Adjusting Brightness
When the computer is running on battery power, you can conserve power by setting the brightness control
to the lowest comfortable setting using the appropriate
display keyboard shortcuts .
Switching the Video Image
You can use the keyboard shortcut to switch the video image to the display only, the display
and external monitor simultaneously, or the external monitor only.
NOTE: only works with CRT monitors, not with composite/S-video monitors.
If the external monitor is turned off when you boot your computer, the computer still sends the video image
to the external monitor, but you will not see an image on either the computer display or the external
monitor. To see an image, turn on the external monitor or switch the video image to the computer display.
Setting Display Resolution
To display a program at a specific resolution, both the video controller and display must support the program
and the necessary video drivers must be installed.
