VESA launches the industry’s first open standard and logo program for PC monitor and laptop display variable refresh rate performance
The AdaptiveSync Display CTS also designates a product compliance logo program containing two performance tiers: AdaptiveSync Display, which is concentrated on gaming with exceptionally higher refresh rates and lower latency. Media sync Display, developed for jitter-free playback of media, helped all multinational broadcast video configurations by establishing the VESA Certified AdaptiveSync Display and MediaSync Display logo programs. The VESA Certified AdaptiveSync Display logo is developed for gaming monitors, concentrated on higher refresh rates and low latency panel performance. The logo contains a value exhibiting the highest video frame rate attainable for the AdaptiveSync procedure when experimented with manufacturer default settings at native resolution—values in the logo comprising 144, 165, 240, 360, and higher. Vendors wishing to partake in the VESA Certified AdaptiveSync Display or MediaSync Display logo program can send their products for testing at VESA’s approved Authorized Test Centers (ATCs). VESA will allow customers to effortlessly recognize and compare displays’ varying refresh rate performance supporting AdaptiveSync before buying. Only displays that pass all AdaptiveSync Display CTS and VESA DisplayPort™ compliance tests can authorize for the VESA Certified AdaptiveSync Display or MediaSync Display logos. The VESA Certified MediaSync Display logo is developed for displays predominantly focused on jitter-free media playback backing all global broadcast video formats. This logo has no performance tier since product certification focuses on the lack of jitter and flicker instead of an elevated frame rate. VESA’s AdaptiveSync Display CTS and logo programs were founded with assistance by more than two dozen VESA member organizations traversing the display ecosystem, including prominent OEMs that provide displays, graphic cards, CPUs, panels, display drivers, and other components. VESA added AdaptiveSync protocols to the VESA DisplayPort video interface standard to enable smoother, tear-free images for gaming and jitter-free video playback. And the new standards allow lower power and greater efficiency in displaying content rendered at a wide range of frame rates as early as 2014. Since then, VESA’s AdaptiveSync technology has seen widespread adoption across the industry and is currently supported by all significant GPU chipset vendors. While many PC and laptop displays currently support AdaptiveSync protocols, there has not been an open standard in calculating the level of performance or quality of AdaptiveSync support for displays. VESA’s AdaptiveSync Display and MediaSync Display logo programs manage this demand, supplying the buyer with a specific benchmark for front-of-screen visual performance of variable refresh rate operation verified by testing in compliance with the AdaptiveSync Display CTS. The VESA AdaptiveSync Display CTS incorporates over 50 automated display performance tests covering a few key factors: refresh rate, flicker, and gray-to-gray response time (remembering limits for overshoot and undershoot to guarantee top-notch pictures), video frame drop, and video frame rate jitter. — Seok Ho Jang, Vice President in charge of the IT Development Division at LG Electronics The VESA AdaptiveSync Display CTS expected that all monitors be tested in the industrial facility shipping state or default factory mode configurations and tested in encompassing room temperature environments before shipping. Furthermore, all displays that meet VESA AdaptiveSync Display and MediaSync Display logo confirmation requirements should likewise be tried and ensured to VESA’s DisplayPort standard. Most of the laptop and PC GPUs presented in the most recent two years are equipped for supporting VESA’s AdaptiveSync conventions. VESA urges buyers to check with their GPU merchant to confirm that their GPU and programming driver automatically empowers Adaptive-Sync activities with VESA Certified AdaptiveSync Display and MediaSync Display items. —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
