The abbreviation HDR applied to the TV was met by many. But not everything is known about what it is like. HDR stands for High Dynamic Range or "Extended Dynamic Range". This technology is implemented in the latest generation TVs. It involves highlighting various sections of the screen in order to make the light elements even lighter, and dark - darker.

Advantages of HDR

The difference is obvious

HDR technology stands out from the old dynamic range (SDR or Standard Dynamyc Range), as it provides unrivaled image quality. Images on the screen look more contrasting, more voluminous and realistic than with SDR, and the base colors (blue, red, green) form a wider range of derived colors and shades.

With HDR technology, blue gets more shades

HDR Formats

HDR10

This format is supported on all HDR TVs and 4K Blu-ray players. Has the same characteristics as the UHD Premium standard. There is an improved version of HDR10, known as HDR10 +. It adds dynamic display of tones, as in Dolby Vision.

The improved version of HDR10 is almost indistinguishable from Dolby Vision

Dolby Vision

The Dolby Vision format is the most advanced version of HDR. For the first time it was presented in TVs of the South Korean company LG Electronics. The advantage of the format is an increased number of reproducible colors and shades, a drawback is the lack of content.

Dolby Vision - advanced format

HDR on the TV screen and in the smartphone: the main differences

The HDR technology on the TV screen differs from the HDR effect in a smartphone or camera. Photographers with the help of this effect from several simple pictures of the same object create an aggregated photo with an imitation of the extended dynamic range. On television, everything happens differently. All materials are immediately shot in HDR format, due to which the realism of images is significantly increased. No additional software processing is required here.

Thus, HDR technology is a real trend of the present. It maximizes the image on the TV screen to the real picture by improving the quality of pixels.
