State of eGPU for Macs – Mojave 10.14 Update  

Version 10.4.3 I think

@nanoBit - FYI, I was able to make the built in display no longer black by simply uninstalling the AMD drivers that Bootcamp installs.  So, Windows thinks it's an unknown display adaptor but it seems to work fine regardless.  I do not use it for any display acceleration instead using an external display with my Titan X.  But it works fine for having a web browser, YouTube, etc up on the laptop display while gaming or what not on the external display.

Edit - Clarification, I didn't use DDU or anything only went through the standard Windows uninstall programs and removed the AMD stuff.

@sharpnl sounds good! But I use the dGPU often when I travel, so it needs to be accelerated and I'm curious if there are any performance differences without the AMD driver. Would you mind running a benchmark (Cinebench preferably) without your eGPU being connected? Just to see if there's a performance loss.

I would wait a couple of releases to install on my prod drive as I see that there are some performance issue with GPU in general.

@shrapnl Uninstalling the drivers isn't necessary. Just disable it in the Device Manager and it should do the trick. Then one can enable easily on the go.

Problem solved! Disabled the dGPU, rebooted and it works! Both display work. Booting with the disabled dGPU and an unplugged eGPU is possible, too. Unfortunately hotplugging is still not working, showing the same error again. (BSOD, ks.sys being the cause) Interestingly it is not possible to change the resolution of the internal display 🤨

@nanobit Hotplug should work if you plug in to the right hand side port, and have anything else unplugged. If you plug in something to the remaining right side port, eGPU may disconnect. After hot-plugging eGPU, you can plug in stuff on left side ports. This also means no need to disable dGPU.

You can read more about the investigation from this post onwards.
