Can someone please help. Trying to do a simple EGPU Setup?  

What GPU?
I have to plug mine in when after boot selection when the Windows logo first appears.

It's Razer Core X with Nvidia 1080 Ti. Man, I am so frustrated for not being able to do it. What's the initial basic setup I need to do to make it work?

Anyone with the solution? I'm almost at the point of returning Razer Core X, I bought it only after reading that it's a straightforward hookup if you want to just activate your external display. Seems like I will not get it working.

First of all, setting up an eGPU in Boot Camp for the 2018 15″ MacBook Pro is not a simple process. Most reports and my experience included have the top right Thunderbolt 3 port to work best on the 2018 15″ MacBook Pro. Why do you use the top left Thunderbolt 3 port to connect the eGPU? Take a look at this post where @mac_editor tried different approaches.

I'm not looking to have internal display working. I only want external display activated and from what I have read here, it looks like it's straightforward. I just need to see some steps which I need to perform to exactly achieve that. 

Something like:

Step 1: Install Boot Camp
Step 2: Plug eGPU
Step 3: Go to Device Manager and disable X Y Z.

Any help in this regard will be extremely appreciating. 

You should post some screen shots of the errors you are getting as that will help folks help you out...

Just trying to get a simple freaking system work. I have new Boot Camp windows installed and my 15" Macbook Pro 2018 is attached to Razer Core X and an HDMI is running from Core to my TV. I can't get display up my TV. I only want external display to work at the moment but I have spent around 14 hours now on this damn thing to get it work.

Can someone please help me?

This is where I am. I have uninstalled dGPU with DDU and now I am having Error 43 on NVIDIA.

Oddly enough, I'm having a nightmare with my set up too now... I wonder if new Nvidia drivers are to blame? Anyone else having error 43 issues with 10xx series cards?

edit: this was solved, OP hadn't plugged his GPU in correctly, and my power cables had been knocked so needed readjusting.

Im having the same problem,
MacBook pro 2017 non TB 13"
Razer core X
GTX 1070TI FTW
Windows 10 Bootcamp

If I hotplug the box to the macbook while its running, theres a weird blue screen with shite patches and the macbook reboots. Any tips?

Plug in your egpu after you select windows from the bootloader. You’ll need to be quick, I have to plug in just before the spinning dots appear (so it’s just the windows logo on screen when I plug in).

Ok I resinstalled Windows and upgraded to Mojave.

Now if I hotplug it, it dosent crash and reboot. Instead, its not being detected at all, tried plugging it in just after the windows logo appears a few times.

Ok update: I hotplougged it into the other port and Windows detected it.

IT says "Microsoft Basic Display Adapter" under device manager now.
