With 4K now firmly in place as the standard for most new TV's, high dynamic range, or HDR, video is starting to move from being an enthusiast curiosity to the next big thing in home media. HDR content looks vibrant, crisp and can be a bigger upgrade than 4K, but what's done to make those great images?
Part of the confusion is that HDR isn't one thing, it's at least 4 different technology standards being unevenly applied by about the same number of competing video formats. These video standards, with opaque names like Rec2020 and SMPTE 2084, build on dozens of previous standards, going back to black-and-white CRT televisions and the dawn of broadcast. In short, it's all kind of a mess.
