Monitors and Picture Sizes

With the included adapter, the PowerBook computer can be used with any Apple monitor, including the AV monitors, the 17-inch and 20-inch multiple scan monitors, and Apple Studio Displays (except those that have only a DVI connector). The computer also supports VGA, SVGA, and XGA monitors. Table 3-11 lists the picture sizes and frame rates supported.

The computer includes 8 MB of video memory, which is enough to provide pixel depths up to 24 bits per pixel on all supported monitors when the flat panel display is inactive (display closed). When an external video monitor and the flat panel display are operating at the same time, half the video memory is available for each. In that case, the maximum pixel depth available on the external monitor at the 1280-by-960 and 1280-by-1024 picture sizes is only 16 bpp.
