Brightness Meter
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.
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:
Press
to increase brightness on the integrated display only (not on an external monitor).
Press
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
to switch the video image to the display only, the external device only, or the display and the external
device simultaneously.
