Connecting an external monitor
IMPORTANT You must install a video-out upgrade card to use an external monitor with your Macintosh PowerBook. Contact your Apple-authorized dealer to purchase the Macintosh PowerBook 8-Bit Color Video-Out Upgrade Kit (which includes a PowerBook video adapter cable), and for information on which monitors are compatible with your PowerBook.
When equipped with a video-out upgrade card, your PowerBook has a video port to which you can connect most Apple monitors. To connect an external monitor, you need the PowerBook video adapter cable (which comes with the video-out upgrade card).
In addition to many Apple monitors, your PowerBook supports most VGA and SVGA monitors. To connect a VGA or SVGA monitor, you need an additional adapter, which should come from the same source as the monitor.
Once you have installed the video-out upgrade card, an external monitor connected to your computer can function as an extension of your PowerBook’s built-in screen—that is, you can drag objects from one screen to another and do your work on either one. Or you can show the same image on both screens (a feature called video mirroring).
To connect an external monitor, follow these steps. Also consult the documentation that came with the monitor.
1Make sure your computer is shut down or in sleep.
If you connect a monitor with your computer turned on, the computer will not recognize the monitor.
