Standards
What is the maximum peak brightness specification that Dolby Vision supports?
Correct! Dolby Vision is specified to support peak brightness up to 10,000 nits, far beyond what current consumer displays can achieve. This headroom future-proofs the format as display technology continues to advance.
Not quite. Dolby Vision's specification tops out at 10,000 nits, which is a deliberately ambitious ceiling. While no consumer TV today reaches that figure, the spec ensures the format won't become outdated as display brightness improves.

HDR
What type of metadata does Dolby Vision use that sets it apart from standard HDR10?
Correct! Dolby Vision uses dynamic metadata, which can adjust HDR parameters on a scene-by-scene or even frame-by-frame basis. This allows the display to optimise brightness, contrast, and colour far more precisely than HDR10's static approach.
Not quite. The key differentiator for Dolby Vision is its use of dynamic metadata. Unlike HDR10, which applies a single set of values to an entire film, dynamic metadata lets Dolby Vision fine-tune the image moment by moment for a more consistent and accurate picture.

History
In approximately what year did Dolby Laboratories first introduce Dolby Vision as a commercial HDR format?
Correct! Dolby Vision was commercially launched in 2014, initially rolled out in cinemas before making its way into consumer televisions and streaming services. It was one of the earliest premium HDR formats to reach the market.
Not quite. Dolby Vision debuted commercially in 2014, giving it a strong head start in the HDR race. It began in professional cinema environments before Dolby pushed it into the living room through TV partnerships and streaming platforms.

Bit Depth
What is the maximum colour bit depth that Dolby Vision supports per channel?
Correct! Dolby Vision supports up to 12-bit colour depth per channel, enabling billions of possible colour values. This significantly reduces banding and allows for smoother gradients compared to the 10-bit limit of standard HDR10.
Not quite. Dolby Vision goes up to 12-bit colour per channel, which is a meaningful step beyond HDR10's 10-bit ceiling. More bits means more gradations between colours, resulting in smoother skies, skin tones, and shadow detail in compatible content.
05 / 8
Streaming
Which streaming platform was among the first to offer Dolby Vision content to consumers?
Correct! Netflix was a pioneering streaming partner for Dolby Vision, helping bring the format to living rooms worldwide from the mid-2010s. The platform invested heavily in producing and delivering Dolby Vision content alongside compatible device support.
Not quite. Netflix was one of the very first streaming services to adopt Dolby Vision, partnering with Dolby in the early days of the format's consumer rollout. This relationship helped establish Dolby Vision as the premium HDR standard for streaming.

Display Tech
What is the minimum black level that Dolby Vision's specification supports?
Correct! Dolby Vision specifies black levels down to 0.0001 nits, which is extraordinarily close to absolute black. This enormous contrast range between the darkest and brightest values is a core reason why Dolby Vision images can look so strikingly lifelike.
Not quite. The answer is 0.0001 nits, which represents an incredibly deep black level in Dolby Vision's specification. Combined with the 10,000-nit peak brightness ceiling, this gives the format a staggering contrast ratio that challenges the limits of current display hardware.
07 / 8
Devices
Which Apple device lineup was among the first to both record and display Dolby Vision video?
Correct! The iPhone 12 lineup, launched in 2020, was a landmark moment as it could both capture and play back Dolby Vision HDR video. This made high-quality HDR filmmaking accessible to everyday users for the first time.
Not quite. It was the iPhone 12 series in 2020 that brought Dolby Vision recording to smartphones. Apple's integration was groundbreaking because users could shoot, edit in apps like iMovie, and share true Dolby Vision footage directly from their pocket.
08 / 8
Formats
What is the name of the royalty-free HDR format that is most commonly considered Dolby Vision's main open-standard competitor?
Correct! HDR10+ is the most direct competitor to Dolby Vision, developed by Samsung and Amazon as a royalty-free alternative that also uses dynamic metadata. It aims to deliver a similar scene-by-scene optimisation without the licensing fees associated with Dolby Vision.
Not quite. While HDR10 and HLG are widely used formats, HDR10+ is the closest rival to Dolby Vision because it also uses dynamic metadata. Backed by Samsung and Amazon, HDR10+ was created specifically to offer a fee-free alternative with comparable picture intelligence to Dolby Vision.
