According to news from this site on May 8, the Video Electronics Standards Association (VESA) issued a press release today announcing the DisplayHDR 1.2 specification and stated that there are currently more than 3,000 display models in the world that have passed the DisplayHDR standard certification.
DisplayHDR version 1.2 specification brings more stringent performance requirements. In addition to brightness, color gamut and bit depth, it also introduces color accuracy, contrast, black level ( Black level refers to a number of new test requirements for video signal level (video signal level without a line of light output) and subtitle flicker on a certain calibrated display device.
DisplayHDR v1.2 improves the white brightness level test, changing the 10% center block test on a black background to an 8% center block test on a non-black background.
This change provides testing when the entire screen is lit under more realistic conditions; for example, playing an HDR video in one window versus a typical SDR-style screen The content is displayed on the rest of the screen.
VESA has also tightened requirements for brightness and white point accuracy testing and expanded brightness testing to include a wider test range, from 1 cd/m 2 to nearly 100% logo grade levels.

VESA is trying to solve a big problem with its updated DisplayHDR 1.2 specification: low-end HDR in PC monitors can be really bad.
Roland Wooster, chief engineer at Intel and chairman of the VESA Display Performance Index Group, said that version 1.2 of the specification tightens the relevant restrictions while expanding the scope and standards of testing.
The impact of the new specifications on users’ purchase of monitors will still have to wait for some time. VESA stated that in view of the situation where related products are still being developed, DisplayHDR 1.1 specifications and certifications will be retained until 2025, and notebook computers will be retained until 2026. .
