VESA is the first standards body to publicly develop a test tool for HDR qualification, utilizing a methodology for performance tests that end users can apply without having to invest in costly lab hardware.
The test tool for DisplayHDR CTS 1.2 is now available for download.
Test tools and measurement templates for all DisplayHDR CTS versions are available for download from the VESA GitHub page.
CTS documents for the DisplayHDR standard are available to the public from VESA.org. (Registration required)
