These days we are seeing TVs having Dolby Vision enabled. Is that a different type of screen that can display better? Read on...

Dolby Vision

Dolby Vision is another attempt by Dolby Labs to bring all the efforts of the color grading team and the directors view to the audience right at home. And to answer the question about how different is Dolby Vision from HDR10, Dolby is a HDR (High Dynamic Range) while HDR10 is static. Meaning, HDR10 stores all the metadata of the video at a single point for the whole video or movie and is determined only once, while Dolby Vision, by adjusting scene by scene or even frame by frame, lets you to see more detail with color accuracy. It renders on the go making adjustments scene by scene. So as of today, we can comfortably say Dolby Vision is an experience.

To give you a comparison, HDR10 supports a maximum picture brightness of 1000 nits while Dolby Vision supports 10000 nits. When it comes to color depth, HDR10 lets the content creators to define colors using 10 bits of data while Dolby Vision supports 12 bit data - You know what this means? No?
10 bit data lets u pick from among 1024 shades from each primary color. Yes. 1024 shades. That is around a billion colors already. Crazy? Wait a moment. Dolby Vision, like I said earlier, supports 12 bit data. This means, it will let you pick from among 4096 shades from each primary color. A total of a lil more than 68 billion colors.
But hang on. The brightest TVs available in the market today are capable of displaying around 3000 nits. However, the advancement in TV technology is rapid. We currently have Dolby Vision enabled TVs. We might sometime have a TV that can truly utilize the capabilities of Dolby Vision  completely.

Advanced version of Dolby Vision is Dolby Vision IQ. This is a feature where Dolby Vision utilizes the sensor on your 4K TV to understand the lighting environment around the TV and adjusts itself to give you the best viewing experience.

2 rupees free knowledge:
The color depth of a TV or monitor is measured in bits. One bit per pixel means that the monitor can display 2 colors. i.e. black or white. A 24 bit per pixel TV or monitor can display 16 million colors. In 8-bit color, 8 bits are used to describe each pixel.
A nit is a measurement of how much light a TV sends to your eyes with in a given area. One nit is the amount of light output equal to one candela per square meter.
