HDR means High Dynamic Range, and it is a technology that offers a richer, more colorful viewing experience on your screen. With HDR you see more detail both in the shadows and highlights of a scene. Due to HDR, you get a brighter, more vibrant, and more detailed picture compared to a standard display. HDR is excellent for immersive video experiences, including movies and games. Some people say that HDR improves the viewing experience more than the high 4K or 8K resolutions do. If you have a new PC with Windows 10 that has support for HDR, you can turn on this display technology.
