

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.

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 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 video controller 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 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 connected to an external monitor and you try to change the brightness level, the Brightness Meter appears, but the

brightness level on the monitor does not change.
