The High-Performance Monitor and Display Compliance Test Specification (DisplayHDR) from VESA defines the display industry’s first fully open standard specifying HDR quality, including luminance, color gamut, bit depth, and rise time. Microsoft: "The compiler guarantees that no user-overloaded equality operator == is invoked when expression x is null is evaluated. The DisplayPort standard is available to VESA Members only.
