Using the Screen control panel

You can also use the Screen control panel to adjust the level of

light on your screen.

1. Choose Control Panels from the Apple (K) menu.

2. Open the Screen control panel.

3. Drag the Screen Contrast slider to the right or left to

adjust the level of light.

The screen changes as you drag the slider.

S Important: Normally, use only the Screen Contrast control.

Don’t use the Screen Brightness control unless your screen

appears dark even when the Screen Contrast slider is all the

way to the right.

Saving energy

Your Macintosh comes with software that reduces the amount of

energy consumed when you are not using your computer. The

software allows you to set the screen to turn off after a period of

inactivity, the length of which you specify. The image on the

screen reappears when you move the mouse or press any letter or

number key on the keyboard. Because the screen needs to warm

up, it will take up to 15 seconds for the picture to reappear.

Tu rning off the screen conserves energy. It also protects the

screen from “burning in” images, which can occur if you leave an

unchanging image on the screen for many hours or days.

Drag the slider to adjust the contrast on

your screen.

You should only use the Brightness control if

your screen begins to appear dark after extended

computer use (two to three years).
