Apple PowerBook (3400 series) - Manual (Page 68)

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.
Your PowerBook has an external monitor port to which you can connect most
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.
The list below shows a sampling of the external monitors and resolutions
supported by your PowerBook. Many other monitors are also supported.
