Screen tearing, that horizontal split where the top and bottom halves of your image show different frames, is one of the most distracting artifacts in PC gaming. Variable refresh rate technology fixes it by syncing your monitor’s refresh to your GPU’s frame output, giving you tear-free, smooth motion without the input-lag penalty of old-fashioned V-Sync. In 2026, nearly every gaming monitor supports it, but enabling it correctly takes a couple of deliberate steps.
This guide walks through turning on G-Sync or FreeSync from the monitor menu to the GPU control panel to the in-game settings, plus how to confirm it is actually working. Get all three layers aligned and you unlock the buttery-smooth experience your high-refresh panel was built to deliver.

Watch: How to Enable G-Sync or FreeSync — Video Review
Confirm Your Monitor and Cable Support VRR
Start by verifying your hardware. Most gaming displays, from the Samsung Odyssey OLED G5 to the ASUS TUF Gaming VG259QM5A, advertise FreeSync, G-Sync Compatible, or both. The connection matters too: for the full variable-refresh range, use DisplayPort rather than HDMI on desktop GPUs, and make sure the cable is up to spec. A VESA-certified DisplayPort 1.4 cable like the Capshi 8K DP cord guarantees the bandwidth needed for high refresh rates at higher resolutions without dropouts.
- Check your monitor’s spec sheet for FreeSync or G-Sync Compatible support.
- Use a certified DisplayPort cable for the widest VRR range on desktop.
- Note your panel’s supported refresh window, for example 48 to 240Hz.
Enable VRR in the Monitor’s On-Screen Menu
Variable refresh must be switched on at the display itself first. Open your monitor’s on-screen display using its physical buttons or joystick, find the gaming or performance section, and enable Adaptive-Sync, FreeSync, or G-Sync depending on how your model labels it. Some monitors offer FreeSync Premium or a similar tier with low-framerate compensation, enable the highest tier your panel supports. Without this step, the GPU has nothing to sync to.
Turn It On in Your GPU Control Panel
Next, enable the matching setting in your graphics driver. On NVIDIA cards, open the NVIDIA app or Control Panel, go to the G-Sync section, and enable G-Sync for both fullscreen and windowed modes, then select your monitor if you run more than one. On AMD cards, open the Adrenalin software, find AMD FreeSync, and toggle it on for your display. This is the layer people most often forget, and its absence is why VRR sometimes appears not to work even on a capable monitor.
Set In-Game Options and Cap Your Frame Rate
For the best results, leave in-game V-Sync off or set to the GPU-controlled option, and cap your frame rate a few frames below your monitor’s maximum refresh, for example 141 fps on a 144Hz panel. Staying just inside the VRR window keeps every frame synced and tear-free; letting frame rate exceed the refresh ceiling reintroduces tearing. Many players enable a global frame cap in the driver to enforce this across all games.
Tips
- Use DisplayPort over HDMI on desktop: it typically offers the widest, most reliable variable-refresh range.
- Cap FPS just below max refresh: a cap a few frames under your panel’s ceiling keeps you inside the tear-free VRR window.
- Enable the highest FreeSync tier: Premium and Premium Pro add low-framerate compensation for smoothness even when FPS dips.
- Verify with a test pattern: use a VRR test or the monitor’s refresh-rate overlay to confirm the number changes with your frame rate.
Frequently Asked Questions
Can I use G-Sync on a FreeSync monitor?
Often yes. Many FreeSync monitors are certified as G-Sync Compatible, meaning an NVIDIA GPU can enable G-Sync over DisplayPort on them. Even uncertified FreeSync displays frequently work; you can enable G-Sync manually in the NVIDIA settings and test for tearing or flicker.
Should I use V-Sync with G-Sync or FreeSync?
Keep in-game V-Sync off and instead cap your frame rate below the monitor’s maximum. Some enthusiasts enable driver-level V-Sync as a safety net for frames that momentarily exceed the refresh ceiling, but the frame cap is the more important setting for staying in the tear-free range.
Why is my variable refresh rate not working?
The most common cause is skipping the GPU control panel step, VRR must be enabled at the monitor and in the driver. Other culprits include using an HDMI cable that limits the range, running the game in a windowed mode without VRR support, or a frame rate outside the monitor’s supported window.
Does G-Sync or FreeSync add input lag?
No, that is the whole advantage over traditional V-Sync. Variable refresh eliminates tearing by matching the display to the GPU rather than forcing the GPU to wait, so it delivers smooth motion with negligible added latency, ideal for both immersive and competitive play.
Conclusion
Enabling G-Sync or FreeSync is a three-layer job: switch it on at the monitor, enable the matching setting in your GPU control panel, and cap your frame rate just under your refresh ceiling. Use a certified DisplayPort cable to guarantee the bandwidth, confirm it is active with a quick test, and you will banish screen tearing for good, finally seeing the smooth, responsive gameplay your high-refresh monitor was designed to provide.
