The Video Electronics Standard Association (VESA) is making an attempt to create a unified grading system for High Dynamic Range technology. The idea is to provide consumers with a more accurate picture of what they are getting with each HDR display; instead of simply allowing manufacturers to slap the HDR label on every product.
DisplayHDR only covers LCD displays for now, leaving OLED screens out of the grading. It will grade future products according to three different grades of HDR performance.
For example, a DisplayHDR-400 certified monitor will need to playback HDR content on a panel that can at least hit peak brightness of 400 nits. It also needs to support 10bit encoding and 95% of sRGB coverage. With each rating, a higher standard must be adhered to receive the certification from VESA.
A big part for the new standard is the adherence to colour gamut coverage. Both the 600 and 1000 certification call for wide colour coverage to ensure the proper colour spectrum is represented on screen. At the same a high contrast output is also preferred before the certification can be given to the manufacturer.
Ideally, this will give use a better idea of what displays mean when they say HDR enabled. If anything, it’ll give OEMs something new to compete at, and perhaps make for a more informed consumer.
