Pointing Devices and Keyboard

Switch the screen image (fn+f4)
Press fn+f4 to switch the screen image among display devices connected to the system. For example,
if a monitor is connected to the computer, each time you press fn+f4 the image switches among the
computer display, the monitor display, and a simultaneous display on both the computer and the
monitor.
Most external monitors receive video information from the computer using the external VGA video
standard. The fn+f4 hotkey can also toggle images among other devices receiving video information
from the computer, such as S-Video.
The following video transmission types, with examples of devices that use them, are supported by
the fn+f4 hotkey:
●
LCD (computer display)
●
External VGA (most external monitors)
●
S-Video (televisions, camcorders, VCRs, and video capture cards with S-Video-in jacks, on select
models)

in jacks)
NOTE Composite video devices can be connected to the system only by using an optional
docking device.
