Connect the green, blue and red plugs of one end of your component video cable to the matching plugs on your video source. For example, if the video source is a digital video recorder, find its three component video plugs on the back of the device. Connect the three colored plugs on the other end of the component video cable to the three matching plugs in the component-to-VGA converter. Plug the converter into the back of the projector. When shopping for a component-to-VGA converter, you’ll see a variety of types, some with HDMI or DVI in their names. This is because some types convert video signals into various digital formats. Look for one that has the words “component” and “VGA” in the name. You may also find converters that come bundled with component video cables, which you won’t need if you already own component cables.
