Apple Macintosh PowerBook 190 Series - Manual (Page 70)

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.
1 Make 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.
