edition of this disc was recommended by the New York Times, Widescreen Review, Secrets of Home Theater and High Fidelity®, and many other print and online publications. The second edition adds even more features and patterns and sets a new bar for the term “state of the art.” The Spears & Munsil disc is the first (and at this time only) disc to offer stereoscopic patterns for calibrating and testing 3D televisions. It has audio level and phase tests created using the latest noise-shaping algorithms. And for the professional or advanced enthusiast it contains a complete set of patterns suitable for precisely calibrating contrast, grayscale, gamut, and other settings using test equipment.
