If you have a Windows computer, see if your current video card can support dual monitors. (Read Microsoft Knowledge Base article 182708 at support.microsoft.com.)

Step 4

Reboot the computer.

Step 5

Set preferences for your new monitor in the Display control panel under System Preferences (Macintosh) or in the Display control panel (Windows).
