Adaptive Sync

Gaming Monitors

Adaptive syncing in the name given to the technologies
designed at combating screen tearing.

Traditionally with technologies like V-Sync this is achieved by limiting the frame rate to it stays in line with the refresh rate of a monitor. Although this has done a reasonable job for improving the quality of gaming for some, it’s also a limiting factor in a games performance. With newer technologies, faster computing, larger screens with more pixels and faster refresh rates this is becoming less of a viable approach.

In step manufacturers who are currently implementing two new approaches. Both of these approaches shift to using the hardware to tackle the tearing issue. These technologies no longer aim to apply limits to either the monitor display or the frame rate of your game, but instead aim to sync up completed frame rendering with the monitors refresh rate.

G-Sync

G-Sync is Nvidias solution to eliminating screen tearing. It takes the opposite approach to V-Sync and allows the monitor to adapt the framerate of your PC rather than limiting the devices output.
G-Sync is a proprietary technology and to take advantage of G-Sync you must have a G-Sync capable monitor and a graphics card that contains a G-Sync Module. Although the most modern of Nvidia's graphics cards feature this, the monitors available for this usually cost a chunk more compared to their non-G-Sync capable monitor counterpart.

FreeSync

As a response to Nvidia’s G-Sync, FreeSync was developed by AMD, again designed at tackling screen tearing. In 2015 FreeSync was adopted by VESA as an optional component to the DisplayPort 1.2a specification.

FreeSync is royalty free, meaning there should be little or no extra charge for FreeSync enabled monitors, and although currently only AMD offer graphics cards that support it Intel have recently announced they too aim to support VESA’s adaptive sync.
