Adaptive-Sync is a required component of AMD’s FreeSync, which allows the monitor to vary its refresh rate based on input from the GPU. DisplayPort is a universal and open standard, supported by every modern graphics card and most modern monitors. However, it should be noted that while Adaptive-Sync is considered part of the official VESA specification for DisplayPort 1.2a and 1.3, it is important to remember that it is optional. This is important because it means that not all new displays utilizing DisplayPort 1.3 will necessarily support Adaptive-Sync.
