Using external display devices
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):
1While holding down Fn, press F5 repeatedly, pausing between
each press, until the setting you want takes effect.
This hot key cycles through the settings in the following order:
Built-in display only
Built-in display and external monitor simultaneously
External monitor only
TV (or other external video device) only
External monitor and TV simultaneously
Built-in display and TV (or other external video device)
simultaneously
Built-in display and external monitor (extended desktop)
Built-in display and TV (extended desktop)
External monitor and TV (extended desktop)
Swap-Switch primary display between internal display
and external monitor when using extended desktop
