What is HDR (High Dynamic Range), and how can you get it?

High Dynamic Range (HDR) is the hot topic in the TV world, with manufacturers and content creators alike suggesting it could bring noticeable leaps in picture performance. Nearly all midrange and high-end TVs for 2017 have HDR, and HDR content is becoming more common, both on streaming services like Netflix and Ultra HD Blu-ray disc.

What is HDR?

HDR stands for High Dynamic Range, and it is the next big thing in the video world, primarily when it comes to 4K TVs and 4K content. The term originates in photography, and refers to a technique that heightens a picture’s dynamic range – the contrast between the brightest whites and the darkest blacks. HDR expands the range of both contrast and color significantly. Bright parts of the image can get much brighter, so the image seems to have more “depth.” Colors get expanded to show more bright blues, greens, reds and everything in between.

TV HDR and Photo HDR

One of the most important things to know about HDR TVs is that TV HDR is not the same as photo HDR. These are two very different things.

TV HDR: Expanding the TV’s contrast ratio and color palette to offer a more realistic, natural image than what’s possible with today’s HDTVs.

Photo HDR: Combining multiple images with different exposures to create a single image that mimics a greater dynamic range.

HDR for TVs aims to show you a more realistic image, one with more contrast, brightness and color than before. An HDR photo isn’t “high dynamic range” in this sense. 

What HDR content is available?

HDR content is filmed or mastered in HDR–playing ordinary footage on an HDR TV alone won’t cut it. Amazon Prime Video was the first service to stream ‘HDR’ footage, but Netflix also has its fair share of HDR content. On top of that, there’s the Ultra HD Blu-ray format, which includes HDR10 in its base specification. 

How can you get HDR?

There are two parts of the HDR system: the TV and the source. So to view HDR content, first you need a HDR-compatible TV. Whether you’re after a television, a projector, a mobile phone or tablet, it needs to be HDR-compatible. Another source of HDR will be physical discs. Ultra HD Blu-ray is the latest physical disc format.
