Dolby Vision IQ: Improve the HDR Content of Your TV

Dolby now has some of the most advanced standards in terms of image and sound. In sound we find Dolby Atmos, the most widespread three-dimensional sound technology, and that competes with DTS: X. On the other hand, we have Dolby Vision , the most advanced HDR standard that competes with HDR10 and HDR10 + . Now, the company has presented a great improvement for Dolby Vision with Dolby Vision IQ , in addition to collecting industry members that support Dolby Atmos Music .

Dolby Vision IQ

Dolby Vision is the most advanced and most prepared HDR standard for the future. HDR10 + is now tied for performance (4,000 nits, 10 bits and dynamic metadata), but Dolby wanted to go one step further to improve the viewing experience by using the ambient light sensors of the TV.


To do this, Dolby Vision IQ uses the dynamic metadata of Dolby Vision and the ambient light sensors of the TV to detect the brightness of the environment and thus adapt the content to the room in which we are watching.

Among the settings that are modified on the TV to adapt the content is the brightness of the TV, as well as the color temperature. The first one will be modified depending on whether the sun comes in or if we are at night, where in the latter case it will not take so much maximum brightness. As for the color, at sunset the content may look more orange, so the TV adjusts with a slightly colder color to compensate.

The TV will also change settings depending on the content we are watching. For example, if we are seeing a landscape with snow, and suddenly it goes to a dark one, it will be detected intelligently. So far manufacturers like LG and Panasonic have confirmed that they will use it on their televisions.

With this improvement, Dolby seeks to differentiate itself from HDR10 +, which currently matches performance according to the content currently being mastered with 10 bits and 4000 nits of brightness, although Dolby Vision supports up to 12 bits and 10,000 nits, although there is still time for televisions to support these benefits. Also, together with the Filmmaker Mode , a better experience of viewing HDR content at home is being achieved.

Dolby Atmos Music

Although the standard was announced a few months ago, Dolby recalled at the CES of 2020 what the technology consists of and has shown some of the experiences that we can already enjoy under this standard. Among the music labels that are releasing music under this standard are Universal Music Group and Warner Music Group, with songs by artists such as Ariana Grande, The Beatles, Coldplay, Elton John, J Balvin, Lady Gaga, Marvin Gaye, Post Malone, Shawn Mendez and The Weeknd.

Currently, to be able to listen to the content in Dolby Atmos Music it is necessary to have a subscription to Amazon Music HD and an Echo Studio, or TIDAL on compatible Android phones and tablets. Hopefully in the future it will reach more devices, especially the speakers and amplifiers compatible with this standard.
