VESA Announces Fully Open HDR Standard for Displays

When purchasing a new display today, there are a variety of specifications to consider, such as resolution, refresh rate, and more recently if it supports high dynamic range (HDR). While HDR displays have been available for some time now, there has been no actual agreement within the display industry for what counts as HDR, which can cover increased color gamuts, brightness, and supported bit-depth. To adres the confusion, VESA has announced DisplayHDR, a fully open standard with three levels of HDR support for testing the quality of current and upcoming displays.

The three levels within DisplayHDR are DisplayHDR 400, DisplayHDR 600, and DisplayHDR 1000. DisplayHDR 400 is the lowest, requiring luminance can reach 400 nits, which is as much as 50% more than standard dynamic range (SDR) displays, limits on the amount of light that can escape when the screen is black, and a minimum color gamut of 95% of ITU-R BT.709. DisplayHDR 600 bumps the peak brightness up to 600 nits, has even tighter limits of how much light can leak out, requires a minimum color gamut of 99% BT.709 and 90% DCI-P3 65, and actual support for 10-bit image processing and 8-bit pixel drivers. Most SDR panels do not use 8-bit color signals but 6-bit with dithering used to simulate 8-bit video. DisplayHDR 1000 has much the same requirements as DisplayHDR 600, but with a peak brightness requirement of 1000 nits and still tighter black level performance.

According to the VESA press release, we can expect to see DisplayHDR compliant products at CES next month. There are over two dozen active member companies that contributed to developing these standards, including AMD, Intel, NVIDIA, Asus, Dell, HP, Lenovo, Microsoft, LG, and Samsung.
