> HDR10+ is an open, royalty-free dynamic HDR standard developed and governed by HDR10+ Technologies, LLC — jointly owned by Samsung and Panasonic. It delivers scene-by-scene tone mapping of brightness, contrast, and color using dynamic metadata (SMPTE ST 2094-40), ensuring HDR content is displayed as close as possible to the colorist's creative intent on every certified display. More than 180 companies have adopted the standard and over 22,000 products are certified worldwide.

## The Standard

HDR10+ extends the baseline HDR10 standard (SMPTE ST 2084 / PQ transfer function, BT.2020 color primaries) with dynamic metadata that adjusts the tone mapping curve on a scene-by-scene or frame-by-frame basis. The standard supports a peak brightness range of 0–10,000 nits via the full PQ curve. HDR10+ is fully backward compatible: HDR10+ content plays correctly on HDR10-only displays using the static metadata layer.

HDR10+ metadata is carried as SEI messages in HEVC bitstreams and in AV1 and VP9 streams. The specification is SMPTE ST 2094-40.

## Variants

**HDR10+ ADVANCED** — extends HDR10+ with four additional metadata-driven features for premium display implementations:
- Enhanced Overall Brightness (HDR10+ Bright): raises scene brightness beyond the standard tone mapping floor where display capability allows, without violating Filmmaker Mode
- Intelligent Motion Smoothing: content providers embed scene-by-scene creative latitude for motion processing (scale 0–5), allowing certified displays to reduce judder while respecting the filmmaker's intent. Reference point: 14 foot-lambert cinema experience.
- Local Tone Mapping: defines elliptical, circular, or rectangular regions of the frame for independent tone mapping, enabling simultaneous detail in bright highlights and dark shadows within the same scene
- Content Descriptive Metadata: genre classification (Movie, Sports, Animation, News, General) plus 64-bit scene attribute tags (lighting environment, motion type, camera perspective, content origin, etc.) that certified displays can use to optimize image processing per scene. Tag system is extensible; HDR10+ Technologies, LLC is the registrar for new tags.
Amazon Prime Video became the first streaming service to deliver HDR10+ ADVANCED content in 2026 on Samsung-certified displays.

**HDR10+ GAMING** (also known as Source Side Tone Mapping / SSTM) — enables GPU-side tone mapping for interactive game content. The game engine reads the certified display's declared peak luminance capability via EDID/VSVDB and renders HDR output precisely matched to that display. Signals are carried over HDMI 2.0 or later, or DisplayPort 1.4 or later. Auto Low Latency Mode (ALLM) activates automatically on certified displays. Certified GPU sources include NVIDIA and Intel.

**HDR10+ ADAPTIVE** — extends HDR10+ with real-time ambient light compensation. Certified displays use a built-in sensor to continuously adjust tone mapping based on room br
