HDR (High Dynamic Range) is a technology that provides a wider dynamic range in an image compared to standard formats (SDR). It allows for brighter highlights, deeper shadows, and more vibrant colors, making the picture incredibly realistic and detailed.
How does HDR work?
Enhanced Brightness: HDR content can utilize peak brightness levels of up to 1000–4000 nits (compared to ~100–300 nits for SDR).
Wider Color Gamut: It supports 10-bit color (over 1 billion shades) versus 8-bit color (16.7 million shades) in SDR.
Local Dimming: The screen’s backlight adapts to the scene, enhancing the contrast between light and dark areas.
Popular HDR Formats
HDR10 — The common, open standard.
Dolby Vision — An advanced format with dynamic metadata for scene-by-scene optimization.
HLG (Hybrid Log-Gamma) — Often used in television broadcasting.
HDR10+ — A dynamic metadata standard developed by Samsung.
What to do if HDR isn’t working?
Make sure your display supports HDR10, Dolby Vision, or HLG.
Check the settings in Windows/macOS/your TV (HDR must be enabled).
Use an HDMI 2.0a (or later) or DisplayPort 1.4 (or later) cable for signal transmission.
