For the past three years or so, we have seen a tremendous surge in display technology. During this time, the last rites for the venerable CRT have been read, 50" displays have become the new 32", and 1080p has become the de facto standard for resolution. One thing hasn't changed however and that is the need for precise calibration of your HDTV. Despite tremendous advances in consumer displays, the specifications for color, grayscale, and gamma have not changed since the 1950s. With all these new features available, it has become more confusing than ever for the typical home theater enthusiast to achieve a correct calibration and realize the best performance from your flat panel or projector HDTV.
