What is G-Sync? [COMPLETE GUIDE]

When it comes to gaming, the video quality of your monitor makes all the difference in the world. It is essential that the monitor doesn’t lag during the game, doesn’t tear and the refresh rate should be high.

While we all know that the lower the resolution, the higher the refresh rate, a low-resolution video is not at all desirable. In the era of 8k resolution, people would seldom want to opt for a monitor with low resolution.

The question that arises here is why one needs to choose between better image quality and the refresh rate, why can’t we have both?

To make sure that one is getting the most out of everything, new technological advancements have improved the gaming experience and taken it to the next level.

G-Sync is one such technological advancement that everyone needs to be aware of. What is precisely G-Sync and how does it work.

What is G-Sync?

G-Sync technology is used in LCDs (liquid crystal displays) and display monitors. It’s an adaptive synchronization technology. A G-Sync monitor uses this technology to get rid of stuttering screen tearing by synchronizing the graphics card frame rate (FPS) with the refresh rate.

Monitors that have G-Sync technology have a new alternative up-gradation that matches the graphic card frame rate and is called variable refresh rate (VRR). In order to understand the basic idea of G-Sync, you need to know about basic malfunction issues regarding G-Sync i.e., screen tearing, V-synch, and stuttering.

 With the assistance of NVIDIA G-Sync, there will be no complaints of screen tearing or stuttering. To get facilitated with this new G-Sync technology, customers will need a G-Sync compatible monitor and a G-Sync-well-compatible graphics card.

How Does G-Sync Work?

For understanding the basic idea of G-Sync and its workings, you have to understand how an image is generated by the workings of a graphic card and monitor.

However, the frames are extracted and sent by GPU for display. For creating the picture those frames are refreshed a specific number of times. Different frequencies are available for that.

The screen tearing occurs when the GPU sends additional frames per second to your display when a display has a low refresh rate. This puts a load on your display and disfigured display that results in screen tearing. 

You can purge screen tearing by permitting the V-SYNC option in your drivers and video game settings. Until the monitor is ready for display the GPU keeps the frames in wait. This effectively removes screen tearing and keeps the frame rates in check, thus, maintaining the synchronized affiliation.

However, in a condition, if the card is unable to extract frame rate before the next refresh rate, a specific kind of lag occurs, called supplementary input lag. Thus, producing a kind of screen anomaly called stuttering.  In the end, you can either choose between screen tearing with lower input lag i.e., V-synch off, or screen tearing at the expanse input lag with V-synch on.

This is exactly where G-Sync kicks in and forces the GPU and the display to work in perfect agreement within reach of a certain refresh rate. It’s possible that by the usage of CRU third party we can effectively increase the dynamic range of refresh rate and CRU stands for Custom Resolution Utility.

Some G-Sync video display units feature the LFC technology, which will increase the refresh rate when your FPS drops below the lower end of the range, thus preserving an evener tear-free performance.

For instance, in case your FPS drops to 35 FPS, LFC will modify the display’s refresh rate to 70 Hz on a 74Hz monitor for seamless performance.

All monitors that have a variable refresh rate range of at least 2:1 (for instance, 50Hz-100Hz) automatically support LFC. So, if you are looking for a G-Sync monitor, you should look for a wide variable refresh rate range and LFC support.

Frequently Asked Questions (FAQs)

What Do I Need to Get G-Sync to work?

For utilizing the free sync facility, you need a well-matched AMD graphics card or integrated APU system, a well-suited and qualified monitor, and a DisplayPort or HDMI connection. The previous VGA and DVI connections are mismatched.

Which G-Sync Monitor Should You Buy?

The monitors that have a specific refresh rate range of a minimum of 2:1 (for instance, 50Hz-100Hz) will inevitably support LFC. To buy the best free sync monitor, you should go with a wide range of refresh rates.

Is G-Sync Worth it For Gaming?

Yes! It is worth it. All you need is an NVIDIA video card and G-Sync compatible  monitor. These two allow you to dynamically play and the perfect refresh rate.


In conclusion, to stop your screen from tearing and stuttering too in the middle of having an intense gaming session with your pals, you need a high-end synchronicity device or an application. Now what this specific application will do is synchronize its refresh rate with the graphics card frame rate (FPS). You might have gone above and beyond for a high-end graphics card, which most gamers do, you are not alone. But they forget a vital point here. A synchronicity device.

This synchronicity application will synchronize forcefully to make your FPS match the rate of your display’s refresh rate. AMD free sync technology does this very specific work for you. There are three tiers to this application. For best results buy the premium pro tier. I hope this explained all your questions. Now you know what G-Sync is and what is the version to buy out there.
