it and my second display works great. No issues. It is when I go to unplug it, the first time I plug/unplug everything works as normal and the laptop recognizes that the HDMI cable was removed and the display changes back to just the laptop screen. The second time I plug/unplug the laptop doesn't recognize that I disconnected the HDMI cable and remains thinking that there are two screens still. (All settings and such allows me to configure the second screen like it is still there even though it is unplugged. I can also move applications off of the laptop screen to where the "second screen would be" and they will stay there like it is still plugged in.) I'll attach a link to my config. Any help would be great.

Hardware:

• Laptop model: Xps 15 7590 4k IPS, 16gb RAM, 512gb ssd, dual boot with windows 10 pro
• CPU: i7 9750h
• GPU: uhd 630
• Audio codec: Realtek 298, works with layout-id 30
• Bios: 1.8.1, offsets changed for undervolt and cfg-lock
• Install method: Opencore 0.6.4
• Secondary source for refinement: https://github.com/xxxzc/xps15-9570-macos

Thoughts? Here is my new RunMe

 

Thanks.
