Thats what i am running my second monitor out of. To set up dual screens go to the display setting in the control panel. After that, you will most likely want to choose extend my windows desktop and click ok. Anyway, the process is realatively easy, just make sure your second monitor i(port-dvi in your case) isn't disabled. It took me a couple of days to figure out why my 2nd screen was booting up black!!!
