vertical sync

A feature in modern graphics cards that ensures only full video frames are rendered within one monitor refresh cycle. Video games exhibit varying action, and modern graphics cards can render a variable number of frames per second. Vertical sync (Vsync) eliminates "tearing," in which horizontal sections momentarily appear offset from each other when two sequential frames are rendered in the same refresh cycle. However, with Vsync turned on, time differences between the video frames and monitor refresh cycles can cause the same frame to be displayed twice, creating a brief hesitation ("stuttering"). See adaptive sync and tearing.

NVidia Adaptive Vertical Sync technology virtually eliminates the compromise of stuttering or tearing associated with gaming with or without vertical sync enabled on the Zotac GeForce GTX 680 graphics card by dynamically adjusting VSync to prevent tearing and reduce stuttering for smoother gaming.
The latest addition to Intersil's new high-speed operational amplifier portfolio, the Elantec(R) EL4543 contains embedded logic which encodes standard video horizontal and vertical sync signals onto the common mode of the twisted pair(s), transmitting this additional information without the requirement for additional buffers or transmission lines.
