HARMAN Achieves World-First HDR10+ Automotive Certification

It’s a notable moment for the category, with in-cabin screens steadily moving away from basic information panels and towards something far closer to the home AV experience. StereoNET saw hints of this evolution during our visit to Huawei’s Sound Lab, where the Maestro S800’s sweeping display array showed just how central visual design is becoming to the modern cabin.

The HDR10+ Automotive certification, introduced by HDR10+ Technologies LLC, sets a formal benchmark for how HDR content should behave inside a vehicle — a far more challenging environment than the stable lighting of a lounge room. Rapid swings between bright sun, tunnel darkness and street-level reflections tend to wash out lesser displays. HARMAN worked with Samsung and Panasonic in shaping the specification, which focuses on maintaining consistent brightness, colour accuracy and contrast under these unpredictable conditions.

To qualify, a display must clear a series of tests aimed at ensuring it delivers broadly “cinematic” performance irrespective of where, or when, the car is being driven. HDR10+ Adaptive capability is also required, allowing the system to alter its output in real time as ambient light changes. In theory, this should help navigation, streamed content and driver-assist interfaces retain their depth and clarity rather than collapsing into glare or murkiness. That’s the promise, at least.

Shilpa Dely, HARMAN’s Vice President and Ready Display Business Lead, says the goal has long been to lift the in-car experience to something approaching that of a domestic display. She describes it as a marker manufacturers can trust when assessing in-cabin display quality: 

Earning the world’s first HDR10+ Automotive certification is how we’re delivering on that commitment.

Ready Display itself is based on Samsung’s Neo QLED technology and will be offered in three series — NQ3, NQ5 and NQ7 — each intended to handle the shifting luminance of a car interior. Real-time image processing is used to manage contrast, brightness and colour, with the aim of keeping key information legible without washing out finer detail.

For automotive manufacturers, the certification provides a relatively straightforward point of differentiation. For drivers and passengers, the advantages should be more tangible: clearer routing information, less fatiguing infotainment, and generally more stable picture quality during charging stops or long journeys. HARMAN also suggests the benefits reach beyond entertainment, potentially supporting more intuitive interfaces and improved visibility for safety-critical functions.

Looking ahead, the company points to future use cases such as adaptive instrument clusters and more sophisticated rear-seat entertainment systems designed for families — areas where consistent image handling may become a baseline expectation rather than a premium extra. As vehicles continue their shift toward software-defined platforms, display performance is becoming quietly fundamental to how the whole cabin feels and functions.
