Switching 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, pressing fn+f4 alternates the screen image from computer
display to monitor display to 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.
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, DVD players, VCRs, and video capture cards with S-Video-in
jacks)
●HDMI (televisions, camcorders, DVD players, VCRs, and video capture cards with HDMI ports)
●Composite video (televisions, camcorders, DVD players, VCRs, and video capture cards with
composite-video-in jacks)
NOTE: Composite video devices can be connected to the system only by using an optional
docking device or expansion product.
