The Video Electronics Standards Association (VESA) today announced the addition of 'Adaptive-Sync' to its popular DisplayPort 1.2a video interface standard. This technology delivers several important capabilities to computer users: Adaptive-Sync provides smoother, tear-free images for gaming and judder-free video playback. It also significantly reduces power consumption for static desktop content and low frame rate video.

Computer monitors normally refresh their displays at a fixed frame rate. In gaming applications, a computer's CPU or GPU output frame rate will vary according to the rendering complexity of the image. If a display's refresh rate and a computer's render rate are not synchronized, visual artifacts-tearing or stuttering-can be seen by the user. DisplayPort Adaptive-Sync enables the display to dynamically match a GPU's rendering rate, on a frame-by-frame basis, to produce a smoother, low latency, gaming experience. In applications where the display content is static-such as surfing the web, reading email, or viewing a slide presentation-DisplayPort Adaptive-Sync allows the display refresh rate to be reduced seamlessly, lowering system power and extending battery life.
