Hello,

it's well know all the trouble the dGPU Radeon 560X causes, even though it is quite easy to get internal display running at all
(just deinstall the Radeon Drivers in order to be driven by the Microsoft Basic Display Adapter)

But this has a price:
-You cannot start DirectX Application on the internal screen, you get errors.
- You cannot change resolution:

Any attempt to change this has been futile:
1) Enabling the iGPU (e.g. by EFI Loader) anf installing the Intel Drivers results in the infamous white dots with black screen.
2) It's not possible to reinstall  AMD Drivers, trying yields an "Error 173 - AMD Installer cannot continue sinc AMD graphics hardware was not found"

So my question ist:
Has there been ever any successfull attempt with the 15" MPB 2018 driving the internal display under Bootcamp with the correct drivers?

Yes it's possible with an Nvidia eGPU. I was able to use GTX 1080 Ti + XG Station Pro eGPU through the 2018 15" MacBook Pro internal display. The trick was to hot-plug the eGPU. If you boot the system with eGPU attached, the dGPU will be disabled. I was not able to replicate using an AMD eGPU.

I do have exactly this setup and my internal display was running from the beginning, but unfortunately only with this Microsoft Basic Device Adapter, where I cannot change the resolution.
Which driver is running you internal display? Can you change the resolution of it? When exactly do you hotplug?

Internal display should work fine if NVIDIA eGPU is hot plugged. No need to uninstall AMD drivers or anything.

Ok Thanks, I was finally able to re-install AMD drivers and hot-plug e eGPU with success. Two questions remain:
1) The Hot-plug does not work very often. Is there some trick or hint?
2) How do I get fullscreen eGPU acceleration into the internal display?

Hi all,

Thanks for all the info so far. 

I am trying to get XG station pro + Vega 64 (295W TDP) to play in win 10 on MBP 2017 15". So far it looks like the acceleration is working okay (very high CPU usage though) however my resolution too is stuck at 3360 x 2100. 

Reading in between the lines and will do more research on this issue but this res issue is unsolved is that correct?

  1. Hot-plug during the spinning circles while Windows boots, and ensure no other devices are connected to any of the Thunderbolt ports. Once booted, you can connect devices to the opposite side ports. Hot-plug works best with right-side ports.
  2. Windows has GPU preferences per application. Set that to high performance for the apps needed and they should use eGPU.

@mac_editor: thank you for your replies.
1) Thank you, I got it by now, but it's completely different to the hot-pluggin of 13" MPB2015. And I can do it only once.
2) I guess it won't help that the Radeon GPU is not listed as "Power Saving GPU". How can I change that?

Everything I launch on internal display will be accelerated by the 560X. I can launch on external display and drag it into the internal, but there is a significant performance loss.

@oliverb The power saving GPU needs to be the 560X. IIRC both are the eGPU if the 560X drivers are not installed/not installed correctly. Ensure that the 560X is accelerating the internal display and fully functional. This has been done multiple times by @itsage and myself so just re-read the findings on the forum.

@mac_editor
The 560X is accelerating the internal display to well. It's accelerating every application launched from there. Oen thing is different in my setup compared to others: For a long time I didn't even have the AMD Drivers installed, because for an eGPU with external display they are not necessary at all. I guess my setting is coming from this fact. It may help to uninstall the nVidia Drivers and reinstall them again to get the correct order.

BTW: It seems to be impossible for 15" MBP 2018 to run the iGPU: White dots and black screen only.

Just to clarify, and sorry for reviving a dead thread, but this is currently not possible with an AMD eGPU, correct?
