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 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. 2-4 Pointing Devices and Keyboard
