I've got two monitors. When I play a full screen game in my primary monitor, the second monitor still shows the Windows desktop. How can I black out the second monitor so that it doesn't show anything at all? My graphics card is from ATI.

I'm running Windows 7 in Boot Camp on an iMac. I don't know if this makes a difference, however, as any solution to my question will do, really. For instance, is there a tiny app that I could run to disable the second monitor for a while? I'd rather not have to open Windows display settings every time I run a game and disable the monitor that way, though.
