VESA Launches Industry's First Open Standard and Logo Program for PC Monitor and Laptop Display Variable Refresh Rate Performance for Gaming and Media Playback

VESA Adaptive-Sync Display Compliance Test Specification establishes clear benchmarks for consumers to compare variable refresh rate performance of displays supporting the VESA Adaptive-Sync protocol

The Video Electronics Standards Association (VESA ® ) today announced the first publicly open standard for front-of-screen performance of variable refresh rate displays. The VESA Adaptive-Sync Display Compliance Test Specification (Adaptive-Sync Display CTS) provides for a comprehensive and rigorous set of more than 50 test criteria, an automated testing methodology and performance mandates for PC monitors and laptops supporting VESA's Adaptive-Sync protocols.

The Adaptive-Sync Display CTS also establishes a product compliance logo program comprising two performance tiers: AdaptiveSync Display , which is focused on gaming with significantly higher refresh rates and low latency; and MediaSync Display , which is designed for jitter-free media playback supporting all international broadcast video formats. By establishing the VESA Certified AdaptiveSync Display and MediaSync Display logo programs, VESA will enable consumers to easily identify and compare the variable refresh rate performance of displays supporting Adaptive-Sync prior to purchase. Only displays that pass all Adaptive-Sync Display CTS and VESA DisplayPort™ compliance tests can qualify for the VESA Certified AdaptiveSync Display or MediaSync Display logos.

Supported by the Entire Display Ecosystem

More than two years in development, VESA's Adaptive-Sync Display CTS and logo programs were established with contributions by more than two dozen VESA member companies spanning the display ecosystem, including major OEMs that supply displays, graphic cards, CPUs, panels, display drivers and other components.

In 2014, VESA added Adaptive-Sync protocols to the VESA DisplayPort video interface standard to enable smoother, tear-free images for gaming and jitter-free video playback, as well as enable lower power and greater efficiency in displaying content rendered at a wide range of frame rates. Since this introduction, VESA's Adaptive-Sync technology has seen widespread adoption across the display industry and is now supported by all major GPU chipset vendors. However, while many PC and laptop displays currently support Adaptive-Sync protocols, until now there had been no open standard in measuring the level of performance or quality of Adaptive-Sync support for any given display. VESA's AdaptiveSync Display and MediaSync Display logo programs address this need, providing the consumer with a clear benchmark for front-of-screen visual performance of variable refresh rate operation established by testing in compliance with the Adaptive-Sync Display CTS.

According to Seok Ho Jang , Vice President in charge of IT Development Division at LG Electronics, "We believe that with VESA launching its Adaptive-Sync Display standard in the rapidly growing gaming market, we can expect to see even greater innovation in the gaming monitor categories. We are proud that the LG UltraGear™ brand will be involved from the very beginning with the acclaimed LG UltraGear™ 27GP950 and 27GP850 models, the first-ever monitors to receive VESA AdaptiveSync Display certification. LG also has new 2022 models on the way, which we believe will not only meet the high standards demanded by VESA's performance tests, but are also well equipped to satisfy the expectations and diverse needs of today's consumers."

Comprehensive Validation of Adaptive-Sync Performance

The VESA Adaptive-Sync Display CTS includes more than 50 automated display performance tests covering several key variables, including refresh rate, flicker, gray-to-gray response time (including limits on overshoot and undershoot to ensure high-quality images), video frame drop, and video frame rate jitter. As required by the VESA Adaptive-Sync Display CTS, all displays must be tested in the factory shipping state or default factory mode configuration, as well as tested in ambient room temperature, in order to ensure the display is evaluated and certified under realistic user conditions. In addition, all displays that meet the requirements for VESA AdaptiveSync Display and MediaSync Display logo certification must also be tested and certified to VESA's DisplayPort standard. The majority of desktop and laptop GPUs introduced within the last two years are capable of supporting VESA's Adaptive-Sync protocols. VESA encourages consumers to check with their GPU vendor to verify that their GPU and software driver enables Adaptive-Sync operations with VESA Certified AdaptiveSync Display and MediaSync Display products by default.

Logo Program Qualifies Premium Front-of-Screen Performance Evaluation

The VESA Certified AdaptiveSync Display logo features a performance tier, which includes a value indicating the maximum video frame rate that is achievable for Adaptive-Sync operation tested at the display's factory default settings at native resolution (e.g., AdaptiveSync Display 144 or 240). For the VESA Certified MediaSync Display logo, there is no performance tier since the emphasis of product certification for this logo is on the absence of display jitter rather than high frame rate. Display vendors wishing to participate in the VESA Certified AdaptiveSync Display or MediaSync Display logo program can send their products for testing at any of VESA's approved Authorized Test Centers (ATCs).

According to Roland Wooster , chairman of the VESA Display Performance Metrics Task Group responsible for the Adaptive-Sync Display CTS and the association's representative from Intel Corporation for HDR and Adaptive Sync display technology, "The Adaptive-Sync Display CTS builds upon the foundation that VESA laid with the introduction of the Adaptive-Sync protocols eight years ago. It provides an open, industry-wide and brand-agnostic standard backed by a logo program that gives consumers a guarantee that the displays that they're buying for gaming or for media playback will meet a clearly defined minimum set of front-of-screen performance criteria when used with a suitable GPU. In designing the test specification and logo program, VESA explicitly set a high bar on performance criteria and testing methodology with tighter criteria than many existing specs and logo programs. As with all of our standards, VESA will continue to develop and refine the Adaptive-Sync Display CTS to address new display developments and market needs in order to enable further improvements in visual quality and user-experience for consumers."

Note to Editors: Adaptive-Sync (with a hyphen between Adaptive and Sync) is used for explaining Adaptive-Sync operation and Adaptive-Sync protocols, as well as used to refer to the Adaptive-Sync Compliance Test Specification (Adaptive-Sync CTS). AdaptiveSync (without either hyphen or space) is used to represent the VESA Certified AdaptiveSync logo program. Adaptive Sync (with space between Adaptive and Sync) is a generic term used to refer to variable refresh rate.
