Using a Display Adapter Card

If you are not using a VGA monitor or if you want to install an optional display adapter card instead of using the built-in adapter to control your VGA monitor, read the guidelines in this section.

Before you can connect a monitor to a display adapter card, you must install the card in your computer. If it is not already installed, follow the instructions on page 2-16 to install an option card.

When installing the card, make sure any switches or jumpers on the card are set properly. For example, you may need to change a switch setting to select the refresh rate. See the documentation that came with your monitor and display adapter card for instructions.

If you install an optional display adapter card, you must set jumper J6 on the main system board to position 2-3 to disable the built-in VGA port. (You do not have to do this if you connected the card to the VGA feature connector on the main system board.) You also need to set jumper J5 to the On position if you are using a CGA adapter and monitor. See page 2-6 for instructions on changing jumper settings.

Note

If you install a high-resolution graphics adapter card that connects to an alternate VGA interface (also called a “feature connector”), see page 2-26 for instructions on connecting the card to the connector on the main system board.

After you install the card, connect your monitor to the computer. If your monitor came with its own manual, follow the instructions there. Otherwise, just insert your monitor connector into the adapter card port instead of the built-in port.
