Getting Started
Using external display devices
In the future you can change the display settings by pressing 
Fn + F5
, or by configuring the display properties settings.
Connecting an external monitor via the DisplayPort™
(Available on certain models.)
To connect a DisplayPort™-compatible monitor to your computer, 
read the directions that came with your monitor. 
Directing the display output when you turn on the computer
Once you have connected an external display device, you can 
choose to use the internal display only, the external device only, or 
both simultaneously. 
Some modes are only available with the appropriate device attached 
and turned on.
The quickest way to change the display output settings is to use the 
display hot key (
Fn + F5
):
1
Press 
Fn
 and 
F5
 simultaneously.
2
While holding down 
Fn
, press 
F5
 repeatedly until the setting 
you want takes effect. Briefly pause each time you press the 
F5
 
key to allow time for the display to change.
This hot key cycles through the settings in the following order 
(the last two options are available if an external monitor is 
connected):
Built-in display only
Built-in display and external monitor (simultaneously)
External monitor only
Built-in display and TV (or other external video device)
TV (or other external video device)
External monitor and TV
Built-in display and external monitor (extended mode)
