Setting up dual monitors on your Dell computer can save you from having multiple documents minimized in your Windows tray along the bottom of your screen, and can keep you from having to print documents unnecessarily. Dual screens give you more workspace, allowing you to move documents that you would otherwise have to print to your secondary monitor while you keep your work at hand open on your primary monitor.

Step 5

Click "Detect." Click the dropdown icon to the right of "Multiple Displays." Select the monitor setup that works best for you. The list of choices will include: "Duplicate these displays," "Extend these displays," "Show desktop only on 1," or "Show desktop only on 2." "Duplicate these displays" will display an exact copy of whatever you are doing on both screens. "Extend these displays" will allow some of the Windows icons to spill over onto your secondary monitor, essentially creating one large desktop. Showing the desktop only on either the primary or secondary monitor will display your Windows home screen on one monitor—the other monitor will display only the background.
