Using the Display
Adjusting Brightness
When a Dell™ computer is running on battery power, you can conserve power
by setting the brightness to the lowest comfortable setting by pressing <Fn>
and the up- or down-arrow key on the keyboard.
Switching the Video Image
When you start the computer with an external device (such as an external
monitor or projector) attached and turned on, the image may appear on
either the computer display or the external device.
Press <Fn><F8> to switch the video image between the display only, the
external device only, or the display and the external device simultaneously.
Setting Display Resolution
To display a program at a specific resolution, both the graphics card and the
display must support the program, and the necessary video drivers must be
installed.
Before you change any of the default display settings, make a note of the
default settings for future reference.
NOTE: Use only the Dell-installed video drivers, which are designed to offer the
best performance with your Dell-installed operating system.
If you choose a resolution or color palette that is higher than the display
supports, the settings adjust automatically to the closest supported values.
