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 alternate 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)
■ Composite video (televisions, camcorders, VCRs, and video
capture cards with composite-video-in jacks)
✎
Composite video devices can be connected to the system only
by using an optional docking device.
