We’ve been using some of the excellent tools available in a beta version of the disc for the past few months and have found things like the moving star field pattern (great for evaluating blooming and dark shadow detail, and showing off the merits of self-emissive displays against black-lit ones), a local dimming zone counter (great for determining areas with weak control spots in LED LCD TVs with full-array backlighting) and color banding (quantization) moving test patterns that we now find indispensable in testing and evaluating a 4K television’s ability to render lifelike color transitions in backgrounds like the sky or underwater. It provides one of the most comprehensive collections of test patterns and sample imagery yet available for 4K Ultra HD and HDR in a disc format. The Spears & Munsil Hand Forged Video UHD HDR Benchmark Disc ($39.95) was developed for home theater novices and professional calibrators, alike. The good news is that the tandem has finally released their first 4K Ultra HD/HDR 4K Blu-ray version to home users. Anyone interested in getting the proper performance out of a modern television set will be familiar with the excellent series of Hand Forged Video Bench Mark calibration discs from experts Spears & Munsil.
