Earlier today, we published an article explaining how HDR, High Dynamic Range, can enhance a 4K TV picture. After it was posted, we have received a few inquiries asking about Dolby Vision and its relationship to 4K and HDR. So we asked our favorite Artificial Intelligence engine, ChatGPT, for its explanation. Here is the AI response. And, as always, the ChatGPT was fact-checked and edited by the TV Answer Man team. Enjoy.
Dolby Vision is a proprietary technology developed by Dolby Laboratories that enhances the visual quality of movies, TV shows, and other forms of content. It is an HDR (High Dynamic Range) technology that provides a wider color gamut, greater brightness, and higher contrast than traditional SDR (Standard Dynamic Range) content. In this article, we’ll explore what Dolby Vision is and how it works.
Dolby Vision is a technology that is designed to work with content that has been mastered using the Dolby Vision system. The process of mastering involves creating a version of the content that is optimized for display on a Dolby Vision-compatible display device. This involves creating a version of the content that contains metadata that describes how the content should be displayed. This metadata includes information about the content’s color space, brightness levels, and contrast ratios.
When this content is played back on a Dolby Vision-compatible display device, the display device reads the metadata and adjusts its settings to display the content as accurately as possible. This means that the display device will adjust its color space, brightness levels, and contrast ratios to match the metadata in the content. This results in a more accurate representation of the original content, with more vibrant colors, greater contrast, and brighter highlights.
One of the key features of Dolby Vision is its ability to provide dynamic metadata. This means that the metadata is not fixed for the entire duration of the content, but rather can change from frame to frame. This allows for a more precise adjustment of the display device’s settings, resulting in a more accurate representation of the content.

Another key feature of Dolby Vision is its support for a wide color gamut. This means that content mastered using Dolby Vision can contain a much wider range of colors than traditional SDR content. This allows for more accurate and vibrant colors that are closer to what the human eye can see.
Dolby Vision also supports high brightness levels, which means that content can have brighter highlights than traditional SDR content. This allows for more dynamic and visually stunning content, especially in scenes that contain bright objects or sunlight.
In order to enjoy Dolby Vision content, you need a display device that is Dolby Vision-compatible. This means that the display device can read the metadata contained in the content and adjust its settings accordingly. Many modern TVs, Blu-ray players, and streaming devices support Dolby Vision, so it is becoming increasingly common in the market.
In conclusion, Dolby Vision is a technology that enhances the visual quality of content by providing a wider color gamut, greater brightness, and higher contrast than traditional SDR content. It works by using metadata to adjust the display device’s settings to accurately represent the content. Dolby Vision is becoming increasingly common in the market, so it’s worth considering a Dolby Vision-compatible display device if you want to enjoy the best possible visual experience.

Fantastic! Hurray for AI.. Sarah Connor?
i am very confused. i checked the website RTINGS.com and they reviewed a TV model called the HISENSE A6H that is reported to over both HDR10 and DOLBYVISION but this website says that this TV does not have wide color gamut.how could a TV offer DOLBYVISION and at the same time not have wide color gamut?
i meant to say “that website” and not “this website” as you can see i have terrible grammer.
