Sidecar connects but shows only Black Screen

• Probably a dgpu model problem only. Users on the main fork of this EFI related sidecar working just fine! That's why I did not remove it from the "What's Working section"
• Not correlated with SMBIOS. Users shows different MacBook Pros with T2 chips SMIOS working just fine! Also tried MacBookPro 14,1 and it did not help
• It could be a disabling NVIDIA patch problem. -wegnoegpu makes no effect tho, so im not sure
• Most probably it could be the IGPU only supporting H.264 and not HEVC encoding. With the little information I found on actual laptops, it seems like this could be a culprit (not sure tho, the information on laptops is almost none, even on Dortania guides)

Obs: it's not related to continuity features itself! The iPad is connected, both wired and wireless, and Universal Control (as other continuity features) works as it should!

Further testing with disabling the DGPU shows that this isnt an DGPU related problem:
I updated the method of disabling to the device-properities one and, although it worked fine, sidecar is still broken. I will start to work on the IGPU Patch, as this seems to be the issue.
