Learning how to enable G-Sync or FreeSync on a monitor is one of the simplest upgrades a gamer can make, since it removes screen tearing and smooths out choppy frame pacing without touching any hardware. The feature only works when the monitor, the cable, and the graphics driver are all set up correctly, and missing one of those pieces is the most common reason it does not turn on. This guide walks through the exact settings to check and change on both NVIDIA and AMD systems.
Key Takeaways
- G-Sync and FreeSync must be enabled in two places: the monitor’s on-screen display menu and the graphics driver software.
- NVIDIA users enable the feature through the NVIDIA Control Panel under ‘Set up G-SYNC’.
- AMD users enable it through AMD Software: Adrenalin Edition under the Display tab.
- A DisplayPort connection generally offers the most reliable variable refresh rate support, though many modern monitors also support it over HDMI.
- Outdated graphics drivers are a frequent cause of the option being missing entirely, so updating the driver first saves troubleshooting time later.
Before You Start
This is a software adjustment, not a hardware repair, so no disassembly or power-down is required. A few quick checks beforehand make the process go smoothly.
- Confirm the monitor actually supports G-Sync or FreeSync by checking the product specs or the box it came in.
- Use a DisplayPort cable where possible, since it has historically offered the widest and most stable variable refresh rate support across brands.
- Update the graphics driver to the latest version through NVIDIA GeForce Experience, the NVIDIA website, or AMD Software, since older drivers sometimes hide the setting entirely.
- Make sure the monitor is connected directly to the graphics card output, not to a motherboard video port, since onboard graphics will not display the option.
Tip: If the monitor is running through a docking station, USB-C hub, or KVM switch, plug it directly into the graphics card first to rule out a compatibility issue with the middleman device.
How to Enable G-Sync
Step 1: Turn on G-Sync in the Monitor’s OSD Menu
Many G-Sync Compatible monitors ship with the feature switched off by default. Open the monitor’s on-screen display using its physical buttons and look for a setting labeled ‘G-Sync’, ‘Adaptive Sync’, or ‘Variable Refresh Rate’, then switch it on. The exact wording and menu location vary by monitor brand.
Step 2: Enable G-Sync in the NVIDIA Control Panel
- Step 1: Right-click on the desktop and select ‘NVIDIA Control Panel’.
- Step 2: In the left sidebar, click ‘Display’, then select ‘Set up G-SYNC’.
- Step 3: Check the box for ‘Enable G-SYNC, G-SYNC Compatible’.
- Step 4: Choose whether to apply it to full screen mode only or to full screen and windowed mode, depending on preference.
- Step 5: Click ‘Apply’ to save the change.
Step 3: Confirm It Is Active
Under ‘Set up G-SYNC’ in the Control Panel, a confirmation message should appear stating that the display supports G-Sync. This works best when the monitor is plugged directly into the discrete GPU output rather than a motherboard port.
How to Enable FreeSync
Step 1: Turn on FreeSync in the Monitor’s OSD Menu
Just like G-Sync, FreeSync often needs to be switched on manually in the monitor menu before the graphics card can use it. Look for ‘FreeSync’, ‘AMD FreeSync’, or ‘Adaptive Sync’ in the display settings section of the OSD.
Step 2: Enable FreeSync in AMD Software
- Right-click the desktop and open ‘AMD Software: Adrenalin Edition’.
- Click the ‘Display’ tab along the top menu.
- Toggle ‘AMD FreeSync’ to the on position.
- Restart the display or the PC if the setting does not take effect immediately.
Step 3: Verify the Refresh Rate Matches
Open the Windows display settings and confirm the refresh rate is set to the monitor’s maximum supported rate. FreeSync works within a range, so running at a very low manually forced refresh rate can limit how well it performs.
Tip: Most people find that leaving the refresh rate on ‘highest available’ in Windows lets FreeSync manage the range automatically, rather than locking it to one fixed number.
Common Problems and Fixes
The Option Is Missing From the Driver Software
This usually means the driver is outdated or the monitor is not connected to the discrete GPU. Update the driver through the manufacturer’s official software, and double-check the cable is running from the monitor straight into the graphics card, not the motherboard.
Screen Flickering or Brightness Flashing After Enabling It
Some monitors flicker at the low end of their variable refresh rate range, particularly in dim scenes. Updating the monitor’s firmware if the manufacturer offers it, or switching from HDMI to DisplayPort, often resolves this.
G-Sync or FreeSync Enabled But Tearing Still Happens
This is often caused by a game’s in-game V-Sync setting conflicting with the driver-level setting, or a frame rate that exceeds the monitor’s max refresh rate. Enabling V-Sync in the NVIDIA Control Panel or AMD Software alongside G-Sync or FreeSync, or capping the frame rate slightly below the monitor’s refresh rate, typically fixes this.
Feature Grayed Out in the Control Panel
A grayed-out option almost always points to a cable or port issue. Try a different DisplayPort or HDMI cable, and confirm the specific port being used on the monitor actually supports variable refresh rate, since not every port on a monitor does.
Frequently Asked Questions
What is the difference between G-Sync and FreeSync?
G-Sync is NVIDIA’s variable refresh rate technology and FreeSync is AMD’s version. Both aim to sync the monitor’s refresh rate with the graphics card’s frame output to eliminate tearing, though they use different certification standards and hardware requirements.
Can a FreeSync monitor work with an NVIDIA graphics card?
Many FreeSync monitors work with NVIDIA cards through NVIDIA’s ‘G-Sync Compatible’ certification, which validates FreeSync monitors for use with G-Sync. This is enabled through the same ‘Set up G-SYNC’ menu in the NVIDIA Control Panel.
Does enabling G-Sync or FreeSync reduce frame rate?
No, it does not reduce raw frame rate. It changes how frames are delivered to the display to reduce tearing and stutter, and any perceived difference is usually related to V-Sync settings used alongside it.
Why is there no G-Sync or FreeSync option in the driver menu?
This typically means the monitor is not connected to the discrete GPU, the cable does not support variable refresh rate, or the driver needs an update. Checking the connection and updating the driver resolves this in most cases.
Does the cable type matter for G-Sync or FreeSync?
Yes. DisplayPort has traditionally offered the most consistent support across monitor brands. Many newer monitors also support variable refresh rate over HDMI, but it is worth confirming in the monitor’s specifications first.
Should G-Sync or FreeSync be used with V-Sync at the same time?
Using both together is a common setup and helps prevent tearing above the monitor’s refresh rate ceiling. Setting a frame rate cap slightly below the monitor’s max refresh rate alongside this combination gives the smoothest result.
Can G-Sync or FreeSync be enabled on a laptop?
Yes, if the laptop’s built-in display and graphics card both support it. The setting is usually found in the same NVIDIA Control Panel or AMD Software menus, though some laptops also require enabling it in a manufacturer-specific utility.
Why does the screen flicker after turning on FreeSync or G-Sync?
Flickering at low frame rates is a known limitation on some monitor panels, especially in darker scenes. A firmware update from the monitor manufacturer or switching to a different port can often reduce or eliminate it.
Is a special monitor required to use these features?
Yes, the monitor needs to support G-Sync, G-Sync Compatible, FreeSync, or Adaptive Sync at the hardware level. This information is listed in the monitor’s official specification sheet.
