In order to use G-Sync, you need to use a Display-Port cable between your Y27g / RE Monitor and your nVidia Graphics Card:




Upon starting your PC and adjusting the desired Refresh Rate of your Monitor (the Y27g / RE are capable of refresh rates up to 144Hz), go to the nVidia Control Panel via right click on your Desktop. Under Display, select G-SYNC as shown below and check "Enable G-SYNC", which will be running next time you start up a game:




Don't forget that while using G-Sync, its pointless to have Vertical Synchronization enabled in-game, so we recommend leaving this option turned off to not interfere and limit your performance and G-Sync itself.
