External Video Port

The PowerBook G4 computer has a video port that provides S-video output to a PAL or NTSC video monitor or VCR. The video output connector is a 7-pin S-video connector. Figure 3-9 shows the arrangement of the pins and Table 3-17 shows the pin assignments on the S-video connector.

An adapter (included) can be plugged into the S-video connector and accepts an RCA plug for connecting a composite video monitor.

The PowerBook G4 computer provides video output at picture sizes and frame rates compatible with the NTSC and PAL standards; the picture sizes are listed in Table 3-18. Those picture resolutions produce underscanned displays on standard monitors.
