In a press release, the Video Electronics Standards Association announced the addition of 'Adaptive-Sync' to its DiplayPort video interface. It promises smooth, tear-free, and stutter-free video. Additionally, it also boasts power consumption reduction.
"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," the release reads.
"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," the power reduction is further explained.
VESA is an internation non-profit standards association that represents more than 200 hardware and software manufacturers in the electronics industry. One of the association's standard include the DisplayPort which they claim is the industry replacement for DVI, LVDs, and VGA.
