How to Connect Two Monitors to One Computer
- 1). 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.)
- 2). If it can't, buy a monitor switch box and connect both monitors to it. Or buy a new video card that has dual monitor ports.
- 3). If it can, buy and install a second video card. Read "How to Install a Video Card," for installation instructions.
- 4). Reboot the computer.
- 5). Set preferences for your new monitor in the Display control panel under System Preferences (Macintosh) or in the Display control panel (Windows).
