Do you need a video card?

To use the Apple Multiple Scan 20 Display, you need compatible video circuitry built into your computer or a compatible video card installed in your computer. If you are unsure whether your computer has the appropriate built- in video capability, check with an Apple-authorized dealer or service provider.

If your computer does not have the video capability necessary to use this monitor, you need to purchase a video card. (Video cards are available from an Apple-authorized dealer or service provider.) Install the video card before you connect the monitor to your computer. To install a video card in one of the expansion slots inside your computer, see the manual that came with your computer or video card.

Using more than one monitor

If your computer has expansion slots, you can use the Apple Multiple Scan 20 Display with one or more additional monitors connected to your computer. You may need a video card for each additional monitor you are using. See the manuals that came with your computer for information on working with additional monitors.

Note: If you see screen flicker or other interference when you use more than one monitor, move the monitors further apart or set the monitors at an angle, so their screens are close and their back panels are farther apart.
