Yes, you need an AV receiver that supports Dolby Vision to enjoy a home theater experience with your Dolby Vision-enabled TV. This is because Dolby Vision is a high dynamic range (HDR) 4K video format that requires specific hardware and software capabilities to function properly.
While some TVs have built-in Dolby Vision support, an AV receiver that supports Dolby Vision is necessary to fully utilize the format's features. This is because the AV receiver plays a crucial role in processing and decoding the Dolby Vision signal, allowing for the best possible image and sound quality.
Without an AV receiver that supports Dolby Vision, you may not be able to access the full range of features that Dolby Vision offers, such as improved brightness, color accuracy, and contrast. Additionally, an AV receiver that supports Dolby Vision can also provide a more immersive audio experience, such as Dolby Atmos, which is often paired with Dolby Vision content.
In summary, to enjoy a complete home theater experience with your Dolby Vision-enabled TV, it is necessary to have an AV receiver that supports Dolby Vision.
