m If the PowerBook starts up with the display closed (called “docking mode”)
and an external monitor is attached, the PowerBook’s display does not turn
on and the display’s resolution (800 x 600) is not listed in the resolution
section of the Control Strip.
For complete instructions on adjusting the resolution for an external
monitor, see the “Monitors” topic area of Mac OS Guide, available in the
Guide (h) menu.

Apple monitors and VGA or SVGA monitors. To connect an Apple or Apple-
compatible monitor, you must use the adapter that came with the computer.
