22 Chapter 2 The Basics
Adjusting Your Display
Once you begin working with your new PowerBook, you may need to adjust your
display so that the screen is easier to see. Use the keys labeled with the ¤ icon to
adjust screen brightness.
To turn off the automatic display brightness feature:
m Choose Apple () > System Preferences from the menu bar. Open the Displays pane
and deselect the automatic brightness checkbox.
Changing the Size of Images on the Screen
Your PowerBook has a wide-screen display with a native resolution of 1440 x 900. You
can use other standard resolutions, such as 1024 x 768, as well.
Use a standard resolution when mirroring your screen on an external monitor or when
using applications such as games or presentation software designed for a standard
resolution.
When you use a standard resolution, a black band appears on each side of the display.
If you do not want to see the black bands, you can choose a “stretched” version of the
resolution to stretch the image to cover the entire screen and eliminate the black
bands.
