The Video Electronics Standards Association (VESA) has recently released version 1.1a of the Adaptive-Sync Display Compliance Test Specification (Adaptive-Sync Display CTS). This update introduces revised testing procedures and adds logo support for a new category of variable refresh rate displays. These displays are capable of operating at varying maximum refresh rates contingent on the resolution. The newly introduced "Dual Mode" feature in the specification enables manufacturers with eligible hardware to obtain certification for their products at two distinct resolution and refresh rate combinations, such as 4K/144 Hz and 1080p/280 Hz. This advancement aims to standardize front-of-screen performance for displays with variable refresh capabilities.
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.To date, more than 100 products have been certified to the Adaptive-Sync Display standard. A complete list of Adaptive-Sync Display certified products can be found at https://www.adaptivesync.org/certified-products/.
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, "Until recently, most displays did not have the ability to operate at different refresh rates when the resolution is reduced, instead running at the refresh rate supported by their physical maximum resolution. Users interested in both high-performance gaming as well content creation, photography, or video editing, have often been faced with a difficult choice between purchasing a display with low latency and high refresh rates, or one with higher resolution. Today, more and more displays are coming to market that give users the best of both worlds. VESA's updated Adaptive-Sync Display CTS includes optional testing for these innovative displays, and a new dual mode logo allowing consumers to identify the range of variable refresh rate performance of these displays more easily."
Importantly, none of the testing criteria has changed with the Adaptive-Sync Display v1.1a update. All products that have successfully undergone certification to the prior v1.1 spec are still certified under the latest update. All requirements of the Adaptive-Sync Display CTS, 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, must be met at both tested resolutions, including a minimum of 144 Hz at maximum resolution, and a minimum of 1080p vertical resolution when tested in the reduced resolution/maximum refresh rate mode.
VESA Certified AdaptiveSync Display Logo Changes
For displays that can operate at a faster refresh rate when operated at less than their maximum resolution, the Adaptive-Sync Display v1.1 update allows display OEMs to feature the VESA Certified AdaptiveSync Dual Mode logo on their certified products to represent certification at two speeds and resolutions. On the left side of the logo, the values shown indicate the display's maximum certified refresh rate at maximum native vertical resolution, and the native maximum vertical resolution. On the right side of the logo, the values shown indicate the alternative certified resolution's maximum certified refresh rate and vertical resolution.
According to LG Electronics, LG UltraGear is proud to participate in VESA's Adaptive-Sync Display Dual Mode testing and logo program, and is excited to offer the new Dual Mode feature on its upcoming 32GS95UE OLED gaming monitor. The 'VESA CERTIFIED' logo instantly tells gamers that the 32GS95UE is capable of delivering an optimized gaming experience, whether they're playing graphically rich, story-driven games at UHD 240 Hz, or fast-paced FPS, MOBA or racing games at FHD 480 Hz.
Henry Kong, head of the IT customer experience division of LG Electronics Business Solutions Company, said, "LG Electronics is thrilled to introduce the first-ever gaming monitor to receive VESA's Adaptive-Sync Display Dual Mode certification. With the innovative Dual Mode, gamers can enjoy a greater sense of immersion, with a display performance perfectly tailored to the genre of game they're playing. LG UltraGear will continue to collaborate with VESA to elevate the gaming experience."
According to Vincent Chiou, ASUS corporate vice president and general manager of Display BU, "As pioneers in the gaming monitor industry, we are thrilled to unveil new products with dual-mode technology that will take advantage of VESA's updated Adaptive-Sync Display standard. This dual-mode feature caters to both FPS gamers and immersive gaming enthusiasts alike. At ASUS, we are proud to develop alongside the industry, setting new standards. We believe in pushing boundaries, and dual-mode technology reflects our commitment to providing gamers with the most advanced and immersive experience possible."
