When connecting typical audio/video equipment together you usually use an RCA connection. RCA has three cables, a yellow cable for the video and red and white cables for the audio. However, even though a computer monitor deals with video it connects to a computer by either a VGA or DVI cable. If you want to connect a computer monitor to a traditional audio/video device you need to convert the PC monitors to the video RCA plug (the yellow cable).
Look on the back of the PC monitor and identify what kind of port is used on the computer. A DVI port has a series of square insert ports with a cross shaped port next to it. A VGA port has a series of circular pin insert points lined up in three rows.
Plug either a DVI to RCA or VGA to RCA adapter into the available port on the PC monitor.
Thread the tightening screws on the side of the DVI or VGA monitor cable. These screws turn clockwise and you can hand-tighten them. This creates a secure connection between the cable and the monitor and insures the cable will not fall out of the monitor.
Plug the yellow RCA cable into the "Video Out" port on the device you want to connect to the PC monitor. This can range from a DVD player to a video game system.
Power on the video device and monitor. Once the monitor warms up you should be able to see the contents of the video device over the PC monitor.
