Can I connect a PC monitor to my mac?

Since two or more PCIe interfaces and dual core CPUs are getting more popular, high-end computer users no longer feel limited to two monitors driven off of one's main graphics adapter(s). It isn't all too uncommon to see users with three or even four monitors connected to a system with multiple graphics adapters. If dual PCIe interface is not available, a standard PCI graphics card can be used along with an PCIe or AGP card to extend to more than two monitors. Also some Matrox cards support more than two monitors with a single card.
