What is G-SYNC, and what does it do?
G-Sync refers to a display technology used in PC and gaming monitors. G-SYNC technology is designed to improve graphical performance and curtail screen tearing or stuttering, particularly in gaming laptops when playing fast-paced games or videos. For G-SYNC to get working properly, it is important to connect the display to a system having a compatible computer's graphics card (Nvidia or third party G-SYNC compatible GPU)
G-SYNC also reduces stuttering because it allows the monitor to display each frame for the same amount of time. This means that each frame is displayed for the same amount of time, which eliminates stuttering. Input lag is the time it takes for your input to be displayed on the screen. G-SYNC reduces input lag by allowing the monitor to display each frame as soon as it's ready. This means that your input is displayed on the screen as soon as it's ready, which reduces input lag.
G-SYNC is available on select monitors from Acer, ASUS, BenQ, LG, NEC, and Samsung. G-SYNC modules are also available from NVIDIA.
How to check if G-SYNC is enabled
If you are an active gamer, who plays fast-paced games or want to reduce tearing on your monitor, you need to enable G-SYNC.
To check if it's actually enabled on your PC, you to the Nvidia Control Panel and under “Display” you should see “Setup G-SYNC”. Click on that to see if G-SYNC has been enabled for your system.
If it's not enabled, simply checkmark the “Enable G-SYNC, G-SYNC Compatible” field and select “Enable for full screen mode”.
If you want to test if G-SYNC is working properly you can download one of the Nvidia G-SYNC demos here and run it: https://www.nvidia.com/en-us/geforce/community/demos/#!/g-sync
