While AMD wasn’t the first GPU vendor to implement a system for variable refresh, the company has made up for lost time with zeal. Since demonstrating their FreeSync proof-of-concept laptop demo back at CES 2014, AMD has since been able to get the necessary signaling and refresh technology implemented into the DisplayPort standard as an optional annex of 1.2a, more commonly known DisplayPort Adaptive-Sync. With DPAS implemented into monitors, AMD has been able to roll out their FreeSync implementation of variable refresh back in March of this year, when the first DPAS-enabled monitors shipped.
