I have been reading through and I am seeing conflicting information about eGPU support.
Does the 2018 MBP with dGPU (Vega 20) support eGPU with the new 19.1.2 V3 drivers?
If so, does it require the EFI hack?
Will it support displaying the eGPU output on the laptop LCD?
Will the same drivers support the laptop's dGPU and a Vega 64 in an eGPU?
I have run the installer with success without the eGPU plugged in. Once I plugged in the eGPU, Windows was unable to just determine and install drivers on its own, so I tried to re-run the installer. This caused the laptop LCD to blank and the system appeared to be hung at that point. Any advice would be appreciated.
UPDATE: I actually had an HDMI issue that's been corrected, so now I can tell that the eGPU will only work when a monitor is plugged in AND I boot with the eGPU plugged in, first. If I boot with the eGPU plugged in after, I get the error Code 12 on the eGPU device. I don't see much of an issue with having to boot with the eGPU plugged in, if it would also work on the internal display, as well.
