XDR

 XDR stands for eXtended Dynamic Range. It is a technology that is used to expand the dynamic range of a display, which is the difference between the brightest and darkest parts of an image that can be displayed on a screen.

XDR is an improvement over HDR (High Dynamic Range) technology, which already offers a wider range of brightness levels than standard imaging. XDR takes this a step further by enabling displays to achieve even higher levels of brightness and contrast, resulting in images that are more vibrant and realistic.

One of the most well-known XDR technologies is Apple's Pro Display XDR, which features a peak brightness of 1600 nits, compared to the 1000 nits of most HDR displays. XDR technology is also used in high-end professional displays and televisions from other manufacturers.

XDR technology is achieved through a combination of hardware and software enhancements, such as the use of more powerful LED backlights, improved color processing, and advanced algorithms for tone mapping and local dimming. The result is a display that is capable of reproducing a wider range of colors and brightness levels, making images and videos look more lifelike and immersive.
