HDR (High Dynamic Range) technology is something common today in our televisions, with three standards that fight to be the first such as HDR10, HDR10 + and Dolby Vision , of which we are going to tell you their differences below.
But the first thing we have to know is what exactly HDR is . Well, HDR is a technology that allows you to have dark and light areas with much more clarity than without it, so that in the images the blacks are purer and the whites more luminous, with the consequent gain in image quality.
Types of HDR
There are currently three HDR standards on the market which are:
- HDR10 : Being a free and open standard, manufacturers do not have to pay for it and it is widely used.
- HDR10 + : It is an update, rather than an evolution, of the HDR10 created by the collaboration of Samsung and Amazon.
- Dolby Vision : It is a standard owned by Dolby with a quality well above HDR10, and also above HDR10 +.

HDR10 vs HDR10 +
The main difference between HDR10 and HDR10 + is that in the case of HDR10 the metadata is static while in HDR10 + it is dynamic .
The metadata is the data that allows the television to choose the format and way of representing the scenes. For example, metadata is what tells the television how much lighting is required for a type of scene in a movie.
Well, HDR10 being static, it reads the metadata at the beginning of a movie and uses it to configure all the scenes in the same way. For example, if the metadata indicates a specific brightness type, but a scene in the movie falls below that brightness, the scene will be too dark as the TV is limited to accommodate.
With HDR10 +, on the other hand, it incorporates dynamic metadata that allows you to adjust the settings frame by frame (frame by frame) , which they have called Dynamic Tone Mapping .
What is the difference between OLED, Super UHD and Quantum Dots?
Dynamic Tone Mapping allows HDR10 + to adapt to each scene independently for higher image quality and brightness.
The HDR10 + is compatible with all televisions that have HDR10, yes, after a firmware update of the equipment.
HDR10 + vs Dolby Vision
Both HDR10 + and Dolby Vision are standards that use dynamic metadata to provide better adaptability to scenes.
But while HDR10 + works at 10 bits , the Dolby Vision system is at 12 bits .
This is important because the human visual system is especially sensitive to wide images with a uniform brightness (for example, a blue sky) and there the quality provided by the 12 bits of the Dolby Vision system compared to the 10 of the HDR10 +, it does more than patent .
Another difference is found in the color treatment that Dolby Vision does with much more vividness than HDR10 +, something that is not always the most realistic, but it is more spectacular and beautiful, not in vain we are talking about an astonishing number of 68,000 million colors .

In the maximum brightness the differences are also substantial since the HDR10 + can obtain peaks of up to 4,000 nits while the Dolby Vision can go up to 10,000 nits .
The main weakness of Dolby Vision compared to HDR10 + is the fact that it is a proprietary technology of Dolby and not free as with HDR10 +.
Manufacturers that want to have Dolby Vision on their televisions must pay the relevant license fees to the San Francisco company and incorporate a specific chip for this type of processing, which increases the final price of the television and makes its implementation something more slower and lower than HDR10 +.
Once you know the differences between HDR10, HDR10 + and Dolby Vision , you can have more arguments when buying your next television, so it will be much easier for you to decide.
