You’ve probably heard of G-Sync. Maybe you’re interested in getting a new monitor, but aren’t sure if you should get one. If yes, then this blog will be helpful to tell you: what is G-sync.
Either way, I’ll cover everything. My goal with this blog isn’t just to discuss what G-Sync is and the benefits that come with it but I will also discuss tit’s works.
What is G-Sync?
G-Sync is a technology that synchronizes the refresh rate of your monitor with the frame rate of your graphics card. This results in less screen tearing and stuttering when you’re playing games, which can improve your gaming experience. When you’re playing a game, you need to make sure that the graphics card is sending images to the monitor at a good rate.
If it isn’t, there will be visual artifacts like tearing or stuttering. G-Sync helps eliminate these problems by automatically adjusting the refresh rate of your monitor to match the output.
This technology was developed by Nvidia as part of its proprietary G-Sync branding and was introduced into the market in 2013 with the launch of its Kepler architecture GPUs.
All About G-Sync
As you have got a small overview of G-Sync but I don’t want you to be left with any question unanswered. So, let’s discuss in detail.
G-Sync is a way of synchronizing the output of your graphics card with the refresh rate of your monitor.
It’s important because by syncing the two, you can eliminate screen tearing and stuttering that occurs when the graphics card sends frames to the monitor out of sync with what it’s capable of.
This means you’ll get a smoother, more fluid experience while playing games or watching videos than you would without G-Sync enabled.
G-Sync is designed to work with NVIDIA’s GeForce graphics cards, although it can be used with any other kind of graphics card (as long as it supports VESA Adaptive Sync).
It only works on monitors that have a variable refresh rate—they must support adaptive sync technology in order to work properly with G-Sync.
You can find monitors that support adaptive sync technology by looking for models that include “FreeSync” or “Adaptive Sync” in their name or description.

Understanding Display Synchronization
In order to understand G-sync it’s important to first understand what display synchronization is.
According to the research I did, display synchronization is a method of manipulating the display’s refresh rate in order to improve video quality.
The display’s refresh rate is the speed with which it refreshes, or redraws, its image.
Video frames are typically displayed in sequence at a certain speed, but these frames can be displayed at any number of different speeds.
The display’s refresh rate affects how quickly the image appears on-screen and whether there are any visible flickers or blurs in its movement.
A lower refresh rate means that each frame will be displayed for longer, which can cause motion blur and flicker.
A higher refresh rate means that each frame will be displayed for less time; this can make moving images appear more crisp and clear but will also cause flickering if they move too fast.
The Evolution of G-Sync Technology
G-Sync was first introduced in 2013 with the launch of Nvidia’s Kepler architecture. At the time, it was called Adaptive Sync.
The technology has undergone several evolutions since then, and now it is known as G-Sync 2. The latest iteration of the technology is G-Sync 3, which was announced in March 2019.
Here’s I stated two early version of Nvidia’s adaptive sync technology and how they compare to each other:
- G-Sync 1
This version was available on high-end monitors that were manufactured by Acer, ASUS, BenQ and Philips.
It offered a 4:4:4 color sub-sampling mode that provided better quality than standard display modes.
However, this mode only worked at 30Hz or above, so it wasn’t ideal for gamers who wanted to use their monitors at higher refresh rates (higher than 60Hz).
- G-Sync 2
This version of adaptive sync technology supported more than one monitor per computer.
It also allowed for variable overdrive (VOD), which improved motion clarity by reducing ghosting effects when using lower refresh rates than normal (e.g., 30Hz).
It also added support for HDR (high dynamic range) content on compatible displays.

How Does G-Sync Work?
According to the research I did, NVIDIA G-Sync is an adaptive display technology that synchronizes a graphics card’s refresh rate with the monitor’s refresh rate.
This is done through a hardware module that’s installed on the graphics card and a driver that works with the operating system to adjust the display whenever you change games.
When you play games, the graphics card sends data to your monitor at a certain speed.
If your monitor has a 60 Hz refresh rate and you’re playing a game that requires it to update more often than once every 16.7 milliseconds, some frames may be missed.
With G-Sync technology, if your graphics card can’t keep up with your monitor’s refresh rate, it will automatically reduce its frame rate until it can catch up again.
This allows for smoother gameplay and eliminates screen tearing when running games at high frame rates or resolutions higher than 1080p.
