Connecting More Than One Monitor

I know my computer has two video-out ports but I can only run one monitor at a time from either port. What do I need to do to get my computer to run two monitors at the same time?

The built-in video that runs the two ports (one Apple DB-15 and one VGA) is the same video RAM on the Logic Board so it cannot be divided to run one monitor per port. To run a second monitor requires a PCI-based video-out card which comes complete with its own Video RAM and video-out ports. As long as the card is PCI 2.0 compliant (the standard it must meet), the card should work. Old NuBus video-out cards WILL NOT WORK.

Machines Affected: All PCI-based models
