Connection of an external Monitor to ZVA

Question

I have a new ZVA with Windows 7. When I connect a monitor it remains black.

What do I have to do?

Go to the desktop of Windows and do a "right click"

Graphics Options --> Output to

--> now select the external monitor

VERY IMPORTANT:

Before you disconnect the external monitor, do not select "Build in Display". It must be set to "Clone" or "Digital Display"

If "Build in Display" is selected, the internal monitor of the ZVA remains black!
