The PowerBook computer has an S-video connector for composite 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 3-13 shows the pin assignments on the S-video connector.
Table 3-13 Pin assignments for the S-video output connector
| 1 | Analog GND |
| 2 | Analog GND |
| 3 | Video Y (luminance) |
| 4 | Video C (chroma) |
| 5 | Composite video |
| 6 | Unused |

An adapter is available that can be plugged into the S-video connector and accepts an RCA plug from a composite video monitor.
The PowerBook 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 3-14. Those picture resolutions produce underscanned displays on standard monitors.
