Key takeaways
- First turn on the FreeSync or G-Sync option in your monitor’s on-screen display menu.
- Open the NVIDIA Control Panel and go to “Set up G-SYNC.”
- Check “Enable G-SYNC, G-SYNC Compatible” and choose whether to apply it in fullscreen or also windowed mode.
- Confirm your monitor is selected and apply; the setting persists across reboots.
What's inside
If your games show a horizontal line where the top and bottom of the image seem misaligned during fast motion, you are seeing screen tearing, and adaptive sync is the cure. G-Sync and FreeSync are technologies that synchronize your monitor’s refresh rate to your GPU’s frame output in real time, eliminating tearing without the input lag penalty of old-school V-Sync. The result is buttery-smooth motion that makes even mid-range hardware feel more premium.
The best part is that most gaming monitors sold today support adaptive sync, and it is often just sitting there switched off. Enabling it takes a couple of minutes in your GPU control panel and your monitor’s on-screen menu. This guide explains how G-Sync and FreeSync work, walks through enabling them for both NVIDIA and AMD systems, and covers the settings that make the experience flawless in 2026.

Watch: How to Enable G-Sync or FreeSync — Video Review
Understand Adaptive Sync
Traditionally your monitor refreshes at a fixed rate, say 144 times per second, regardless of how many frames your GPU produces. When those two fall out of step, you get tearing or, with V-Sync, added latency and stutter. Adaptive sync flips the relationship: the monitor waits for the GPU and refreshes exactly when a new frame is ready. FreeSync is AMD’s open implementation and G-Sync is NVIDIA’s, and today most G-Sync Compatible monitors work with both GPU brands over DisplayPort.
Enable It on NVIDIA
- First turn on the FreeSync or G-Sync option in your monitor’s on-screen display menu.
- Open the NVIDIA Control Panel and go to “Set up G-SYNC.”
- Check “Enable G-SYNC, G-SYNC Compatible” and choose whether to apply it in fullscreen or also windowed mode.
- Confirm your monitor is selected and apply; the setting persists across reboots.
Enable It on AMD
On a Radeon system, again start by enabling FreeSync in the monitor’s OSD menu. Then open the AMD software, go to the display settings, and toggle AMD FreeSync on for your monitor. That is it, tearing-free gaming is now active. For both brands, use a certified DisplayPort cable for the most reliable high-refresh adaptive sync, since some cheap or damaged cables fail to negotiate the feature correctly.
Dial In the Best Settings
Adaptive sync works within your monitor’s supported range, so to stay inside it, cap your frame rate a few frames below your monitor’s maximum refresh; on a 144Hz panel, a cap around 138 to 141fps keeps you in the sync window and minimizes latency. Leave in-game V-Sync off when using adaptive sync, or configure the specific low-lag combination your setup supports. Once set, you should never see a tear again while enjoying the lowest possible input lag.
Tips
- Always enable the sync option in the monitor’s own menu first; the GPU setting alone is not enough on many displays.
- Cap your frame rate just below the monitor’s max refresh to stay within the adaptive sync range.
- Use a VESA-certified DisplayPort cable for reliable high-refresh adaptive sync connections.
- If you see flicker in certain scenes, update your GPU driver and monitor firmware, which often resolves it.
Frequently Asked Questions
Can I use FreeSync with an NVIDIA GPU?
Yes, in most cases. NVIDIA supports “G-SYNC Compatible” mode over DisplayPort, which works with the majority of FreeSync monitors. Enable FreeSync in the monitor menu and G-SYNC Compatible in the NVIDIA Control Panel to use it.
Does adaptive sync add input lag?
No, unlike traditional V-Sync, adaptive sync eliminates tearing without the significant latency penalty. When you cap your frame rate just below the refresh ceiling, you get tear-free motion at close to the lowest possible input lag.
Do I need a special monitor?
You need a monitor that supports FreeSync or G-Sync, but the vast majority of gaming monitors sold today do. Check your monitor’s specs or on-screen menu for a FreeSync or adaptive sync option; if it is there, you can enable it.
Should I cap my frame rate?
Yes. Capping a few frames below your monitor’s maximum refresh keeps your frame rate inside the adaptive sync range, where the technology works, and avoids falling back to tearing or added latency at the ceiling. It is the key setting for a perfect experience.
Conclusion
G-Sync and FreeSync are free performance-feel upgrades hiding in almost every modern gaming monitor. Enable the sync option in your display’s menu, turn on G-SYNC Compatible or FreeSync in your GPU software, use a good DisplayPort cable, and cap your frame rate just below your refresh ceiling. Do that and screen tearing vanishes, replaced by smooth, low-latency motion that makes every game look and feel better.
