Adaptive sync technologies like G-SYNC and FreeSync eliminate screen tearing and stuttering during gaming. If you’ve invested in a monitor with these features, you need to enable them properly in Windows to see any benefit. This guide walks you through everything you need to know.
Quick Answer: Enabling G-SYNC or FreeSync
To turn on G-SYNC, open NVIDIA Control Panel, navigate to Display > Set up G-SYNC, check “Enable G-SYNC,” and select your monitor. For FreeSync, open AMD Radeon Settings, go to Display, and toggle “AMD FreeSync” on. You must also enable the feature in your monitor’s on-screen display menu.
Both require compatible hardware and proper connections to work correctly.
What You Need Before Starting
Before enabling adaptive sync, verify your system meets these requirements:
For G-SYNC
- NVIDIA graphics card (GTX 650 Ti Boost or newer for G-SYNC Compatible monitors)
- G-SYNC or G-SYNC Compatible certified monitor
- DisplayPort cable (required for most G-SYNC monitors)
- Latest NVIDIA graphics drivers
For FreeSync
- AMD graphics card (Radeon RX 200 series or newer)
- FreeSync compatible monitor
- DisplayPort or HDMI cable (check your monitor’s specifications)
- Latest AMD Radeon drivers
Important Cable Information
Your cable matters more than you might think:
| Technology | Recommended Cable | Why It Matters |
|---|---|---|
| G-SYNC | DisplayPort 1.2 or higher | G-SYNC modules require DisplayPort |
| G-SYNC Compatible | DisplayPort or HDMI 2.0+ | Depends on monitor specifications |
| FreeSync | DisplayPort or HDMI | Both work, but check monitor’s refresh rate limits per connection |
Using the wrong cable can prevent adaptive sync from working or limit your refresh rate.
How to Enable G-SYNC in Windows
Follow these steps carefully to activate G-SYNC on your system.
Step 1: Update Your Graphics Drivers
Download the latest drivers from the NVIDIA website. Outdated drivers cause most G-SYNC problems.
- Right-click on your desktop
- Select “NVIDIA Control Panel”
- Click “Help” in the menu bar
- Select “System Information”
- Check your driver version under “Driver Version”
If it’s more than two months old, update immediately.
Step 2: Open NVIDIA Control Panel
Two ways to access it:
- Right-click on your desktop and select “NVIDIA Control Panel”
- Open Windows Settings > search for “NVIDIA Control Panel”
If you don’t see the NVIDIA Control Panel option, your drivers aren’t installed correctly.
Step 3: Navigate to G-SYNC Settings
- In the left sidebar, find “Display”
- Click “Set up G-SYNC”
- You’ll see your compatible monitors listed
If your monitor doesn’t appear here, it’s either not connected properly or not G-SYNC compatible.
Step 4: Enable G-SYNC
- Check the box that says “Enable G-SYNC, G-SYNC Compatible”
- Choose between two options:
- “Enable for full screen mode” (recommended for maximum performance)
- “Enable for windowed and full screen mode” (better compatibility)
Full screen mode works best for most games and reduces input lag.
Step 5: Select Your Monitor
If you have multiple monitors:
- Click on your G-SYNC monitor in the list
- Make sure it’s highlighted
- Apply the settings
You can run G-SYNC on one monitor while using regular displays for others.
Step 6: Configure Additional Settings
Click “Apply” at the bottom right. Then:
- Stay in the NVIDIA Control Panel
- Go to “Change resolution” under Display
- Verify your monitor is set to its maximum refresh rate
- Confirm the resolution matches your monitor’s native resolution
Step 7: Enable G-SYNC in Monitor Settings
This step is critical and often forgotten:
- Press the physical buttons on your monitor
- Navigate to the display settings menu
- Find “G-SYNC,” “Variable Refresh Rate,” or “Adaptive Sync”
- Turn it ON
Every monitor has different menu systems. Check your monitor’s manual if you can’t locate this setting.
How to Enable FreeSync in Windows
AMD’s process differs slightly but remains straightforward.
Step 1: Update AMD Drivers
Visit the AMD driver download page and install the latest version for your graphics card.
