HDR vs SDR: What is the Difference in Video and Display?
Published on April 12, 2026
HDR (High Dynamic Range) shows a wider range of brightness and color than SDR (Standard Dynamic Range). HDR content can display bright highlights above 1,000 nits and deep blacks simultaneously, while SDR is capped around 100-300 nits. The result is more realistic images with visible detail in both shadows and bright areas.
Brightness and Contrast
SDR content uses a limited brightness range, typically peaking at 100 nits. HDR content can reach 1,000 to 4,000 nits on capable displays. This extra range means a sunset scene in HDR shows glowing orange highlights alongside visible shadow detail in the foreground, while SDR would either clip the highlights or crush the shadows. The expanded contrast ratio is the single biggest visual improvement HDR brings.
Color Range
SDR uses the Rec. 709 color space, which covers about 35% of all visible colors. HDR uses Rec. 2020 (or DCI-P3 in practice), covering roughly 75% of visible colors. This means HDR can show more saturated reds, greens, and blues that SDR literally cannot produce. You notice this most in nature footage, neon-lit scenes, and vivid animations.
Color Depth
SDR uses 8-bit color, which encodes 16.7 million colors. HDR uses 10-bit or 12-bit, encoding over 1 billion colors. The extra bit depth eliminates banding, those visible step patterns you sometimes see in gradients like blue skies or dark shadows in SDR content.
HDR Formats
HDR10 is the most common standard and is free to use. HDR10+ (Samsung) and Dolby Vision (Dolby) add dynamic metadata that adjusts brightness per scene or per frame. Most 4K TVs sold today support at least HDR10. Dolby Vision typically looks best but requires licensing.
File Size and Requirements
HDR video files are 20-50% larger than SDR at the same resolution because of higher bit depth and wider color data. Streaming HDR requires about 25 Mbps for 4K HDR on Netflix. You also need an HDR-capable display to see any benefit. Playing HDR content on an SDR screen gives you a washed-out image unless the player tone-maps it down properly.
