Understand GtG and MPRT response times and how they affect motion clarity and ghosting
| Panel Type | Typical GtG | MPRT | Ghosting | Best For |
|---|---|---|---|---|
| OLED | 0.1-0.5 ms | Excellent | None | Premium Gaming, Movies |
| TN | 1-2 ms | Good | Minimal | Competitive Gaming |
| IPS | 4-8 ms | Moderate | Some | General Use, Color Work |
| VA | 4-20 ms | Variable | Noticeable | Contrast, Movies |
Enter GtG Response Time
Input your display’s Gray-to-Gray response time in milliseconds. You can find this in your monitor’s specifications. Typical values: OLED: 0.1-0.5ms, TN: 1-2ms, IPS: 4-8ms, VA: 4-20ms. Be aware that advertised specs are often best-case scenarios.
Select Refresh Rate
Choose your display’s refresh rate. Higher refresh rates like 144Hz or 240Hz have shorter frame times, making GtG response time more critical. At 60Hz, frame time is 16.67ms; at 144Hz, it’s only 6.94ms.
Choose Panel Type
Select your display’s panel technology. This affects the expected response time characteristics. OLED panels have near-instant pixel response. TN panels are fastest among LCDs. IPS offers best colors, and VA has best contrast but slowest response.
Motion Blur Reduction (Optional)
If your monitor has BFI (Black Frame Insertion) or similar technology, enable this option. Motion blur reduction strobes the backlight to reduce perceived blur, significantly improving MPRT at the cost of brightness and potential flicker sensitivity.
Analyze the Results
Compare your GtG response time to the frame time. Ideally, GtG should be less than frame time. Check the ghosting risk rating and MPRT value. The motion blur visualization shows how your display compares to fast and slow panels.
Pro Tip: Don’t rely solely on advertised GtG specs. Many manufacturers measure at optimal overdrive settings that can cause inverse ghosting (overshoot). Look for independent reviews that test real-world response times across the full gray-to-gray range.
GtG vs MPRT
GtG (Gray-to-Gray) measures pixel transition speed. MPRT (Moving Picture Response Time) measures perceived motion blur, which also depends on refresh rate.
Why It Matters
Slow response time causes ghosting – trailing shadows behind moving objects. Fast-paced games and sports benefit most from low response times.
Marketing vs Reality
Advertised 1ms GtG often uses aggressive overdrive causing inverse ghosting. Real-world performance is typically 2-5ms for most panels.
Refresh Rate Relationship
Higher refresh rates require faster response times. At 144Hz, frame time is 6.94ms – GtG should ideally be lower than this.
