HDR10 vs HDR400 vs HDR600 vs HDR1000: Choosing the Right HDR Standard

High Dynamic Range (HDR) technology fundamentally enhances how images look by expanding brightness, contrast, and color beyond what Standard Dynamic Range (SDR) can deliver.

However, the term “HDR” gets used in different ways: one is HDR10, a content format used in movies and streaming, and another is DisplayHDR, a hardware certification (e.g., HDR400, HDR600, HDR1000) that measures how capable a display is at showing HDR content.

These aren’t interchangeable, one describes content, the other describes display performance.

Understanding the difference between HDR10 vs HDR400/HDR600/HDR1000

HDR10 serves as the foundational standard for HDR content and display capabilities. Established in 2015 by the Consumer Electronics Association (CEA), it defines the basic technical specifications for a display to be considered as having HDR capabilities.

HDR400, HDR600, and HDR1000, on the other hand, are part of the DisplayHDR specification created by the Video Electronics Standards Association (VESA) in 2017, defining the quality of HDR for computer monitors and laptops.

These standards are primarily distinguished by their color capabilities and peak brightness levels which are measured in nits. As the names suggest, HDR400, HDR600, and HDR1000 can reach peak brightness levels of 400, 600, and 1000 nits, respectively.

While this article deals with the DisplayHDR specification, which is geared for LCD displays, there is also a VESA specification designed specifically for emissive display technologies like OLED or Micro LED displays: DisplayHDR True Black.

HDR10 – Content Format

HDR10 is the most widely used HDR content format found in 4K Blu-rays, streaming, and gaming. It tells a display how the content was mastered so it can map brightness and color correctly.

Key points:

Uses 10-bit color depth to show more colors and smoother gradients.
Supports the wide Rec.2020 color space (much broader than Rec.709 used by SDR).
Applies static metadata, meaning brightness/color data stays constant for the whole video.
Content can be mastered for brightness up to ~1000–4000 nits (the standard allows even higher, but most media is in that range).
HDR10 doesn’t guarantee how well a display can show HDR – it only defines the format of the signal/content.
Compared to more advanced HDR standards like HDR10+, Dolby Vision or Hybrid Log Gamma, HDR10’s maximum peak brightness might not showcase the full potential of HDR visuals on displays capable of higher nit levels.

👉 Bottom line: HDR10 tells the display what HDR content is, not how well the display performs. So HDR10 on a poor screen won’t look good unless the display has the hardware to back it up.

HDR10 vs HDR400: HDR10 is an HDR content standard, while HDR400 is a display certification for monitors, so they measure different aspects of HDR and are not directly comparable.

HDR400 – The Entry-Level HDR

HDR400 is the baseline tier in the VESA DisplayHDR certification, designed to ensure that even the most affordable displays deliver a measurable improvement over SDR, though it’s the least ambitious HDR level.

Brightness:

Minimum peak brightness of ~400 nits on an small patch – a noticeable jump from typical SDR displays.
Full-screen sustained brightness of around 320 nits, which prevents dimming when most of the screen is bright.
These brightness thresholds help make highlights in HDR content more visible than on standard monitors.

Contrast & Black Levels:

Requires a static contrast ratio of at least ~1,300:1, which improves perceived depth compared with many SDR panels.
Black levels around 0.4 nits, meaning blacks won’t be truly deep but will be darker than on some SDR screens.
However, local dimming isn’t required at this tier, so real HDR contrast effects are limited.

Color Performance:

Must cover 99 % of the BT.709 (Rec.709) color space, ensuring faithful SDR and basic HDR colors.
Also extended to cover ~90 % of the larger DCI-P3 gamut under the latest spec – which helps with richer HDR colors than older DisplayHDR400 requirements.
Supports 10-bit input with at least 8-bit + 2-bit (FRC) processing for smoother gradients.

👉 Summary: HDR400 gives a modest brightness bump over SDR and meets basic color requirements, but its HDR effect can be limited because peak brightness, contrast, and dimming are minimal compared with higher tiers.

HDR600 – The Middle Ground

HDR600 sits in the mid-range of the DisplayHDR certification lineup, offering a noticeable step up in brightness, contrast, and color performance compared with HDR400 while still being broadly affordable.

