In this video from lunawebs we learn how to use an external monitor with a camcorder. The best way is to use an HDTV and use your HDMI output on the TV. The sound can also come through the monitor if you have a headphone port on the monitor. If you want to go outdoors, it will be more of a challenge. If you do not have an HDMI out on your camera, there is a component you can use. Composite AV outs are cheaper when it comes to monitors and camcorders. If you have a composite monitor, assign the camera to use the audio video from a headphone jack port. Now plug into the headphone jack on the monitor with your headphones to monitor your sound.
