VESA has published an update to its Adaptive-Sync Display Compliance Test Specification (Adaptive-Sync Display CTS). It is the first publicly open standard for front-of-screen performance of variable refresh rate displays, according to VESA.
Adaptive-Sync Display version 1.1a provides updated testing procedures and logo support for displays that can operate at different maximum refresh rates when resolution is reduced. This optional “Dual Mode” testing and logo support allows display OEMs with qualifying hardware to certify their products at two different sets of resolution and refresh rates (for example, 4K/144Hz and 1080p/280Hz).
Adaptive-Sync Display v1.1a also includes an update that allows display OEMs to achieve a higher AdaptiveSync Display refresh rate certification for displays that support an “overclocked” or faster mode option that is not enabled by default in the factory configuration. In such cases, the overclocked mode must support Adaptive-Sync-enabled GPUs in a non-proprietary manner, and the display must pass all of the rigorous Adaptive-Sync Display compliance tests in both its factory default mode, and completely retested a second time in the overclocking mode.
Both the dual mode and overclocking changes to the Adaptive-Sync Display CTS v1.1a only apply to the VESA Certified AdaptiveSync Display logo program; they do not apply to the VESA Certified MediaSync Display logo program, maintained VESA.
