VESA Defines New Standard to Help Speed PC Industry Adoption of High Dynamic Range Technology in Laptop and Desktop Monitor DisplaysSAN JOSE, Calif., Dec. 11, 2017 /PRNewswire/ -- The Video Electronics Standards Association (VESA®) today announced it has defined the display industry's first fully open standard specifying high dynamic range (HDR) quality, including luminance, color gamut, bit depth and rise time, through the release of a test specification. The new VESA High-Performance Monitor and Display Compliance Test Specification (DisplayHDR) initially addresses the needs of laptop displays and PC desktop monitors that use liquid crystal display (LCD) panels. The first release of the specification, DisplayHDR version 1.0, establishes three distinct levels of HDR system performance to facilitate adoption of HDR throughout the PC market. HDR provides better contrast and color accuracy as well as more vibrant colors compared to Standard Dynamic Range (SDR) displays, and is gaining interest for a wide range of applications, including movie viewing, gaming, and creation of photo and video content. VESA developed the DisplayHDR specification with the input of more than two dozen active member companies. These members include major OEMs that make displays, graphic cards, CPUs, panels, display drivers and other components, as well as color calibration providers. A list of participating companies is available at www.displayhdr.org. DisplayHDR v1.0 focuses on LCDs, which represent more than 99 percent of displays in the PC market. VESA anticipates future releases to address organic light emitting diode (OLED) and other display technologies as they become more common, as well as the addition of higher levels of HDR performance. While development of DisplayHDR was driven by the needs of the PC market, it can serve to drive new levels of HDR performance in other markets as well.

What DisplayHDR Includes
"We selected 400 nits as the DisplayHDR specification's entry point for three key reasons," said Roland Wooster, chairman of the VESA task group responsible for DisplayHDR, and the association's representative from Intel Corp. for HDR display technology. "First, 400 nits is 50 percent brighter than typical SDR laptop displays. Second, the bit depth requirement is true 8-bit, whereas the vast majority of SDR panels are only 6-bit with dithering to simulate 8-bit video. Finally, the DisplayHDR 400 spec requires HDR-10 support and global dimming at a minimum. With this tiered specification, ranging from baseline to high-end HDR performance levels, PC makers will finally have consistent, measurable HDR performance parameters. Also, when buying a new PC, consumers will be able to view an HDR rating number that is meaningful and will reflect actual performance." "Developing this specification is a natural expansion of our range of video standards," said Bill Lempesis, VESA executive director. "Moreover, we are the first standards body to develop a publicly available test tool for HDR qualification, utilizing a methodology for the above-mentioned tests that end users can apply without having to invest in costly lab hardware. Most of the tests require only a colorimeter, which many users already own. Ease of testing was a must-have requirement in order to make DisplayHDR a truly viable, consumer-friendly spec." New products complying with the DisplayHDR specification will be demonstrated at the Consumer Electronics Show (CES), January 9-12, 2018 at the Las Vegas Convention Center South Hall, DisplayPort booth #21066.
