The Video Electronics Standards Association (VESA) has confirmed that Adaptive-Sync is now an official feature of the DisplayPort 1.2a video interface standard for external monitors, promising that products including the feature will be appearing on the market soon.
Adaptive-Sync, added to the Embedded DisplayPort (eDP) standard in 2009 but missing from the full-fat DisplayPort standard until now, is equivalent to Nvidia's G-Sync technology
: the refresh rate of the connected display is dynamically altered to match the content being displayed. For gamers, it means smooth motion with no tearing or stuttering; for those viewing more static content such as web pages or documents, it means reduced power draw - hence its inclusion in eDP for mobile devices to use. It's related to AMD's FreeSync
, which was donated to the VESA group several years before the technology was made public.
'DisplayPort Adaptive-Sync enables a new approach in display refresh technology,
' claimed Syed Athar Hussain, Display Domain Architect at Nvidia rival AMD and VESA board vice chair. 'Instead of updating a monitor at a constant rate, Adaptive-Sync enables technologies that match the display update rate to the user’s content, enabling power efficient transport over the display link and a fluid, low-latency visual experience.
Being a formal part of the standard, DisplayPort Adaptive-Sync - as the technology is now known - will come with a full suite of compliance testing and a certification system to guarantee compatibility between DisplayPort Adaptive-Sync graphics chips and external displays. The technology is also being offered to all VESA members - including Nvidia - free of charge, potentially helping to boost adoption of the technology above and beyond Nvidia's proprietary equivalent.
Although VESA has indicated that DisplayPort Adaptive-Sync is ready to deploy, neither the group itself nor its member companies have yet indicated when we'll be seeing the first official products hitting shop shelves.
