What is the difference between HDR10+ and Dolby Vision
HDR (High Dynamic Range) is a technology that allows displays to produce a wider range of colors and brightness levels, resulting in a more realistic and immersive viewing experience. There are several HDR formats available, but two of the most popular ones are HDR10+ and Dolby Vision.
HDR10+
HDR10+ is an open standard created by Samsung and adopted by several other companies. It uses dynamic metadata, which means that the brightness and color information for each scene is adjusted in real time, resulting in more accurate and vivid images. Unlike HDR10, which has static metadata that is the same for the entire video, HDR10+ allows for scene-by-scene adjustments, which can result in more consistent and dynamic viewing experience.
Dolby Vision
On the other hand, Dolby Vision is a proprietary format developed by Dolby Laboratories. It also uses dynamic metadata, but it can adjust the brightness and color information on a frame-by-frame basis, resulting in even more precise and nuanced images. It also supports a wider color gamut and can produce brighter highlights and deeper blacks than HDR10+.

System Requirements
The system requirements for color grading in HDR10+ and Dolby Vision can vary depending on the specific software and hardware being used. Generally, the process requires a high-performance computer with a powerful processor, a dedicated graphics card with support for HDR content, and a display that is capable of displaying HDR content accurately. Additionally, the software being used for color grading should have the necessary tools and capabilities for HDR content, such as support for high bit depth and wide color gamut. It’s important to check the system requirements of the specific software and hardware being used to ensure that they meet the recommended specifications for HDR color grading.
To take full advantage of HDR10+ and Dolby Vision, monitors should meet certain requirements. These include:
- High Dynamic Range (HDR) Support: The monitor should support HDR10+ or Dolby Vision. This means that it should be able to display a wider range of colors and a higher level of brightness.
- Wide Color Gamut (WCG) Support: The monitor should support a wide color gamut, such as DCI-P3 or Rec. 2020. This allows for a greater range of colors to be displayed.
- High Brightness: The monitor should be capable of high brightness levels, typically around 1000 nits or more. This is necessary to achieve the full effect of HDR.
- Local Dimming: The monitor should have local dimming technology, which allows for different areas of the screen to be dimmed or brightened independently. This helps to achieve higher contrast ratios.
- 10-bit Color Depth: The monitor should support a 10-bit color depth, which allows for a greater number of colors to be displayed and smoother color gradients.
- Calibration: The monitor should be calibrated to ensure accurate color reproduction and brightness levels.
Meeting these requirements will ensure that the monitor is capable of displaying HDR10+ and Dolby Vision content with the full intended effect.

So, which one is better? Well, it depends on your perspective. Dolby Vision certainly has some advantages, especially when it comes to color accuracy and contrast. It also has wider industry support, as many streaming services and content creators have adopted the format. However, it requires a license from Dolby Laboratories, which can add to the cost of products that support it.
HDR10+, on the other hand, is an open standard that is available to anyone who wants to use it. It also has support from several major TV manufacturers, including Samsung, Panasonic, and Philips. While it may not be quite as precise as Dolby Vision, it still offers a significant improvement over traditional SDR (Standard Dynamic Range) displays.
In the end, both HDR10+ and Dolby Vision are great options for improving your viewing experience. Which one you choose may depend on the specific features you’re looking for and the content you want to watch. However, regardless of which format you choose, you can expect to enjoy more vibrant colors, brighter highlights, and deeper blacks than ever before.
