Note: You may also need to purchase an adapter to connect the display cable to the
graphics card on your computer.
Macintosh computers come with two possible display ports: Apple Display Connector
(ADC) ports to connect ADC displays, and Digital Visual Interface (DVI) ports to connect
digital displays that have DVI connectors (such as a flat-panel Apple Cinema Display).
 If your second display is an ADC display: Connect it to an available ADC display port on
your computer, or use a DVI to ADC adapter to connect the display to a DVI display port.
 If your second display is a DVI display: Connect the display to an available DVI display
port on your computer, or use an ADC to DVI adapter to connect the display to an
ADC display port.
See the documentation that came with your computer or graphics card for more
information about the type of display cable or adapter you need.
To connect a second display to your computer:
1
Turn off the computer.
2
Connect a display cable (and adapter, if necessary) from an available display port on
your computer or graphics card to the display.
Depending on your displays, you may have one or more cables to connect. Refer to the
documentation that came with the display and your computer for detailed information.
Important:
Make sure the cables are connected firmly, or you may not be able to see
an image on the display.
