DisplayPort (DP) version 1.2, launched in 2010, brought several enhancements to the standard for monitor connections. The update increased the maximum data rate, allowed higher resolutions and refresh rates, and supported multiple screens through MST. It also included support for 3D and improved synchronization between audio and video. DisplayPort Version 1.2a, released in 2013, included Adaptive Sync, from which AMD's advanced FreeSync derived. Adaptive Sync was later integrated as an optional feature in the DisplayPort standard.
