A není to náhodou taky tak, že jakýkoliv FreeSync monitor splňuje i VESA Adaptive Sync?
FreeSync podporuje synchronizaci přes DP a HDMI, Adaptive Sync jen přes DP.
Wiki:
VESA announced Adaptive-Sync as an ingredient component of the DisplayPort 1.2a specification; FreeSync is a hardware–software solution that uses DisplayPort Adaptive-Sync protocols to enable smooth, tearing-free and low-latency gameplay.[5] FreeSync has also been implemented over HDMI.
