In a few cases, we’ve had to create our own format, because no existing file format could represent the pattern we needed to create.” If a pattern needs to be generated directly in a very specific color space and data format, we generate it in that color space and format we’re not limited to what you can do with off-the-shelf graphics software. We believe this disc completely changes the game for test and evaluation discs, by making use of all of the features and range that HDR and wide-gamut standards can offer.”ĭon Munsil adds: “We build every pattern using our own tools, written from scratch in C++. Nearly every pattern is encoded in multiple versions, with metadata and peak levels adjusted for a wide variety of HDR display technologies including 600, 1,000, 2,000, 4,000, and 10,000 nits.Īccording to Stacey Spears: “Every pattern has been rethought with High Dynamic Range and Ultra HD in mind. And while many of the disc’s offerings are crafted for professional calibrators, included material will also appeal to casual users hoping to squeeze more performance from their preferred TV. Years in the making and long-rumored, this is the reference-grade 4K UHD test disc that enthusiasts and pro calibrators have been asking for.īorn from the incredible success of both DVD and standard Blu-ray versions of the disc, Stacey Spears and Don Munsil have re-joined forces to unleash more features and patterns to dial-in and evaluate today’s high-test 4K displays. The highly anticipated Spears and Munsil UHD HDR Benchmark Disc ($39.95) has finally launched. (July 1, 2019) Here’s a bit of rather exciting news.
