Understanding Refresh Rate Technology & Performance Metrics
Refresh Rate vs Reality
Advertised refresh rates don't tell the whole story:
- Frame skipping: Monitor drops frames to maintain timing (31% of monitors)
- Overdrive artifacts: Aggressive response time causes overshoot (24% of cases)
- Variable performance: Refresh rate varies with content (18% of displays)
- Connection bottlenecks: Cable/port limitations reduce effective rate (27% of setups)
Motion Clarity Science
Three factors determine motion clarity:
- Refresh rate: How often the image updates (Hz)
- Response time: How fast pixels change (ms)
- Persistence time: How long pixels stay lit (sample-and-hold effect)
- Motion processing: Black frame insertion, strobing, MPRT optimization

How Our Professional Refresh Rate Test Works
Advanced Motion Analysis Engine
Our refresh rate test uses high-precision timing analysis and visual pattern recognition to measure real-world performance:
1. Frame Rate Verification
Measures actual frame delivery using JavaScript performance timing APIs with sub-millisecond precision.
2. Frame Skipping Detection
Identifies dropped or duplicated frames using sequential frame numbering and timing analysis.
3. Motion Clarity Assessment
Tests moving patterns at various speeds to measure motion blur and persistence effects.
4. Adaptive Sync Testing
Evaluates variable refresh rate performance across different frame rate ranges.

Motion Blur vs Response Time: The Complete Relationship
Understanding Motion Perception
Sample-and-Hold Effect
LCD monitors hold each frame static until the next refresh, creating perceived motion blur even with instant pixel response times.
Example: At 60Hz, a 1000px/s object appears blurred across 16.7 pixels
Response Time Impact
| Response Time | 60Hz Motion Blur | 144Hz Motion Blur | 240Hz Motion Blur |
|---|---|---|---|
| 1ms (ideal) | 16.7px @ 1000px/s | 6.9px @ 1000px/s | 4.2px @ 1000px/s |
| 5ms (typical) | 21.7px @ 1000px/s | 11.9px @ 1000px/s | 9.2px @ 1000px/s |
| 10ms (slow) | 26.7px @ 1000px/s | 16.9px @ 1000px/s | 14.2px @ 1000px/s |
Motion Blur Reduction Technologies
Black Frame Insertion (BFI)
How it works: Inserts black frames between content frames
Benefits: Reduces motion blur by 60-80%
Drawbacks: 50% brightness reduction, 120Hz+ required
Backlight Strobing
How it works: Pulses backlight synchronized with refresh
Benefits: CRT-like motion clarity
Drawbacks: Brightness loss, potential flicker sensitivity
Motion Clarity Recommendations by Use Case
Competitive FPS:
240Hz + BFI/Strobing
1ms response time
Racing Games:
144Hz + motion blur reduction
Low input lag priority
General Gaming:
144Hz standard
5ms response acceptable
Overdrive Artifacts & Settings Optimization
Understanding Overdrive Technology
How Overdrive Works
Overdrive applies extra voltage to LCD crystals to speed up pixel transitions, reducing response times from 16ms to 1-5ms.
However, excessive overdrive causes visible artifacts that can be worse than slow response times.
Common Overdrive Artifacts
- Overshoot: Pixels briefly go beyond target value (coronas, halos)
- Undershoot: Pixels don't reach target value quickly enough
- Oscillation: Pixels bounce between values before settling
- Inverse ghosting: Bright trails following moving objects
Overdrive Optimization Guide
Too Low (Off/Slow)
Symptoms: Ghosting, smearing
Best for: Static content, office work
Optimal (Medium/Normal)
Symptoms: Clean motion, minimal artifacts
Best for: Gaming, mixed content
Too High (Fast/Extreme)
Symptoms: Inverse ghosting, coronas
Best for: Rarely optimal
Brand-Specific Overdrive Recommendations
| Brand | Setting Name | Recommended | Notes |
|---|---|---|---|
| ASUS | Trace Free | 60-80 | Model-dependent, test with our tool |
| Acer | Overdrive | Normal | Extreme causes artifacts on most models |
| BenQ | AMA | High | Premium setting usually optimal |
| LG | Response Time | Fast | Faster setting often causes overshoot |
| Samsung | Response Time | Standard | Fast/Fastest usually too aggressive |

Common Adaptive Sync Issues & Solutions
Flickering at Low Frame Rates
Cause: VRR range doesn't extend low enough, LFC not working
Solution: Enable Low Framerate Compensation (LFC) or set minimum FPS limit
Stuttering at High Frame Rates
Cause: Frame rate exceeds VRR maximum, reverts to fixed refresh
Solution: Cap frame rate 3-5 FPS below maximum VRR rate
Input Lag Increase
Cause: VRR processing overhead, frame timing changes
Solution: Disable VRR for competitive gaming or use fixed refresh rate
