This article documents the supported resolutions available for an external display connected to the PowerBook G3 Series (Bronze keyboard) and PowerBook (FireWire).
DISCUSSION
The PowerBook has a video out port that allows you to directly connect a monitor with a VGA-style adapter, or other external video device such as a video projector. If you have an older Macintosh-compatible monitor, you can connect it using the VGA-to-Macintosh video adapter that came with your computer.
When an external monitor is connected, you can either have the same image appear on both the internal display and the external monitor (known as video mirroring) or use the external monitor to extend the size of the Mac OS desktop (known as dual display mode).
The supported resolutions for external displays are as follows:

+ Millions of colors are only available on the external monitor when the PowerBook display is closed, dedicating all 8MB of video memory for the external display.
Playback of DVD movies on a television connected to the PowerBook (FireWire) reduces the amount of video memory available for the built-in display. You may have fewer colors available at higher resolutions.
TV out supported resolutions
The TV out port (also known as an S-Video out port) on your computer lets you connect to a television, videocassette recorder (VCR), or video projection system.

You can use TV out to display images on a television or record computer images on a VCR. If your computer came with a DVD-ROM drive, you can use it to play DVD discs on your television.
When an external video device is connected to the TV out port, you can either have the same image appear on both the internal display and the device ("video mirroring") or you can use the device to extend the size of the Mac OS desktop ("dual display mode").
Because of the display limitations of most televisions, images displayed on the television screen are of lower quality than those on the built-in display or an external monitor.
How you connect video equipment to your computer depends on the type of equipment you want to connect. The S-video port can output the following display formats:
S-video: High-quality video format used by certain televisions, VCRs, and video projectors

You can connect a cable from a S-video device directly to the S-video output port on the computer. S-video is recommended because it provides better quality than standard composite video cables.

To connect a composite video device, you need to use a composite video cable (not included with the PowerBook) and the composite to S-video adapter that came with your PowerBook. (Shown below)

Use the TV Mirroring portion of the Control Strip to turn video mirroring on and adjust the settings for how the images are displayed on the television.
