MacBook Pro 2017 internal display is disabled when eGpu is connected
I noticed that the drivers for the Radeon dGpu on my MBP was out of date, so I updated them. But now when I boot Windows with an eGpu (Aorus 1080), the internal screen of MBP just stays black. When I check Radeon settings, it says "no display connected".
If I boot Windows without eGpu, internal display works just fine.
Any ideas why this might be happening?
I'm not sure we're on the same page.
I could run the internal display on Radeon Pro 555 (not Intel iGPU), and run external displays connected to the GTX1080 eGPU at the same time. On Windows. After updating the Radeon drivers, I couldn't do this anymore.
I was able to uninstall the drivers, and install the old ones that came with the Boot Camp package, and now I can use the dGPU and eGPU on Windows at the same time again.
I assume this is a driver issue since older drivers just work fine?
Macbook disables the iGPU (Intel) when boot into Bootcamp, only run dGPU (AMD). When you plug the eGPU (Nivdia) in while boot into Bootcamp, Macbook also disables the dGPU and only uses eGPU. You can run both dGPU and eGPU if you plug the eGPU in after boot into Bootcamp or use this method .
