How to enable Nvidia G-Sync on PC

Nvidia G-Sync modifies the refresh rate of your monitor to provide a smooth, seamless gameplay experience. If you have one of the best G-Sync monitors, you’ll need to know how to enable G-Sync on a PC. And in this guide, we’re going to show you how.

Got an AMD graphics card or a Freesync monitor instead? Here’s how to enable Freesync.

How to enable Nvidia G-Sync on PC

Before getting to how to enable G-Sync, you need to make sure you have a G-Sync monitor. Nvidia has a few different G-Sync categories. G-Sync and G-Sync Ultimate monitors come with dedicated hardware inside that handles the variable refresh rate, and they’re typically more expensive than other monitors. There are also G-Sync Compatible monitors, which don’t have dedicated hardware but still support Nvidia’s adaptive refresh feature.

You also need an Nvidia graphics card. As long as you have everything you need, hook up your monitor, update your graphics card drivers, and install the latest version of Nvidia Control Panel. From there, enabling G-Sync is simple:

Step 1: Open the Nvidia Control Panel.

Step 2: Expand the Display tab and select Set Up G-Sync. 

Step 3: Check Enable G-Sync, G-Sync Compatible. 

Step 4: Select either Enable For Full Screen Mode or Enable for Windowed and Full Screen Mode depending on what you want.

Step 5: Click Apply.

Using multiple monitors with G-Sync

If you have multiple monitors, you’ll see a few more settings on the page. You can apply G-Sync settings to a specific display if you choose, which can be useful in a few different situations. If your primary display supports G-Sync, for example, but your secondary display doesn’t, you can apply the setting only to a single display.

If that’s what you want to do, follow these additional steps:

Step 1: Select the display you want to update.

Step 2: Check Enable Settings for the Selected Display Model. 

Step 3: Click Apply. 

You also need to make sure the display you’re applying the settings to is your primary display. To do that, head to System > Display in Windows, select your primary display, and then check Make This My Main Display.

After you’ve done that, you’ll want to double-check that your monitor is set to use G-Sync instead of a fixed refresh rate. In the Nvidia Control Panel, take these steps:

Step 1: Expand the 3D Settings tab and select Manage 3D Settings. 

Step 2: Under the Global Settings tab, find the Monitor Technology setting.

Step 3: Change the setting from Fixed Refresh Rate to G-Sync. 

Step 4: Click Apply. 

That’s it. Whenever you load up a game, you’ll be able to use variable refresh rate as long as you have a compatible display. In most cases, you don’t need to do anything on your monitor. However, some displays come with a toggle in the settings for G-Sync, so make sure to turn that on, as well.

Here’s how Nvidia defends its RTX 4060 Ti’s memory controversy
nvidia rtx 4060 ti 8gb 16gb memory controversy nvidia02

The rumors are true: Nvidia has two versions of its new RTX 4060 Ti graphics card. These are the highly anticipated new midrange GPUs, and yes, one comes with 8GB of VRAM and one comes with 16GB -- and they're separated by $100 in price.

It's a head-scratching decision on a few different levels. Games that demand more than 8GB of VRAM are increasingly common, which is frustrating for those eying the $399 8GB model. What's more -- the RTX 4070 Ti comes with just 12GB of VRAM, despite costing $599.

With the RTX 4060 at $299, Nvidia reverses course on pricing

Price increases have been the name of the game for Nvidia's RTX 40-series cards so far, but the introduction of the RTX 4060 family attempts to reverse course.

The RTX 4060 Ti 8GB comes in at $399, matching the retail price of the 3060 Ti, while the 4060 Ti 16GB costs $100 more. But the RTX 4060 is where the real value's at this time around. It will retail in July for just $299, undercutting the previous-gen RTX 3060 by $30 and the RTX 2060 by $50. It hasn't been since the GTX 1060 Founders Edition launched in 2016 that we've seen prices this low.

The best PC builds: budget, gaming, video editing, and more

PC building is fun, but it's also a bit scary. After all, it's hardly cheap -- you're going to spend hundreds or thousands of dollars on something that will hopefully last you for years.

So, you need to know exactly what type of PC you're building and be realistic about what it'll be capable of. It's not as simple as buying a pre-built PC, and we could never give a recommendation for every budget and every specific scenario. But hopefully, these example builds give you a good place to start, especially if you aren't sure exactly how everything fits together.