- Right-click on your desktop
- Select “AMD Radeon Software”

- Look for your connected monitors
Step 4: Enable AMD FreeSync
- Find the “AMD FreeSync” toggle
- Switch it to “ON”
- If you have multiple monitors, select which one to enable it for
Some systems show “AMD FreeSync Premium” if your monitor supports the enhanced version.
Step 5: Adjust FreeSync Range (Optional)
Advanced users can modify the FreeSync range:
- In AMD Radeon Software, go to Display
- Find “Custom Resolutions” or “Display Specs”
- Note your monitor’s FreeSync range (example: 48-144Hz)
Don’t change these unless you understand what you’re doing.
Step 6: Enable FreeSync on Your Monitor
Just like G-SYNC, you must enable it on the monitor itself:
- Access your monitor’s OSD (on-screen display) menu
- Navigate to settings (often under “Gaming” or “Display”)
- Find “FreeSync,” “Adaptive Sync,” or “Variable Refresh Rate”
- Enable it
Some monitors automatically enable FreeSync when they detect an AMD GPU, but always verify manually.
Step 7: Verify Settings
Check that everything is configured:
- Ensure your refresh rate is set correctly in Windows Display Settings
- Confirm your resolution matches your monitor’s native resolution
- Restart your computer to finalize changes
Testing If G-SYNC or FreeSync Is Working
Enabling the feature doesn’t guarantee it’s functioning properly. Test it.
For G-SYNC Users
NVIDIA includes a built-in indicator:
- Open NVIDIA Control Panel
- Go to “Set up G-SYNC”
- Check “Enable G-SYNC Indicator”
- Launch a game
- Look for a small “G-SYNC ON” message on your screen
The indicator appears in the corner when G-SYNC is actively working.
For FreeSync Users
AMD’s method differs:
- Open AMD Radeon Software
- Enable the performance overlay (Ctrl+Shift+O by default)
- Launch a game
- Check if the FPS counter shows green (indicates FreeSync is active)
Testing With Online Tools
Visit specialized websites that demonstrate screen tearing:
- Blur Busters UFO Test (useful for both technologies)
- Windmill demo (shows stuttering and tearing clearly)
Move the UFO or windmill across the screen. With adaptive sync working, you’ll see smooth motion without tearing.
In-Game Testing
Play a demanding game:
- Choose a game that normally causes tearing
- Disable V-Sync in game settings
- Play for a few minutes
- Watch for screen tearing during fast motion
If you see no tearing even without V-Sync, your adaptive sync is working.
Common Problems and Solutions
Adaptive sync technologies sometimes fail to work properly. Here are fixes for typical issues.
G-SYNC Not Showing Up
Problem: Monitor doesn’t appear in G-SYNC settings
Solutions:
- Verify you’re using DisplayPort, not HDMI
- Check if your monitor is G-SYNC Compatible (not all monitors are)
- Update to the latest NVIDIA drivers
- Try a different DisplayPort cable
- Ensure your GPU supports G-SYNC (GTX 650 Ti Boost minimum)
FreeSync Greyed Out
Problem: Can’t toggle FreeSync on in AMD settings
Solutions:
- Update AMD drivers to the latest version
- Verify your monitor supports FreeSync (check manufacturer specs)
- Use DisplayPort or HDMI 2.0+ cable
- Enable FreeSync in your monitor’s menu first
- Check if your GPU supports FreeSync (RX 200 series minimum)
Monitor Says “Out of Range”
Problem: Screen goes black or shows “out of range” error
Solutions:
- Boot into Safe Mode
- Reset resolution to native settings
- Check refresh rate isn’t set too high for your cable
- Verify FreeSync/G-SYNC range matches your monitor’s capabilities
Flickering Screen With Adaptive Sync
Problem: Display flickers randomly during gaming
Solutions:
- Update monitor firmware (check manufacturer website)
- Adjust brightness (flickering often happens at low FPS near minimum range)
- Try enabling Low Framerate Compensation (LFC) if available
- Disable HDR temporarily to test if that’s causing issues
- Switch between windowed and fullscreen mode options
Performance Feels Worse
Problem: Games feel laggier with adaptive sync enabled
Solutions:
- Disable V-Sync in all games (adaptive sync replaces it)
- Check if frame rate is dropping below monitor’s minimum range
- Enable “Ultra Low Latency Mode” in NVIDIA settings
- Disable “Enhanced Sync” in AMD settings (conflicts with FreeSync)
- Verify game is running in fullscreen, not borderless windowed
Optimizing Your Adaptive Sync Experience
Getting adaptive sync working is just the start. Optimize it for best results.
