Hi All:
I'm using a 2012 MBP with a DualHead2Go. I run a VirtualBox VM with guest OS Windows 7. I need a way to 'trick' my VM into a different resolution. In the alternative, I want to set a manual resolution for my Windows VM, to confine it to one of my monitors. Specifically, I don't want my Windows VM to span both of my external monitors.

Any thoughts?

Have you installed the Guest Additions inside the guest? If not then see the user manual, section 4.2.

Yes, I have.
