VESA Introduces AdaptiveSync Display Certification for Gaming Monitors

The Video Electronics Standards Association is introducing a certification program for variable refresh rate monitors. Monitors that meet certain values can receive an AdaptiveSync Display certificate.

There will be several AdativeSync Display logos, which indicate the maximum refresh rate of the screen. Monitors with a refresh rate of at least 144Hz are eligible for certification. The VESA also issues logos for screens with higher refresh rates, such as 165, 240 and 360Hz.

The logo only shows this maximum refresh rate, but screens have to meet more requirements to get a certificate. The requirements for this are laid down in the VESA Adaptive-Sync Display Compliance Test Specification, which, according to the standards organization, has been worked on for two years with dozens of partners. Among others, AMD, Apple, ASUS, Intel, LG, Microsoft, Nvidia and Samsung were involved.

Adaptive-Sync from 60Hz and response time up to 5ms

According to the criteria, Adaptive-Sync must work from a refresh rate of 60Hz or lower. In addition, the gray-to-gray response time over an average of twenty tests should not exceed 5ms at the default overdrive setting. The overshoot and undershoot may not exceed 20 and 15 percent at that setting. There are also requirements for flicker and jitter that the monitors must meet. All requirements and the test method to be used, are contained in a 71 page PDF.

Adaptive-Sync has been part of the DisplayPort standard since 2014. Many monitors have since supported variable refresh rates. Nvidia and AMD have had standards and associated logos for years with which their implementations of the technology are judged in monitors. This concerns the Nvidia G-Sync Compatible and AMD FreeSync Premium certificates. The VESA presents the AdaptiveSync Display certification as an alternative open standard for measuring the performance of variable refresh rate monitors.

Certified monitors

There is already a number of monitors tested and approved for an AdaptiveSync Display certificate. This includes the Dell AW2523HF, which has not yet been announced. That may be a new variant of the Alienware 25 Gaming Monitor, or the AW2521HF. The screen has a 240Hz panel and a full HD resolution. There are also several LG UltraGear monitors on the list, such as the 27GP850, 27GP950 and 32GQ850.

It is expected that the list will be expanded in the near future and that monitor manufacturers will mention the AdativeSync Display certification when announcing new models. Five years ago, VESA introduced the DisplayHDR standard to indicate the HDR capabilities of monitors. The associated logos have been frequently found on monitors since then.

VESA MediaSync Display

The VESA is also introducing a certificate for displays that can play media without jitter, in all common international broadcast formats. Screens with a refresh rate from 60Hz are eligible for this if they support Adaptive-Sync from a value of 48Hz. There are no response time requirements. Both new standards can be assigned to individual monitors as well as laptop screens.
