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.
