A guide to HDR on your Samsung TV

In TV terms, 4K and UHD (or Ultra HD) are more or less interchangeable. 4K TVs have an increased number of pixels, resulting in higher resolution (3840 x 2160, which is a significant step up from Full HD TVs at 1920 x 1080). 8K has four times the resolution of 4K Ultra HD (7680 x 4320 pixels). Due to this, 4K and 8K TVs display incredible detail.

HDR, short for High Dynamic Range, enhances the contrast between light and dark colors. It expands a TV's ability to display a wider range of brightness, resulting in deep blacks and vibrant whites. When HDR is combined with 4K or 8K resolutions, the TV's pixels and image quality surpass that of a Full HD TV.

HDR+ Mode will improve the picture quality even further by adjusting the color and brightness range, ensuring that SDR (Standard Dynamic Range) content will look like HDR content. It not only enhances SDR, but the HDR+ algorithm also enhances standard HDR content. This is done by increasing the level of contrast ratio to differentiate objects from the background, while depicting image details for an overall smoother picture.

The HDR+ feature was introduced with 2016 SUHD TVs, and is activated by default on 4K and 8K TVs. If needed, you can adjust the feature using the Settings menu.
