Refresh Rate Test
Detect your monitor's refresh rate, resolution, and aspect ratio. Get personalized gaming recommendations based on your display.
Click "Start Detection" to analyze your display
We'll measure your resolution, refresh rate, and aspect ratio
What We Detect
Comprehensive display analysis for optimal gaming
Resolution
Detect your current output resolution and identify if you're running HD, Full HD, 2K, or 4K.
Refresh Rate
Accurately measure your monitor's refresh rate using requestAnimationFrame (±1Hz precision).
Aspect Ratio
Identify your screen ratio (16:9, 21:9, 32:9) which affects FOV and target perception.
DPI Scaling
Check if Windows scaling is enabled (125%, 150%) which can affect gaming performance.
How to Use the Refresh Rate Test
Follow these simple steps to analyze your display and get personalized gaming recommendations.
Click Start Detection
Click the "Start Detection" button above. The tool will automatically begin analyzing your display.
Wait for Analysis
The tool measures 120 frames to accurately calculate your refresh rate. This takes about 1-2 seconds.
Review Results
View your display specs and personalized gaming recommendations based on your setup.
💡 Pro Tip
For the most accurate results, close other browser tabs and applications before running the test. Background processes can affect frame timing measurements.
Benefits & Optimization Tips
What you can do with your detection results
Resolution Optimization
- ✓2K/4K users: Lower your sensitivity by 10-20% compared to 1080p for the same "feel"
- ✓1080p users: Standard sensitivity ranges work well, focus on consistency
- ✓Competitive tip: Many pros use 1080p even on 4K monitors for larger targets
Refresh Rate Optimization
- ✓144Hz+: Enable G-Sync/FreeSync for tear-free gaming without input lag
- ✓240Hz+: You can use slightly higher sensitivity due to smoother tracking
- ✓60Hz users: Consider upgrading - 144Hz is the biggest jump in smoothness
Aspect Ratio Optimization
- ✓16:9: Standard competitive ratio, all games support it perfectly
- ✓21:9/32:9: Use 0% ADS multiplier to maintain consistency when scoping
- ✓4:3 stretched: Popular in CS2 - targets appear wider but move faster horizontally
DPI Scaling Optimization
- ✓100% scaling: Optimal for gaming - no input lag or rendering issues
- ✓125%+ scaling: Disable for games, or use per-app DPI settings in Windows
- ✓High DPI displays: Set game to run at native resolution with 100% scaling
🎮 Quick Action Checklist
Why Display Settings Matter for Gaming
Your monitor's specifications directly impact your gaming performance and how sensitivity "feels". Understanding these factors helps you optimize your settings for competitive play.
Resolution Impact
- • Higher resolution = smaller targets on screen
- • 4K requires more precise aiming than 1080p
- • Same sensitivity feels "faster" at higher res
- • Consider lower sensitivity for 2K/4K displays
Refresh Rate Impact
- • Higher Hz = smoother mouse tracking
- • 144Hz+ provides competitive advantage
- • Easier to track targets at high refresh rates
- • Can use slightly higher sensitivity with 240Hz+
Aspect Ratio Impact
- • 16:9 is standard for competitive gaming
- • 21:9 ultrawide gives wider FOV
- • 4:3 stretched makes targets appear wider
- • Affects horizontal vs vertical sensitivity feel
DPI Scaling Impact
- • 100% scaling is optimal for gaming
- • Higher scaling can cause input lag
- • May cause blurry visuals in some games
- • Disable for best competitive performance
Common Monitor Refresh Rates
What different refresh rates mean for gaming
Frequently Asked Questions
How accurate is the refresh rate detection?
Our detection uses requestAnimationFrame to measure actual frame intervals, achieving ±1Hz accuracy. This is the same method used by professional tools like TestUFO.
Why does my detected refresh rate differ from my monitor specs?
Your actual refresh rate depends on your Windows display settings, not just monitor capability. Check Display Settings → Advanced display settings to ensure you're running at your monitor's maximum Hz.
Should I disable Windows scaling for gaming?
Yes, for competitive gaming it's recommended to use 100% scaling. Higher scaling (125%, 150%) can introduce input lag and cause some games to render at non-native resolution.
Does higher refresh rate make a real difference?
Yes! Studies show that 144Hz provides noticeable improvement over 60Hz in reaction time and tracking accuracy. 240Hz offers further benefits, though with diminishing returns. Most esports pros use 240Hz or higher.
