HDR (High Dynamic Range) used to be a feature specific to cameras, but recently HDR got into phones and televisions with solutions like HLG, HDR10 or Dolby Vision. The Video Electronics Standards Association (VESA) has now announced DisplayHDR open standard specifying high dynamic range (HDR) quality for PC monitors and laptop displays that use liquid crystal display (LCD) panels.
DisplayHDR version 1.0 specifies three levels of HDR system performance (DisplayHDR 400, 600 and 1,000) with different white luminance, black level, and bit-depth “performance”. An automated testing tool will be available for the users to perform their own testing if required.
HDR display in PC will mostly be useful while watching movies, gaming, and creating photo and/or video content. The requirements for DisplayHDR 400, DisplayHDR 600, and DisplayHDR 1000 are listed in details in the table below from DisplayHDR.org website.
Eventually DisplayHDR will also support the less common OLED display, and a list of certified products will be posted on the website. The DisplayHDR test tool will be available in Q1 2018, but you can already download the DisplayHDR CTS (Compliance Test Specification) v1.0 for the full details.
