What is dynamic range in television?
Dynamic range in television refers to the difference between the darkest black and the brightest white that a display can produce. It is essential for delivering a more immersive and realistic viewing experience. A wider dynamic range allows for greater detail in both the highlights and shadows of an image, making scenes appear more lifelike and adding depth to the viewing experience.
In practical terms, dynamic range is often quantified in terms of nits, which measure brightness, and refers to the contrast ratio between the brightest and darkest parts of an image. High dynamic range (HDR) technology has become a standard in modern televisions, allowing for a more extensive range of brightness levels compared to standard dynamic range (SDR) displays. This innovation enhances the depth and realism of content, bringing out subtle details that would otherwise be missed.
What is the difference between HDR and SDR?
HDR, or High Dynamic Range, enhances the brightness and contrast of images significantly compared to SDR, or Standard Dynamic Range. HDR content is designed to take full advantage of newer display technologies that are capable of producing brighter highlights and deeper blacks.
