Hi,

I have a brand new 2018 13" Macbook Pro with 2.7 GHz Intel Core i7, 16 GB 2133 MHz LPDDR3 and Intel Iris Plus Graphics 655 1536 MB.

I bought a Sonnet eGFX Breakaway Box 650 and fitted an Asus RX Vega 64 ROG STRIX OC (although it barely fitted in the box).

In am running Windows 10 Pro in BootCamp with a 200 GB partition. I installed the Asus drivers and their tweak utility and everything worked absolutely perfectly out of the box with no changes to the OS, EFI or boot. As long as I plug thew Sonnet box in before I boot and only have my monitor plugged into the graphics card it boots perfectly into windows and I can use the computer without any problems. I am also using an HTC Vive perfectly (although I have to make sure it's unplugged from the graphics card before I boot).

However, I do get the Windows logo on the internal laptop screen and it stays there, flickering occasionally.

I really want to be able to disable the laptop screen, is there a really simple and reliable way that I can just stop this screen from being active?

-Shutting it doesn't seem to actually switch off the screen (I'm pretty certain it's still on, just shut).
-I have tried hot-plugging the monitor at various stages of Windows boot but the internal screen is only usable in that situation, not the eGPU
-I have tried booting from apple_set_os.efi but this didn't work for me

I'm pretty technical but Windows is a total mystery to me and I literally cannot make head or tails of how to get this screen to just switch off. I have read through these forums quite extensively but just cannot find something to work.

Thanks,

Phillip

The stuck Windows logo screen is due to deactivation of the iGPU when Windows recognizes the eGPU is to take over. The internal display is attached to the iGPU so it hangs at the precise moment the eGPU starts working. Try automate-eGPU EFI boot loader and see if you can get the AMD eGPU going while keeping the Intel iGPU activated.

Hi,

Thanks for the suggestion, I have tried this but it doesn’t seem to work for me.

When I try and boot with this from a USB stick I get the Apple logo several times, sometimes I get asked to connect to wifi and eventually it reboots (I have to remember to hold down the option key so that it doesn’t boot into MacOS) but then I still have the Windows logo stuck on the MacBook and the External display actually starts to act in an odd way (the resolution is low).

@snoek Have you disabled Security Boot? The Apple T2 chip doesn't allow booting from an external source by default.

I have disabled that and I can boot from the USB and it is booting using it but it doesn’t seem to have a positive effect. It seems to impact the eGPU’s display if anything, reducing its resolution.

Hi theitsage, 

I have the exact same issue as Snoek described. Thanks for your prompt answer I have then acknowledged the flickering Windows logo is due to deactivation of iGPU. This occurred since I installed Win10 on an external SSD, and I connected the eGPU to the only workable port without disabling other ports.

I am interested in shutting off the main display as well however, is it gonna negatively affect my MacBook pro's hardware lifetime with the flickering Windows logo on?

Thank you, 
Zane
