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 is not installed, follow the instructions in
Chapter 6 to install an option card. But first, check the
following table to make sure your display adapter card and
monitor are properly matched.

switches or jumpers on the card are set properly. For example,
you may need to change a setting to select color or
monochrome. See the documentation that came with your
monitor or video card for instructions.
If you install an EGA or VGA display adapter card or if you
install another type of card that you want to be the primary
display adapter, you must set jumper JP4 on the main system
board to disable the built-in VGA interface.
