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.
