The VESA Adaptive-Sync Display Compatibility Test Specification establishes a clear standard for consumers to compare the variable refresh rate performance of displays that support the VESA Adaptive-Sync protocol.
The Video Electronics Standards Association (VESA®) announced the first published open standard for front-screen performance of variable refresh rate displays. The VESA Adaptive-Sync Display Compliance Test Specification (CTS) provides a set of up to 50 complete and rigorous test criteria and automatic test methods for PC monitors and notebook computers that support the VESA Adaptive-Sync protocol. , and performance requirements.
Adaptive-Sync Display CTS has also established a product compatibility label program with two test levels, one for higher update rates for games and one for low latency.AdaptiveSync Display; and designed to support jitter-free media playback of all international broadcast video formatsMediaSync Display. By establishing the VESA-certified AdaptiveSync Display and MediaSync Display logo programs, VESA helps consumers easily identify and compare the variable refresh rate performance of Adaptive-Sync-enabled displays before purchasing. Only monitors that pass all Adaptive-Sync Display CTS tests for compatibility with VESA DisplayPort™ can bear the VESA Certified AdaptiveSync Display or MediaSync Display badge.
Supported by the entire display ecosystem
The VESA Adaptive-Sync Display CTS and Badge program has been in development for over two years with support from over 20 VESA member companies across the display ecosystem, including supplying monitors, graphics cards, CPUs, panels, monitors Large OEM of drivers and other components.
VESA added the Adaptive-Sync protocol to the VESA DisplayPort video interface standard in 2014 to achieve smoother, tear-free game images and jitter-free video playback, as well as improved display content rendered at various frame refresh rates. Low power consumption and higher efficiency. VESA’s Adaptive-Sync technology has been widely adopted by the display industry since its introduction and is now supported by all major graphics processing unit (GPU) chipset manufacturers. Nonetheless, while many PC and notebook monitors currently support the Adaptive-Sync protocol, until now there has been no open standard for measuring the performance and quality of specific monitors that support Adaptive-Sync. VESA’s AdaptiveSync Display and MediaSync Display badge programs not only meet this need, but also provide consumers with a clear standard for in-screen visual performance running at variable refresh rates through testing in compliance with the Adaptive-Sync Display CTS.
Seok Ho Jang, Vice President of IT Development at LG Electronics, said, “We believe we can expect to see more innovations in the gaming monitor category as VESA rolls out the Adaptive-Sync Display standard in the fast-growing gaming market. We Very proud of the well-received LG UltraGear™ 27GP950 and 27GP850 product models under the LG UltraGear™ brand, which will be the first monitors to be VESA AdaptiveSync Display certified. LG will also be launching new 2022 models, we believe The new model will not only meet the high standards set by VESA performance testing, but also meet the expectations and diverse needs of today’s consumers.”

The VESA Adaptive-Sync Display Compliant Test Specification includes up to 50 automated display performance tests covering key variables such as update rate, flicker, grayscale response time (including limiting overshoot and undershoot to ensure high quality) video), video frame rate drop and jitter. As required by the VESA Adaptive-Sync Display CTS, all displays must be tested in the factory-as-shipped condition or in the default factory mode configuration, and must also be tested at ambient room temperature to ensure the Accept evaluation and certification under real usage scenarios. In addition, all monitors certified to the VESA AdaptiveSync Display and MediaSync Display logos are also tested to achieve VESA DisplayPort standard certification. Most desktop and laptop GPUs released in the past two years support the VESA Adaptive-Sync protocol. VESA encourages consumers to check with GPU manufacturers to ensure that their GPU and software drivers are preset to allow Adaptive-Sync operation of VESA-certified AdaptiveSync Display and MediaSync Display products.
Badge program meets top-notch in-screen performance evaluation criteria
The VESA-certified AdaptiveSync Display badge provides a performance tier that includes a numerical value representing the maximum the display can achieve for Adaptive-Sync operation when tested at native resolutions (such as AdaptiveSync Display 144 or 240) once morest factory defaults. Video frame update rate. As for the VESA-certified MediaSync Display badge, there is no performance tier provided because the badge’s product certification focuses on display jitter-free display rather than high frame refresh rates. Display manufacturers who want to join the VESA-certified AdaptiveSync Display or MediaSync Display logo programs can send their products to any VESA-approved Authorized Test Center (ATC) for testing.

Roland Wooster, head of the VESA Display Performance Metrics task group in charge of Adaptive-Sync Display CTS and VESA resident representative of Intel’s HDR and Adaptive Sync display technologies, said: “Adaptive-Sync Display CTS is built on the Building on the foundation laid by the Adaptive-Sync Agreement, it provides an open, industry-wide, brand-agnostic, program-endorsed standard that ensures consumers purchase monitors for gaming or media playback with the right fit. When designing a GPU, it can at least meet a set of well-defined in-screen performance criteria. VESA clearly sets extremely high standards in terms of performance criteria and test methods when designing test specifications and labelling programs. Many existing specifications and labeling programs have become more stringent. VESA will continue to develop and improve the Adaptive-Sync Display CTS to respond to new display developments and market demands, and to further enhance the visual quality and user experience for consumers.”
