Hi all,

First post. I've had a great experience with my Mantiz on my 2017 MBP due to a lot of the well detailed guides on here. So thank you in advance for that.

However I am experiencing an issue when booting into Windows (Bootcamp) without my eGPU connected. My internal video card (Radeon Pro 560) simply doesn't display anything. When the eGPU is connected everything is fine running on the external RX 580.

With the eGPU connected if I view device manager I noticed my dGPU is disabled by windows and reporting code 43.

I've seen a lot of people experiencing this error code for their eGPU but I can't find any threads with it being the dGPU.

Has anyone any pointers before I go about adding and removing drivers.