Brightness:

Peak luminance of around 600 nits on small highlights.
Sustained brightness around 350 nits for full-screen content.
These levels help highlights in HDR content stand out more than on entry-level displays.

Contrast & Black Levels:

Requires a higher static contrast ratio than HDR400 (~8,000:1 with 1D backlights).
Black levels around 0.1 nits, deeper than lower tiers and enabling more visible shadow detail.
This makes HDR content look more dynamic with better separation between bright and dark areas.

Color Performance:

Maintains 99 % Rec.709 coverage.
Typically ~95 % DCI-P3 or wider, meaning richer colors for HDR content.
Supports 10-bit input with at least 8 bit + 2 bit (FRC) processing, helping smoother color gradients and reducing banding.

👉 Summary: HDR600 is a solid middle path for those who want visible HDR improvements: brighter highlights, better contrast, and wider color gamut, without jumping to the top-end premium tier. The higher contrast requirements at this level typically imply local dimming, which gives greater contrast to the image as different parts of the screen can be dimmed at different rates.

HDR1000 – The Premium Experience

HDR1000 represents the high-end tier in the VESA DisplayHDR certification lineup, designed for displays that deliver striking brightness, deep contrast, and vivid color to make HDR content truly impressive.

Brightness:

Peak luminance of ~1000 nits on small patches — bright highlights really stand out.
Sustained brightness of ~600 nits for full-screen content, so HDR scenes stay punchy even with a lot of bright detail.
These levels ensure brighter highlights and specular details that are closer to what HDR content creators intended.

Contrast & Black Levels:

Very deep black levels (~0.05 nits) with advanced backlighting.
Requires high contrast ratios (often achieved with 2D full-array local dimming), enabling both bright highlights and deep shadows to coexist with minimal wash-out.
This results in rich shadow detail and dramatically better contrast compared with lower tiers.

Color Performance:

Maintains 99 % Rec.709 coverage and ~95 % DCI-P3 or wider for saturated HDR color.
Supports 10-bit video input with at least 8-bit + 2-bit dithering (FRC) processing, helping deliver smoother color gradients and reduce banding in HDR images.

👉 Summary: HDR1000 is ideal for anyone who wants a true premium HDR experience – bright highlights, deep shadows, and wide, smooth color that pulls HDR content to life. It’s typically found in premium monitors and TVs where superior backlighting and color performance are priorities.

Choosing the Right HDR Standard

Here’s a simple way to think about it:

Tier	Brightness	Contrast	Color	HDR Impact
HDR10 (format)	Up to ~1000+ nits content	Static metadata	Wide gamut	Dependent on display
HDR400	~400 nits	Modest	Basic	Slight HDR effect
HDR600	~600 nits	Better contrast	Wider gamut	Noticeable HDR
HDR1000	~1000 nits	High contrast	Wide gamut	Strong HDR experience

HDR10 alone doesn’t guarantee great picture quality – you still need a capable display to realize its potential.
HDR400 is best for casual use or budget devices.
HDR600 is a good balance for gaming and movies.
HDR1000 is ideal if you want a rich HDR experience with impactful highlights and deep blacks.

Q&A

Is HDR400 even worth using?

It’s a modest upgrade at best. HDR400 skips key features like local dimming and wide color gamut, so it won’t deliver true HDR impact – but it can still offer slightly better brightness than standard SDR.

Is HDR 400 HDR10?

No. HDR400 is a brightness certification from VESA, while HDR10 is a content standard. A monitor can process HDR10 signals while only meeting the HDR400 tier, so it accepts the content without displaying it at full quality.

Is HDR400 real HDR?

Only technically. It meets the minimum brightness requirement to carry the HDR label, but without local dimming or a wide color gamut, it lacks the contrast and vibrancy that make HDR worthwhile.

Is HDR10 the best HDR?

No, it’s the entry-level format. HDR10+ and Dolby Vision use dynamic metadata for scene-by-scene adjustments, giving better results than HDR10’s static approach, though HDR10 remains the most widely supported.

Should I use HDR400 for gaming?

Not necessarily. Without local dimming, HDR400 can produce washed-out blacks, so many gamers get better results sticking with a well-calibrated SDR mode.
