CNET Australia has published a video how-to on the subject of TV calibration. It's just over 5 minutes long, and features display calibration pro Aaron Rigg of Avical Australia talking you through 4 picture settings you can easily set at home. It's a followup to a TV calibration how-to video they ran earlier in the year.
