40 Chapter 3 Using Your Computer
You can also display and record computer images by connecting a TV, video projector,
or videocassette recorder (VCR), or play DVD-Video discs on your television, using an
Apple Video Adapter, which is sold separately. The Apple Video Adapter provides
composite and S-video connectors for TVs and other devices.
When an external monitor or television is connected, the same image appears on both
the internal display and the external monitor (known as video mirroring).
If you want sound to come from the external display, such as a projector or TV, you
need to connect an audio cable from the computer’s headphone (audio line out) port
to that device.
Note: Because of the display limitations of most televisions, images displayed on the
television screen will be of lower quality than those on the built-in display or an
external monitor.
Connecting an External Display or Projector
To connect an external display or projector with a VGA connector to your
computer:
1 Turn on the external display or projector.
2 Connect the VGA display cable to the Apple VGA Display Adapter, and then connect
the adapter to your iBook G4. Your iBook G4 automatically detects the external display.
Important: To ensure that your iBook G4 automatically detects the external display
or projector, be sure the Apple VGA Display Adapter is plugged into the external
display or projector first.
Mac OS X automatically selects the display resolution and frequency appropriate for
the device. You can adjust the resolution on an external display by using the Displays
pane of System Preferences or by using the Displays icon in the menu bar.
Note: Your iBook G4 doesn’t support external display resolutions above 1024 x 768.
