Adjusting Brightness
When the Dell™ computer is running on battery power, you can conserve power by setting the brightness to the lowest comfortable setting by pressing

The Dell QuickSet Brightness Meter shows the current brightness setting for the display. Right-click the icon in the taskbar to enable or disable the
Brightness Meter on the screen.
You can enable or disable the Brightness Meter from the QuickSet taskbar menu. When the meter is enabled, press the following keys to adjust brightness:
l Press and the up-arrow key to increase brightness on the integrated display only (not on an external monitor).
l Press and the down-arrow key to decrease brightness on the integrated display only (not on an external monitor).
For more information about QuickSet, right-click the icon in the taskbar and click Help.
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 to 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.
If you choose a resolution or color palette that is higher than the display supports, the settings adjust automatically to the closest possible setting.

NOTE: By default, the Brightness Meter appears in the lower-right corner of the display. You can click and drag the meter to a new location, and the
meter subsequently always appears at the new location.
NOTE: Brightness key combinations only affect the display on your portable computer, not monitors that you attach to your portable computer. If your

monitor does not change.
NOTE: Use only the Dell-installed video drivers, which are designed to offer the best performance with your Dell-installed operating system.
