Switching the Video Image

Setting Display Resolution
To display a program at a specific resolution, both the video adapter and the display must support the program, and the necessary video drivers must be
installed.
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 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.
NOTE:
You cannot switch the video image when using extended desktop mode.
