I'm running W10 as a host and guest, using VirtualBox 5.1.22. When the guest upgraded itself to the creators edition, the display driver lost support for the physical monitor resolution (and no longer sees the second monitor I've allocated to the VM.
I've tried uninstalling the guest additions and reinstalling them. And I've tried the development build to see if that fixes anything. It doesn't.
I've tried adding a custom display resolution to get the main display working. That resolution doesn't come through as an option in the guest. (And it wouldn't fix the problem of the second monitor.)
Does anyone have W10 Creators guest running with multiple monitor support?
Any suggestions about how to fix this?
Many thanks.
