HDRIntro

HDR (High Dynamic Range) is a technology supported in higher-end 4K devices that helps to expand the range of both contrast and color significantly. Bright parts of the image can get much brighter with better color accuracy, while dark parts of the image can get much darker improving the contrast. Overall, the image has a greater "depth". HDR is not strictly a 4K-only technology, but today’s HDR TVs are largely also 4K TVs.
