Directing the display output when you turn on the computer
Once you’ve connected an external display device, you can
choose to use the internal display only, the external device
only, or both simultaneously. 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.
This hot key cycles through the settings in the following
order:
❖ Built-in display panel only
❖ Built-in display panel and external monitor
simultaneously
❖ External monitor only
3 Release the Fn key.
TECHNICAL NOTE: You can also change these settings using the
Display Properties Box.
Adjusting the quality of the external display
To obtain the best picture quality from your external display
device, you may need to adjust the video settings. See the
documentation supplied with the device for additional
configuration steps.
TECHNICAL NOTE: In order to use the simultaneous mode, you
must set the resolution of the internal display panel to match the
resolution of the external display device. The external display
device must support a resolution of 640 X 480 or higher.
