Using a Display Adapter Card
If you are using a non-VGA monitor, you’ll need to install a
display adapter (video) card in one of the computer’s option
slots before you can connect the monitor. (Your dealer may
have already installed the video card for you.)
If the video card has not yet been installed, you’ll need to
follow the instructions in Chapter 5 to install an option card.
But first, check the following table to make sure your display
adapter card and monitor are properly matched.

When you are installing the video card, check to make sure
any switches or jumpers on the card are set properly. For
example, you may need to change a switch setting to select
color or monochrome. See the documentation that came
with your monitor or video card for instructions.
Note
If you install a display adapter card, you must set jumper
J1 on the main system board to disable the built-in VGA
interface so that your card can operate as the primary
display adapter. You may also need to set jumper J3 to
indicate whether a color or monochrome monitor is
installed. See Chapter 5 for instructions on changing
jumper settings.
