What Is HDR?

Quick answer: HDR (High Dynamic Range) aims for brighter highlights and wider contrast than SDR, when content is mastered for HDR and the display can use it. An HDR logo is a capability claim, not a promise every stream looks cinematic.

HDR10, HDR10+, Dolby Vision, and HLG differ; brightness and tone mapping vary.

HDR at a glance

• HDR10 is the common baseline; Dolby Vision and HDR10+ can use dynamic metadata.
• Care most for HDR movies or games on a capable set.
• Ignore badges on dim displays if size, Hz, or panel quality matters more.

What HDR means

HDR masters target higher peaks and more highlight detail; the display tone-maps the signal into what its backlight or pixels can produce. A dim LCD can accept HDR and still look washed or dark: format logos do not guarantee impact.

Choose it if / Skip it if

• Choose it for HDR movies, shows, or games in controllable light.
• Compare real brightness, contrast, format support, and panel type.
• Skip obsessing over HDR if you mainly watch SDR or use a dim monitor.
