I have the same problem, but have tried with the latest driver and Windows version.

Can you boot that VM with a Ubuntu installer LiveCD? Not to install Ubuntu, just to see if the desktop environment of the installer shows on a display connected to the GPU. Recent Ubuntu versions come with Linux drivers and should just work. That would be a good test to see if the passthrough is configured correctly.
