TOPIC

    This article contains important information and specifications for the 128-Bit 2D/3D Professional Graphics Card option for Power Macintosh G3 computers.

DISCUSSION

    If your computer came with an additional graphics card, you have the following options for connecting an external monitor to your computer.
    • Connect an external monitor to the built-in monitor port (shown in the manual that came with your computer).
    • Connect an external monitor to the graphics card installed in one of the PCI slots. There are two ports on the optional graphics card. One is the type found on the back of most Macintosh computers; the other is a VGA port so you do not need an adapter for a VGA monitor.

      Note: You cannot use both ports on the optional graphics card at the same time.

    • Connect two external monitors to your computer. You can connect one monitor to the built-in monitor port and the other monitor to one of the ports on the graphics card installed in one of the PCI slots.
