Connecting a Second Monitor
You can install an expansion card that provides a second monitor port, if one monitor doesn’t provide enough screen space.
To connect a second monitor, purchase a video card and install it in one of the computer’s PCI expansion slots, or have an Apple dealer install it for you. (If you are installing the expansion card yourself, follow the instructions that came with the card and the instructions in Chapter 3.) Then connect the second monitor to the port provided by the card.
Make sure that the ventilation openings on the monitors are clear and unobstructed. If there is interference on your screens or on a television or radio near your computer, separate or reposition the affected equipment. You may need to move the monitors farther apart so that they don’t interfere with each other.
For additional instructions on using two monitors together, open Mac OS Help (available in the Help menu) after you have connected both monitors to your computer; click the Index button, and choose “monitors” from the index.

Before you attach or remove an ADB device, turn off the computer. Attaching or removing an ADB device while the computer is turned on could damage the ADB device or your computer.
Important The total current used by all ADB devices connected to your computer must not exceed 500 milliamperes (mA). Before attaching another ADB device, check the Technical Information booklet that came with your computer and the information that came with the ADB device for power requirements.