Frame Rate Target
Set your frame rate cap wisely:
| Monitor Refresh Rate | Recommended FPS Cap | Why |
|---|---|---|
| 60Hz | 58 FPS | Prevents exceeding sync range |
| 144Hz | 141 FPS | Keeps you in adaptive sync range |
| 240Hz | 237 FPS | Maximum smoothness within range |
Staying just below your maximum refresh rate keeps adaptive sync active and minimizes input lag.
V-Sync Settings
The interaction between V-Sync and adaptive sync matters:
For G-SYNC:
- Enable V-Sync in NVIDIA Control Panel
- Disable V-Sync in individual games
- This acts as a frame rate limiter when you exceed your monitor’s range
For FreeSync:
- Disable V-Sync everywhere
- Use AMD’s Radeon Chill or frame rate limiters instead
- FreeSync works best without V-Sync interference
In-Game Settings
Configure your games properly:
- Turn OFF V-Sync in every game
- Disable “Triple Buffering” if present
- Use exclusive fullscreen mode (not borderless window)
- Enable any in-game frame rate limiters to stay within your monitor’s range
- Disable “Fast Sync” or “Enhanced Sync” features
Refresh Rate Configuration
Ensure Windows is set correctly:
- Right-click desktop
- Select “Display settings”
- Scroll down to “Advanced display settings”
- Choose your monitor
- Select highest available refresh rate from dropdown
- Apply changes
Many users accidentally run their 144Hz monitor at 60Hz because Windows doesn’t automatically select the maximum rate.
G-SYNC vs FreeSync Differences
While both technologies achieve similar results, they work differently.
Technical Differences
G-SYNC:
- Uses proprietary NVIDIA hardware module in monitor
- Tighter quality control and certification
- Generally wider variable refresh rate ranges
- Typically more expensive monitors
- Works only with NVIDIA GPUs
G-SYNC Compatible:
- No proprietary hardware required
- NVIDIA tested and approved certain FreeSync monitors
- Works like FreeSync but certified by NVIDIA
- More affordable than full G-SYNC
FreeSync:
- Open standard using VESA Adaptive-Sync

Frequently Asked Questions
Can I use FreeSync with an NVIDIA card?
Yes, newer NVIDIA GPUs (GTX 10-series and later) support FreeSync monitors through “G-SYNC Compatible” mode. Enable it in NVIDIA Control Panel under G-SYNC settings. Not all FreeSync monitors work perfectly with NVIDIA cards, but most function adequately.
Do I need to keep V-Sync enabled with G-SYNC or FreeSync?
For G-SYNC, enable V-Sync in NVIDIA Control Panel but disable it in games. This prevents tearing when exceeding your monitor’s maximum refresh rate. For FreeSync, disable V-Sync everywhere and use frame rate limiters instead to stay within your monitor’s range.
Why does my screen flicker with adaptive sync enabled?
Flickering usually occurs when frame rates drop near the minimum of your monitor’s adaptive sync range. Update your monitor’s firmware, increase graphics settings to maintain higher frame rates, or adjust brightness settings. Some monitors flicker more than others due to panel quality.
Can I use G-SYNC or FreeSync with borderless windowed mode?
G-SYNC supports windowed mode if you enable “Enable for windowed and full screen mode” in NVIDIA Control Panel. FreeSync primarily works in exclusive fullscreen mode, though some games support it in borderless window. Fullscreen mode always provides better performance with less input lag.
Does adaptive sync increase input lag?
No, adaptive sync actually reduces input lag compared to traditional V-Sync. G-SYNC and FreeSync add less than 1ms of delay, while traditional V-Sync can add 15-30ms. Enable “Ultra Low
