High Dynamic Range (HDR) video is an display technology that expands the contrast and colour range of video content beyond what is achievable with standard dynamic range (SDR). HDR displays a wider range of luminance levels, allowing for more details in both bright highlights and dark shadows. This technology enhances the overall visual experience by providing a more lifelike and immersive representation of scenes. HDR is commonly associated with increased bit depth, wider colour gamuts, and advanced display technologies, offering viewers a more realistic and visually stunning portrayal of video content, particularly in terms of brightness, colour accuracy, and detail.
