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

. 

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 <Fn> and the up-arrow key to increase brightness on the integrated display only (not on an external monitor). 

 

l

 

Press <Fn> 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. 

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 
display or the external device. 

Press <Fn><F8> to switch the video image to the integrated display only, the integrated display and an external CRT monitor simultaneously, an external CRT 
monitor only, the integrated display and external DVI monitor simultaneously, and external DVI monitor only. 

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. 

If the video resolution setting is higher than that supported by the display, the computer enters pan mode. In pan mode, the screen cannot be completely 
displayed. For example, the taskbar that usually appears at the bottom of the desktop may no longer be visible. To view the rest of the screen, use the touch 
pad or track stick to pan up, down, left, and right.

Brightness Meter 

 

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.

 

Brightness keyboard shortcuts only affect the display on your portable computer, not monitors that you attach to your portable computer or 

docking device. If your computer is in CRT only mode and you try to change the brightness level, the Brightness Meter appears, but the brightness level 
on the monitor does not change.

 

Use only the Dell-installed video drivers, which are designed to offer the best performance with your Dell-installed operating system.

 

As the resolution increases, icons and text appear smaller on the screen.
