How to Check Whether a Monitor Supports G-Sync or FreeSync

Modern gaming monitors often advertise support for NVIDIA G-Sync or AMD FreeSync, two adaptive sync technologies designed to deliver smoother gameplay. These technologies help eliminate screen tearing, reduce stuttering, and improve overall visual performance. However, not all monitors truly support these features, and some only work under specific conditions.

This article provides a complete and practical guide on how to check whether your monitor supports G-Sync or FreeSync, both from specifications and through real-world testing.

Understanding G-Sync and FreeSync

Before checking monitor compatibility, it is important to understand the difference between these two technologies.

What Is NVIDIA G-Sync?

G-Sync is an adaptive sync technology developed by NVIDIA. It synchronizes the monitor’s refresh rate with the GPU’s frame rate, resulting in smoother motion and reduced input lag.

There are several types of G-Sync support, including G-Sync Compatible, G-Sync, and G-Sync Ultimate.

What Is AMD FreeSync?

AMD FreeSync is AMD’s adaptive sync technology based on the VESA Adaptive-Sync standard. It works with compatible GPUs to dynamically adjust the monitor’s refresh rate.

FreeSync is widely supported and available in different levels such as FreeSync, FreeSync Premium, and FreeSync Premium Pro.

Check the Monitor’s Official Specifications

The first and most reliable method is checking the monitor’s official specifications.

• Visit the manufacturer’s official website
• Search for your monitor model number
• Look for G-Sync or FreeSync information in the features section

If the monitor officially supports G-Sync or FreeSync, it will be clearly stated in the product specifications.

Check the Monitor Box and User Manual

If you still have the original packaging, check the monitor box for logos such as G-Sync Compatible or AMD FreeSync. These labels are usually printed clearly on certified products.

The user manual may also list supported adaptive sync technologies and required connection types.

Check Supported Connection Types

Adaptive sync support depends heavily on the type of connection used.

• DisplayPort: Required for most G-Sync and FreeSync features
• HDMI: Limited support depending on monitor and GPU generation

For NVIDIA GPUs, G-Sync Compatible generally works only via DisplayPort. Using HDMI may disable the feature.

Check Using NVIDIA Control Panel

If you are using an NVIDIA graphics card, you can check G-Sync support directly from the system.

• Right-click on the desktop and open NVIDIA Control Panel
• Select Display and click Set up G-Sync
• If your monitor supports G-Sync, the option will be available

If the option does not appear, the monitor may not support G-Sync or the connection is not compatible.

Check Using AMD Radeon Software

For AMD GPU users, FreeSync can be checked through AMD Radeon Software.

• Open AMD Radeon Software
• Go to the Display section
• Look for the AMD FreeSync status

If FreeSync is supported, it will show as Enabled or Supported.

Check Online Compatibility Lists

Both NVIDIA and AMD provide official compatibility lists.

• NVIDIA G-Sync Compatible monitors list on NVIDIA’s website
• AMD FreeSync monitor list on AMD’s website

If your monitor appears on these lists, compatibility is officially confirmed.

Test Adaptive Sync in Real Gameplay

The final step is testing the feature in real usage.

• Enable G-Sync or FreeSync in GPU settings
• Turn off V-Sync in the game settings
• Run a game with fluctuating frame rates

If screen tearing disappears and motion becomes smoother, adaptive sync is working correctly.

Common Reasons G-Sync or FreeSync Does Not Work

• Using an unsupported cable or port
• Outdated GPU drivers
• Adaptive sync disabled in monitor OSD settings
• GPU not compatible with the monitor

Always ensure drivers are updated and monitor settings are properly configured.

Conclusion

Checking whether a monitor supports G-Sync or FreeSync requires a combination of specification review, software verification, and real-world testing. By following the steps outlined above, users can accurately determine compatibility and ensure optimal gaming performance.

Adaptive sync technology plays a crucial role in delivering smooth and responsive visuals, making it an important feature for gamers and performance-focused users.
