HDR stands for High Dynamic Range. That is a rather vague term that doesn’t say anything much about its purpose.

But HDR for 4K HDTV is all about colour quality enhancement. With the HDR feature you get far superior color quality than that of non-HDR TV.

In an HDR HDTV you get better brighter highlights and color detail with HDR than without it.

How HDR Works

HDR works by improving on color contrast and colour accuracy of a picture.

Color contrast is improved when the bright parts of a picture is made brighter to lend more depth to the picture. The dark parts of the picture are made deeper darks for increased contrast.

What’s the Difference Between HDR and HDR10?

There’s no difference between HDR and HDR10. When we refer to a HDR in an HDTV, we mean it supports HDR10.

So, if your HDTV says it supports HDR, it means HDR10 is supported.

Some HDTVs models call HDR by another name. LG for instance calls it HDR Pro.

WCG Feature

HDR usually comes with the WCG (Wide Colour Gamut) feature. Basically, it allows an HDR TV to produce more colours than it is capable of.

What You Need to Enjoy HDR

  1. You would need a 4K HDTV which supports HDR. Not all 4K TVs support HDR.
  2. The content you wish to screen on your TV must also be of the HDR type.
  3. You would need an HDMI 2.0a connection to watch HDR content.

HDR Content Availability

HDR for HDTV content is rather limited as of now.

HDR content is available with UHD (4K) Blu-ray discs.

Streaming services like Netflix, Amazon and Vudu support HDR through their 4K content.
