The Video Electronics Standards Association revealed its ‘Adaptive-sync’ technology for its DisplayPort 1.2a interface standard. This will provide smoother, tear-free display that will be appreciated for games and video playback. This is also a good news for AMD’s Project FreeSync and a much easier implementation than Nvidia’s G-Sync.
Adaptive Sync works by enabling a DisplayPort input to match with the refresh rate of the content which varies in gameplay. Nvidia made this very clear when it introduced G-Sync. As they’ve stated, when the graphic card’s framerate output is not in sync with the monitor’s refresh rate, this results to screen tearing.
“DisplayPort Adaptive-Sync enables a new approach in display refresh technology,” said Syed Athar Hussain, Display Domain Architect, AMD and VESA Board Vice Chairman. “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.”
The adaptive sync is available for all of the VESA members without any license fee. As of now, Nvidia has not given any information if this would seize their efforts in working on its G-Sync technology.
Edit (14.05.14) While Nvidia didn’t really give a clear answer, they’ve answered my question with the following answer:
Adaptive-Sync is a protocol not a product. G-SYNC already works over DisplayPort 1.2 today and does not require DisplayPort 1.2a. As far as we know, there are no DisplayPort 1.2a products announced or available. Although there is no license fee or royalty for VESA’s DisplayPort 1.2a specification, as with any technology, there is a cost to develop, implement, and bring products to market. NVIDIA is supportive of industry standards, but not every standard succeeds in the market place. We take a pragmatic approach and support what matters to our customers.
