Some of the patterns are used to adjust contrast, brightness, sharpness color and tint, but others are simply to evaluate the capabilities of your HDTV. Not a big deal for us, but we admit it is personal preference. Now if you prefer to listen than to read, then bad news, as there are no audible directions. This works perfectly and is obviously designed by someone who uses a calibration disc a lot. The same pattern plays over and over again, so there's no hurry and when you're done you simply hit the right button to go to the next pattern. When you understand what the pattern is about, you simply hit down to dismiss the help and make your adjustments. Basically you select the pattern you want, or just select the first one, then hit the up button to see examples of what to look for and an explanation. In addition to the insert with very detailed explanations, there is also a help page on every pattern. We really appreciated the new approach to explaining how to use the disc. Speaking of which, the calibration disc has more patterns then you'll ever know how to use or understand. It is without a doubt some of the best three minutes of HD quality footage we've ever seen and something you're going to want to watch over and over again as you calibrate your display. In fact the beautiful imagery makes us want to move to Seattle.

From the first second you insert the disc you're in awe over the sound quality of the intro, but then you see the first images appear and your jaw drops at the picture quality.
