HDR Technology & Dolby Vision in LED Television Explained


It is the era of modern technology and the technology is improving at a tremendous rate. New technologies are inventing day by day like it seems that we have recently seen the advent of the Full HD TV, when we have the Ultra HD or 4K TV available in the market.

Since the introduction of new technology HDR, barely has the 4K TV settled down. This has virtually redefined the way you watch TV. HDR, or High-Dynamic Range, is the most common and must have TV features now. TVs that support HDR can usually provide brighter highlights and a wider range of color details and gives you to have a new experience of watching TV. 

Dolby Vision is another aspect of new generation LED televisions. Dolby Vision is basically a proprietary, dynamic HDR format which is developed by Dolby Labs. It provides you to see TV with better color accuracy by adjusting the picture on a scene-by-scene and even frame-by-frame basis. 

To know what HDR actually is and what is the advantages of having it on TV along with to get information about dolby vision, explore the article. We are going to provide you with the details of these aspects. 


HDR TechnologyHDR means High Dynamic Range. HDR technology is just like human eyesight. If you have a look at the blue sky on a sunny day, you will be able to distinguish between the different layers of white clouds by enjoying the scenery. 

Now, have a look at the same scene on a 4K TV screen. Definitely  you will be able to look at the blue sky as well as the white clouds. But, it would be difficult to make a difference between the layers of the clouds. Thus you see that technology for all its brilliance is still inferior to the human eye. HDR is invented to change this concept.

HDR technology is mainly a borrowed term from photography. This technique works to highlight the contrasts and  differences between the brightest of whites and the darkest of blacks. HDR increases the range of both color and contrasts significantly. Bright parts of the image can become much brighter, so the image can get more “depth.” Colors get expanded to show more bright greens, reds, blues, and everything in between.

Where can you expect to get the best out of HDR?

The main point to note that the higher the dynamic range, the closer it gets to real life. The new generation TVs of today for all the technical brilliance have a limited dynamic range. For this you may miss out on various aspects of the image.

The differences may be visible clearly in live telecasts of outdoor events, especially in the sporting events. You will be able to see the difference when the TV shows images are shown in bright sunlight or in the dark shadows. You cannot specify the certain specific details in the normal televisions.


Advantages of HDR 

However, let’s talk about some benefits of HDR

  • HDR requires a TV that supports it with special HDR content.
  • HDR images are featured with brighter highlights with more contrasts. 
  • Many HDR TVs contain wide color gamut which provides deeper, richer colors with content that supports it.
  • The quality will not same with HDR on a budget HDR TV and HDR on an expensive HDR TV . With the low budget TVs, HDR seems worse than non-HDR.
  • Almost all HDR content today is also available in 4k resolutions. 
  • There are various HDR formats, including “generic” HDR (aka HDR10), Dolby Vision, HDR10+ and more.

Different types of HDR

Today, there are five different types of HDR namely, HDR10, HDR10+, Dolby Vision, HLG and Advanced HDR. The most common form of HDR in use recently is HDR10. Netflix ,Amazon and Blu Ray Disc Association (BDA) have adopted this modern technology for their services to provide viewer’s a great experience. 

Dolby Vision 

Dolby Vision works to support a much wider range of possible settings than the more conventional and static HDR10. Well,  HDR10 supports a maximum picture brightness of 1,000 nits for TVs and on the other hand Dolby Vision supports much brighter — up to 10,000 nits.

How is Dolby Vision different from HDR10?

Dolby Vision is a combination of Dolby Atmos sound and HDR Video. The main difference between Dolby Vision and HDR10 is that the former provides the addition of dynamic metadata on the fly where HDR10 establishes its parameters at the start and sticks to a similar point throughout the film. So, it is assumed that Dolby Vision is more adaptive as compared to HDR10. Moreover, it is able to deliver a superior and amazing viewing experience. It constantly tries to make adjustments so that each image on the screen can be optimized. The devices which currently support Dolby Vision are also able to support HDR10+.  

Frequently Asked Questions
