FreeSync
Definition
AMD branding for variable refresh rate display technologies.
Detailed explanation
FreeSync is AMD branding for variable refresh rate displays based largely on VESA Adaptive-Sync. Product tiers can add low-framerate compensation or HDR requirements. FreeSync capability depends on the monitor, link, GPU, driver, and frame-rate range; it is not a frame-generation technology. Adaptive-Sync timing lets a compatible display vary vertical blanking intervals around frame delivery. FreeSync Premium and Premium Pro add certification requirements beyond the base label, so two marketed displays can differ in refresh range, low-frame-rate behavior, latency, and HDR processing.
