This is similar to a more well-known issue where the computer won't boot past logo screen with an eGPU attached to the EC2 slot, but in this case it's the external monitor.

Thinkpad T430, i7-3632QM, 8GB RAM, Windows 10 pro 1703, BIOS ver. 2.79
EXP GDC 8.5c with expresscard, MSI GTX 1070, Corsair HX850.
Samsung S32D850T monitor, connected to the DVI port on the GPU via a HDMI to DVI adapter. 

Everything works fine without the monitor. It gets recognized, newest driver installed, no error 12, error 43 fixed with the script:

The problem is if I try to turn on the computer with the monitor attached to the GPU, it would not get past the logo screen. Also works flawlessly if I attach the monitor after the logo screen. Exactly the same issue except it's the monitor not the eGPU. I played with the PTD switch on the EXP GDC but it did not seem to do anything.

If I attach the EC2 adapter after the logo screen it does not get recognized at all.

I don't like having to plug and unplug the monitor every time I turn on the computer, so any advice on how to get around it would be appreciated. This setup has worked before on an Acer E1-471G with a mPCIE cable.

Pending: Add my system information and expected eGPU configuration to my signature to give context to my posts

Would your system be shutting down? Is that what you mean by not going past boot screen? or do you mean it gets stuck or restarts?

This could explain my issue. Thanks!
