You don't have to physically disconnect any of your displays to turn off the multiple monitors feature. With Windows 7, you can access your display settings through the control panel to quickly turn monitors on and off. In the "Display Settings" window, there are on-screen representations of your monitors. Windows automatically assigns each monitor a number, so it's easy to distinguish between monitors and select the ones you want to turn off.
