Dolby Vision or HDR10: Which technology can't miss on a 4K Smart TV?
Anyone looking for a 4K Smart TV should probably have come across some of these terms: Dolby Vision and HDR10. In this article I explain what are the main differences between these technologies and which one you should consider if you are considering buying a TV with the best visual technologies of the moment.
HDR10
HDR stands for High Dynamic Range, present in camera software for mobile phones, smartphone screens and TVs. The purpose of this pattern is the same between these types of devices or platforms: to extend the color gamut, the dynamic range of brightness and contrast. The main advantage of the HDR10 is the ability to brighten areas of shadows and sharpen images and movies.
The HDR10 standard appeared in mid-2015 on some TVs, just as 4K began to appear at major technology fairs in the world. A few years later, Samsung and Amazon spearheaded the development of the second generation HDR10, the HDR10 +, which can better manage brightness intensity, dynamic contrast and color individually.
Basically, Dolby Vision is Dolby's version of the HDR10, with significant improvements. The technology achieves higher brightness levels (10,000 nits versus 5,000 nits of the HDR10 +) and also has the ability to process more colors in different depth fields (only 10 bits versus 12 bits).
Apple TV 4K Announcement with Dolby Vision / Apple Support (disclosure)
Currently in Brazil only LG Ultra HD 4K or 4K TVs have the latest generation of Dolby Vision. Incidentally, LG was the first manufacturer to bring TVs with Dolby's proprietary technology in 2016, which was later expanded to Smart TVs from Sony, Panasonic and Philips. You can find retail TVs with South Korean branded LCD, OLED and NanoCell with this standard, costing between $ 2,000 and $ 7,000.
Dolby Vision or HDR10?
HDR10, as we saw above, is a more popular format capable of processing different types of content, while Dolby Vision requires TV and also titles that are compatible with the format. Yes, if you have a Dolby Vision TV, only formats compatible with this technology will run at top quality.
Netflix is now Dolby's premier partner, making movies, series, documentaries, drawings and other formats compatible with this standard available. However, the user will have to migrate to the Ultra HD plan (R $ 45,90 per month) to have access to the high definition collection with this technology.
On the Adobe website, iTunes appears listed showing compatibility in movies while Amazon Prime Video offers Dolby Vision only on Sony titles:
Dolby Vision / Dolby Compatibility
In the case of HDR10, you only need to have a compatible TV for the technology to be applied in any format. Of course, the HDR10-compatible content will have a more refined and optimized display than one that is just converted and processed into HDR. However, the standard is much broader anyway.
Another point to note is that while the Dolby Vision standard is technically superior, capable of reproducing the content with the highest quality, few TVs are able to fully exploit its potential. The 10,000 nits that the standard achieves may not produce brighter and less blurry images than the HDR10, as on many televisions the maximum brightness is 3,000 nits, especially on the most basic models.
The HDR10 is already great for me.
Finally, I must say that the HDR10 or HDR10 + are more universal standards and better offer content. Many HDR10 TVs will not support Dolby Vision, while those supporting Dolby technology will also feature HDR10 to maximize compatibility. The choice between both is more related to how willing you are to invest in a premium TV than the quality of what will be displayed, as the compatibility between both formats changes a lot.
HDR10 more business
In my case, I recently bought a LG TV that comes with Dolby Vision and HDR, but I confess that the default that I leave the HDR selected, because only then I can see open channels or YouTube videos "converted" in this technology, with a little more brightness, color and sharpness. Dolby appears automatically when the format I choose is compatible, and this only happens inside Netflix in most cases.
And you already knew these technologies? Which format catches your eye most?
