DisplayHDR Specs

High Dynamic Range (HDR) displays deliver better contrast and color accuracy, as well as more vibrant colors, compared to Standard Dynamic Range (SDR) displays. As a result, HDR is gaining interest for a wide range of applications, including movie viewing, gaming, and creation of photo and video content. HDR logos and brands abound, but until now, there has been no open standard with a fully transparent testing methodology. Since HDR performance details are typically not provided, consumers are unable to obtain meaningful performance information.

What is DisplayHDR?

The High-Performance Monitor and Display Compliance Test Specification (DisplayHDR) from VESA defines the display industry’s first fully open standard specifying HDR quality, including luminance, color gamut, bit depth, and rise time (see EE Times article). With DisplayHDR, VESA is helping to alleviate consumer confusion surrounding HDR performance specifications in the PC space by:

  • Creating an open specification for the PC industry shared publicly and transparently
  • Developing an automated testing tool that end users can download to perform their own testing if desired. You can download DisplayHDR Test Tool for HDR display performance verification aimed at professional users here.
  • Delivering a robust set of test metrics for HDR that clearly articulates the performance level of the device being purchased

The first release of the DisplayHDR specification, DisplayHDR version 1.0, was introduced in December 2017 and is geared toward liquid crystal displays (LCDs). In January 2019, VESA followed this up with the release of the DisplayHDR True Black standard, a variant on DisplayHDR, which is optimized for emissive display technologies – including organic light emitting diode (OLED) and future microLED displays. DisplayHDR True Black allows for significantly deeper black levels in addition to greater dynamic range and improved rise time – enabling a visually stunning experience for home theater and gaming enthusiasts in subdued lighting environments.

DisplayHDR Performance Levels

The DisplayHDR specification for LCDs establishes four distinct levels of HDR system performance to facilitate adoption of HDR throughout the PC market: DisplayHDR 400, DisplayHDR 500, DisplayHDR 600, and DisplayHDR 1000. The DisplayHDR True Black specification for OLED and other emissive displays includes two levels of HDR system performance: DisplayHDR True Black 400 and DisplayHDR True Black 500. Additional tiers are expected to be added later for both standards to support continuous innovations and improvements in display performance. All tiers require support of the industry standard HDR10 format.

First genuine entry point for HDR.

Significant step up from SDR baseline:

  • True 8-bit image quality – on par with top 15% of PC displays today
  • Global dimming – improves dynamic contrast ratio
  • Peak luminance of 400 cd/m2 – up to 50% higher than typical SDR
  • Minimum requirements for color gamut and contrast exceed SDR

HDR with local dimming, for thinner, lower-cost, lower-power laptops and monitors.

True local dimming and high-contrast HDR at the lowest price point and thermal impact:

  • Peak luminance of 500 cd/m2 – optimized for better thermal control in super-thin notebook displays
  • Same color gamut, black level and bit-depth requirements associated with DisplayHDR 600 and DisplayHDR 1000 levels
  • Includes local dimming
  • Requires 10-bit image processing

Targets professional/enthusiast-level laptops and high-performance monitors.

True high-contrast HDR with notable specular highlights:

  • Peak luminance of 600 cd/m2 – double that of typical displays
    • Full-screen flash requirement renders realistic effects in gaming and movies
  • Real-time contrast ratios with local dimming – yields impressive highlights and deep blacks
  • Visible increase in color gamut compared to already improved DisplayHDR 400
  • Requires 10-bit image processing

Targets professional/enthusiast/content-creator PC monitors.

Outstanding local-dimming, high-contrast HDR with advanced specular highlights:

  • Peak luminance of 1000 cd/m2 – more than 3x that of typical displays
    • Full-screen flash requirement delivers ultrarealistic effects in gaming and movies
    • Unprecedented long duration, high performance ideal for content creation
  • Local dimming yields 2x contrast increase over DisplayHDR 600
  • Significantly visible increase in color gamut compared to DisplayHDR 400
  • Requires 10-bit image processing

Incredibly accurate shadow detail for a remarkable visual experience.

Deeper black levels and dramatic increases in dynamic range create a remarkable visual experience:

  • Peak luminance of 400 cd/m2
  • Brings permissible black level down to 0.0005 cd/m2 – the lowest level that can be effectively measured with industry-standard colorimeters
  • Provides up to 50X greater dynamic range and 4X improvement in rise time compared to DisplayHDR 1000
