My primary monitor is attached to my onboard video card. My secondary monitor is attached to my PCI-E card. When I first start my computer, only the primary monitor is on, and it is the only monitor that is recognized.

While I'm in Windows 7, if I turn on my secondary monitor, Windows 7 automatically detects it, and expands my desktop to stretch across both monitors.

But if I turn off the secondary monitor, Windows 7 doesn't automatically disable it. Is there a way I can get it to automatically disable when I turn it off, or is there a utility that makes it easier to disable it instead of having to go to screen resolution?
