White Paper: Elements of High Dynamic Range Video
Over the past seven decades, display technology has progressed to the point where 4K/Ultra HD video is now the gold standard. 4K resolution yields four times the number of pixels as HD video, but depending upon the size of the display and the viewing distance, there may be no perceptible difference between an HD image and a 4K/UHD image. Adding HDR - High Dynamic Range to a 4K/UHD image is the differentiator that takes 4K/UHD far beyond what HD can offer. HDR enhances the quality, rather than the quantity, of the pixels being displayed since it provides richer colors and greater contrast.
