HDR, short for high dynamic range, is one of the most sought-after features in high-end monitors. Without getting too deep into it, HDR means a monitor can display a wider range of brightness levels while retaining visible detail. The way monitors usually work means that you have to choose between blowing out the highlights or losing all details in the shadows, but with HDR, you can enjoy these kinds of scenes with full detail, which makes for a much better experience watching movies or even playing games on a gaming PC.
