Last January CES 2020 was again sprinkled with new terms and standards, including the Filmmaker Mode and Dolby Vision IQ. We will see both standards from 2020 on many televisions. We have already discussed the Filmmaker Mode extensively, so in this article we will focus on Dolby Vision IQ. This standard should improve the HDR display for everyone, but what exactly is it and how does it work?

Dolby Vision IQ: what is it and how does it work?

Let's start right away with one clear fact: Dolby Vision IQ is not a new HDR standard. It is a mode (or function) that takes the well-known Dolby Vision HDR standard to a higher level. So a TV has Dolby Vision support to display the Dolby Vision standard, and possibly also the Dolby Vision IQ mode to lift HDR to a higher level.

Dolby Vision takes care of it intelligent way for the image quality of Dolby Vision content to be optimized in every room or room. This is done by looking at the metadata of a Dolby Vision movie or series and by using the light sensors that are built into the TV, which analyzes the ambient light in the room. The dynamic 'tone mapping' of Dolby Vision is adjusted on the basis of this information so that you see the most details in both high and low ambient light and get the best HDR display.

In addition, Dolby claims that Dolby Vision IQ allows television to better understand which content is being played. Using the metadata of Dolby Vision content and the IQ function, the TV can immediately respond to changing input or channel and adjust the optimum settings accordingly. For each type or genre of content, the situation is reviewed and the TV itself automatically adjusts the settings.

Dolby Vision IQ can be found on various televisions from major manufacturers from the beginning of 2020. Panasonic and LG, among others, have announced televisions with this mode, in addition to naturally supporting Dolby Vision as an HDR standard. Unfortunately it is not possible to give older televisions access to the new IQ mode through an update.
