An HDR TV is showing every detail on the TV screen with HDR images by displaying an ocean shore scene with the sun rising in the horizon as seen from within a cave opening.

What does HDR mean?

HDR stands for High Dynamic Range and refers to a technique that expresses details in content in both very bright and very dark scenes. It offers a more natural and realistic picture output even with a widened range of contrast. For example, in a very dark cave scene, HDR TVs show the appearance and colour of the cave walls as well as its texture. And in a scene with a yacht on the ocean, individual sunbeams are clearly seen shining regardless of the bright sunlit background. You're probably reading this article from your computer screen or mobile phone right now and if your device doesn't support HDR, you're missing out on the full experience and understanding of what HDR can really do. So do yourself a favor and visit your nearest electronics store and experience HDR TV quality for yourself because seeing is believing.

A TV marked with "HDR" is displaying the beach sunset image with High Dynamic Range.
A video of the ocean shore at sunset starts in Standard Dynamic Range. Then the video switches to High Dynamic Range, HDR, which shows the scene brightly and vividly coloured.

Types of HDR

There are various kinds of HDR standards, but 'HDR10' is the most commonly used. Recently, a new technology called HDR10+ has been introduced, and the difference between that and HDR10 is whether dynamic metadata* or static metadata is used. Dynamic HDR technology means applying metadata to each scene, and then delivering a more optimised picture quality compared to that of static HDR technology.

* Metadata refers to the additional image information found within content. This includes the coloUr and brightness information used in the HDR image mastering process.
Photos show differences between HDR10+ and HDR10. The photos with HDR10+ shows 'Better color saturation' and 'Balanced brightness', but the other photos with HDR10 displays 'Slightly under-saturated' and 'Unbalanced brightness'.
