Switch Image (fn+f4)
The fn+f4 hotkey switches the image among display devices
connected to the system. For example, if an optional monitor
is
connected to the notebook through the monitor port, each time
you press the
fn+f4 hotkey the image will switch among the
notebook display, the monitor display, and a simultaneous display
on both the notebook and the monitor.
Most monitors receive video information from the notebook
using the external VGA video standard. The
fn+f4 hotkey can also
toggle images among other devices receiving video information
from the notebook.
The following video transmission types, with examples of devices
that use them, are supported by the
fn+f4 hotkey:
■ LCD (notebook display)
■ External VGA (most monitors)
■ S-Video (televisions, camcorders, VCRs, and video capture
boards with S-Video–in jacks)
■ Composite video (televisions, camcorders, VCRs, and video
capture boards with composite video-in jacks)
