A PCI Video Card

This is a picture of a PCI video card.

Display systems are relatively the same. They all work on the same theory. When the computer wishes to output a picture on the monitor, it sends the instructions to the video card. The video card is generally an expansion board installed in an expansion slot on the motherboard. The video card interprets the command sent to it and begins "rendering" the picture into multiple instructions. The new instructions are sent to the monitor, which displays the picture. 

The major difference encountered in display systems is the formatting used by the video card.
