The DisplayHDR™ Test Tool allows users to confirm the display parameters including brightness, color and contrast performance of high dynamic range (HDR) laptop and desktop monitors as per the set forth in VESA’s High-Performance Monitor and Display Compliance Test Specification (DisplayHDR). Created by VESA®, the Video Electronics Standards Association, this new test tool has a simple keyboard interface that enables professional and lab-level users of off-the-shelf calibration colorimeters to test and evaluate HDR displays at the three performance levels (DisplayHDR 400, 600 and 1000) outlined in the DisplayHDR specification.
