HDR peak brightness
The maximum brightness a display can reach on small highlights in HDR content, measured in nits.
Full Definition & Technical Explanation
HDR peak brightness is the highest luminance a display can produce on small, bright highlights — measured in nits — while showing HDR material. Unlike full-screen brightness, peak brightness determines how much punch specular highlights (sun glints, explosions) have.
Higher peak brightness pairs with local dimming to deliver convincing HDR; certification tiers such as DisplayHDR 1000 specify minimum levels.
