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 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 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

If you choose a resolution or color palette that is higher than the display supports, the settings adjust
automatically to the closest supported values.
