What does it mean when there are FreeSync, FreeSyncPremium, and Adaptive-Sync in the monitor menu?

When the input source is DP, the monitor menu displays FreeSync Premium; when the input source is HDMI, the monitor menu displays Adaptive-Sync. freesync premium is for AMD and Adaptive-sync is for VESA (Video Electronics Association). The actual functions of the two are the same, but the display names are different because they correspond to different organizations. The functions are the same but the names are different. The support of multiple standards can make the products more compatible.
Note: (Due to the update of AMD certification standards, the product certification method has been refined. FreeSync may be displayed in the menu of some batches of products. To ensure better compatibility of products in complex environments, we support multiple refreshes under different ports. Rate synchronization technology. DisplayPort Adaptive-Sync (Adaptive-Sync) is a new feature of the DisplayPort 1.2a specification. It was proposed by AMD to the VESA team and transplanted based on the embedded DisplayPort v1.0 specification. DisplayPort Adaptive-Sync ( Adaptive-Sync) is an important feature of the DisplayPort port and an industry standard, enabling technologies such as AMD FreeSync (Intelligent Display for Gaming) to adjust the monitor refresh rate in real time. AMD FreeSync (Game Intelligent Display) technology is an innovative AMD hardware/software solution that greatly reduces input latency through the DisplayPort Adaptive-Sync protocol and reduces or completely eliminates stuttering and stuttering when playing games and videos. The phenomenon of screen blur and tearing has fundamentally solved the problems faced by the majority of users. Adaptive-Sync monitors enable the graphics card and APU (Accelerated Processing Unit) to directly and dynamically control the refresh rate of the monitor connected to it. It can avoid obvious misalignment/tearing in the picture at high frame rates. Adaptive-Sync is an extension of FreeSync and needs to be connected to a DP1.2 cable and a graphics card of GTX10 series or above. The software requires WIN10 system, and the graphics card driver needs to be updated to version number 417.71. NVIDIA's NVIDIA gaming graphics cards are compatible with FreeSync/AdaptiveSync and the restrictions are the same as AdaptiveSync.
