20 Chapter 2

What happens after you turn on the energy-saving feature

When Energy Saver is on, the monitor ???goes to sleep??? after a specified period of inactivity. The monitor screen looks dark and the monitor is using less energy. When the monitor is asleep, your computer is still working. But to prevent accidental changes, you can???t make any changes while the monitor is asleep.

To ???wake up??? the monitor, move the mouse or press any key on the keyboard. Your computer beeps while the monitor is waking up. The process takes about 20 seconds, and you can begin work as soon as the computer stops beeping. (The beep volume cannot be adjusted; it is not controlled by the computer???s sound software.)

IMPORTANT The Energy Saver control panel works with Apple monitors (such as this one) that comply with the EPA???s Energy Star program and any other monitor that complies with the Video Electronics Standards Association???s Display Power Management Standard (VESA DPMS). Your computer model must also be compatible with Energy Star. Other monitors will darken after the specified inactivity period, but they won???t go to sleep or save energy.

Using Energy Saver with a screen saver

???Screen saver??? programs darken the screen or display a changing image on the monitor if the computer is not used for prolonged periods. Both screen saver programs and the Energy Saver feature prevent images from ???burning in??? and damaging the screen. Energy Saver also conserves energy.

If you wish, you can use both Energy Saver and a screen saver program. Set the screen saver to come on before Energy Saver, so if you???re away from the computer for a short while, you can return to work immediately, without waiting for the monitor to wake up. If you???re gone for a while longer, however, the monitor won???t use as much energy.

Using ColorSync

ColorSync is Apple???s unique color-matching software that ensures that Apple color printers print the best possible reproduction of the colors that appear on your monitor screen. ColorSync is also used by Apple color scanners and the QuickTake camera to capture color images and accurately reproduce their colors on the screen. ColorSync maintains consistent colors between color input, your monitor, and color printing devices so that the colors of your original image are accurately reproduced on screen and when printed.

The ColorSync software works automatically in the background. When you install the display software, your computer is automatically set to use ColorSync with your monitor.

If you use more than one color monitor with your Macintosh and want to print a color image from a specific monitor, you can obtain the best color matching by setting ColorSync to use a specific monitor.

To set up ColorSync for a specific monitor:

mCheck whether something is plugged into the sound output port (marked by -) on the back panel of your computer. The computer???s internal speaker is turned off whenever a cable is connected to the sound output port. If a sound cable is connected between the computer and monitor, you

can hear sound from the monitor???s speakers or from headphones connected to the monitor???s headphone port (marked by f). For more information, see Chapter 1, ???Setting Up.???

You can???t find the Control Strip.

mYou may have hidden the Control Strip. Open the Control Strip control panel and click the button labeled Show Control Strip.

You can???t control the sound volume of a CD.

mThe volume control on the Control Strip affects the computer???s beep sound

only. To control the volume of a CD, use the AppleCD Audio Player, located in the Apple (K) menu.

You don???t see the monitor resolution you want.

You can see additional resolution choices in the Monitors control panel if you hold down the Option key on your keyboard while you click the Options button in the control panel. In the list that appears, click the resolution you want. (Some models use a different control panel. Consult the documentation that came with your computer or system software upgrade kit.)

Note: Some of the items in this list are not optimized for your monitor. If you choose a resolution that doesn???t work with your monitor, you may see a message, or your monitor may go blank or show static. After approximately 15 seconds, your monitor should revert to a usable resolution. If it does not, restart your computer.

After you change the screen resolution, a window is stuck, halfway off the screen, or missing; or you can???t see the whole screen.

Try one of the following:

mIf you changed the resolution in a control panel, make sure the control panel is closed before trying to use another window.

mQuit the program whose window is missing and then open it again.

mIf the program has a Windows menu, use it to hide the problem window and then show it again.

mGo back to the resolution you were using, close the window, change the resolution, and then reopen the window.

mTry another resolution.

If you have problems with a particular program, contact the publisher of that program. Not all programs take advantage of your monitor???s multiple resolution feature.

After you change the number of colors displayed on the screen, the colors don???t look right.

Try one of the following:

mQuit the program you???re running and start it again.

mGo back to the number of colors you were using.

After you change the screen resolution, icons move.

Changing the screen resolution affects how information can be displayed on your screen. The display software may automatically reposition icons after you change the screen resolution.

After you attached a new monitor to your computer, the new monitor???s screen is blank or shows ???garbage??? or ???snow.???

The computer may not have recognized the monitor. Try the following: Turn off the computer and disconnect the new monitor. Start the computer with no monitor attached. Wait a minute or so for the computer to finish turning itself on. Turn off the computer again and reattach the new monitor.

The monitor does not go to sleep.

Some computers and video cards do not support the Energy Saver feature. See the documentation that came with your computer and video card for more information.

If you have a Power Macintosh 9500, you can get an upgrade to your software that allows your monitor to work with Energy Saver. Call the Apple Service and Support number found in the service and support information that came with your computer.

When you use both Energy Saver and a screen saver program, the screen freezes.

The screen saver program may be conflicting with Energy Saver. Turn off either the screen saver program or the Energy Saver control panel.

You see two resolution options labeled 640x870 (75 Hz).

If you???re using the Macintosh 24AC video card, you may see two apparently identical resolution selections. The first option sets your monitor to display millions of colors, and the second option sets your monitor to display 256 colors.

When you change resolutions, the monitor goes blank.

If your monitor is connected to the Macintosh 24AC video card, the monitor may go blank for 15 seconds when you select a resolution that does not work with your monitor. Try selecting another resolution.
