Devices and Ports
54 External Video Connector
An adapter is available that can be plugged into the S-video connector and
accepts an RCA plug from a composite video monitor.
The 1999 PowerBook G3 Series computer provides composite video output at
picture sizes and frame rates compatible with the NTSC and PAL standards; the
picture sizes are listed in Table 3-13. Those picture resolutions produce
underscanned displays on standard monitors.
