Samsung TV - What is HDR?
If you’ve been thinking about getting yourself a 4K TV, a 8K TV or HDR video compatible TV, you’ve no doubt met some confusing, possibly even conflicting information along the way. We hope that this information will help to clarify exactly what the differences between the technologies are and why HDR+ is the standard that should be preferred.
The provided information refers to TVs sold in Canada. The available settings and options may differ for devices sold in other countries.
In the TV world, 4K and UHD (or Ultra HD) are more or less interchangeable terms. 4K TVs have a greatly increased number of pixels in their screen, resulting in higher resolution, 3840 x 2160, a significant step up from Full HD TV at 1920 x 1080. 8K is a resolution of 7680 x 4320 pixels, four times the resolution of 4K Ultra HD. 4K and 8K TVs with all those extra pixels definitely show much greater detail but the next step in enhancing images for 4K or 8K resolution is to address the all-important issues of contrast ratio. And that’s where HDR technology steps in.
HDR is an acronym for ‘High Dynamic Range’. This is really all about the expression of images and is a result of the depth of contrast between light and dark colors that a TV screen can produce. Or as the name directly states, the range of luminance that a television screen is able to render (blacks look really deeply dark and whites vibrantly bright). So when you combine 4K or 8K resolution and HDR in one TV you get a powerful package—pixels to boot and the ability to produce optimized images of quality far beyond a Full HD TV.
The HDR+ Mode will improve your picture quality even further by adjusting the color and brightness range, ensuring that your standard dynamic range (SDR) content will look like HDR content. In fact, it not only enhances SDR, the HDR+ algorithm also enhances standard HDR content increasing the level of contrast ratio to differentiate objects from the background, while still depicting more image details on the screen for an overall better picture.
The HDR+ feature was introduced with 2016 SUHD TV and is activated by default with 4K and 8K TV. You can find HDR+ in the settings menu under: Settings > Picture > Special Viewing Mode > HDR+ Mode.
