In the age of 4K and ultra-high-definition displays, terms like HDR10, HDR400, and HDR10+ are becoming increasingly common. Yet, many people are still unsure about what they mean, how they differ, and which one delivers the best viewing experience.
This article will provide a deep dive into what HDR10 is, explain HDR400, clarify the difference between HDR10 and HDR400, and even look at how HDR10 compares to HDR10+. More importantly, we’ll introduce a powerful AI-driven solution—UniFab HDR変換 AI(UniFab HDR Upconverter AI)—that allows you to convert SDR content into HDR10-quality video for a stunning visual upgrade.
What Is HDR?
Before diving into HDR10 vs HDR400, let’s first understand what HDR actually is.
- HDR (High Dynamic Range) improves video quality by increasing contrast, brightness, and color accuracy.
- Unlike SDR (Standard Dynamic Range), which has limited color depth and brightness, HDR allows for more realistic and lifelike visuals.
- The result: highlights are brighter, shadows reveal more detail, and colors appear more vibrant.
Different HDR formats exist, such as HDR10, HDR400, HDR10+, Dolby Vision, and HLG. Among these, HDR10 and HDR400 are among the most widely discussed.
What Is HDR10?
HDR10 is the most common HDR standard today. Here’s what you need to know:
- Bit Depth: 10-bit color, allowing over 1 billion shades.
- Peak Brightness: At least 1,000 nits.
- Metadata: Uses static metadata (same tone mapping for the entire video).
- Compatibility: Supported by most TVs, monitors, Blu-ray discs, and streaming platforms.
In short, HDR10 delivers a massive upgrade over SDR, making it the default HDR format across the industry.
What Is HDR400?
You may have come across displays labeled DisplayHDR 400, or simply HDR400. So, what does HDR400 mean?
- HDR400 is not a content format like HDR10—it is a certification standard from VESA (Video Electronics Standards Association).
- It requires displays to achieve 400 nits of peak brightness.
- HDR400-certified monitors are often entry-level HDR displays.
- They may support HDR10 input but deliver a less impactful HDR experience compared to higher-tier certifications like HDR600 or HDR1000.
So, HDR400 is basically the minimum standard for HDR displays, offering improvements over SDR but not as dramatic as HDR10 on premium devices.
The Difference Between HDR10 and HDR400
Now that we’ve defined both, let’s compare HDR10 vs HDR400.
👉 Key takeaway: HDR10 is a format for HDR content, while HDR400 is a display performance standard. They are not directly equivalent, but often discussed together because HDR400-certified monitors commonly support HDR10 playback.
The Difference Between HDR10 and HDR10+
Another common question is: How does HDR10 compare to HDR10+?
- HDR10: Uses static metadata, meaning the same tone mapping applies throughout the video.
- HDR10+: Uses dynamic metadata, adjusting brightness and color scene-by-scene or even frame-by-frame.
- Result: HDR10+ delivers more precise contrast and color, especially in scenes with varying brightness.
While HDR10 is the industry baseline, HDR10+ provides a premium experience, rivaling Dolby Vision in quality.
Why HDR Matters for Video
When you watch a video in HDR10 or HDR10+, you immediately notice:
- Greater contrast: Blacks are deeper, whites are brighter.
- Richer colors: More shades and gradients, avoiding banding.
- Enhanced detail: Both in shadows and highlights.
But here’s the problem: Most videos online and even many old movies are still in SDR. That’s where AI-powered HDR conversion tools come in.
