SCREEN 📌 Quick Summary: A response time test measures how quickly your monitor's pixels can change from one color to another. Faster response times (1ms) mean less ghosting and motion blur. Our free online tool tests this in under 60 seconds.
Response Time Test — Free & Online
Response time is one of the most important specs for gaming monitors. It determines how quickly pixels can transition, which directly affects motion clarity. Our response time test helps you evaluate your monitor's performance.
What Our Response Time Test Checks
- Pixel transition speed — How fast pixels change color
- Ghosting — Trails caused by slow transitions
- Motion blur — Blur caused by pixel lag
- Overdrive performance — How well your monitor handles fast motion
How to Run a Response Time Test
- Clean your screen — Remove dust and fingerprints.
- Set your monitor to maximum refresh rate — For accurate results.
- Click "Start Full Diagnosis" — The test runs in fullscreen mode.
- Watch the moving objects — Look for trails and blur.
Understanding Response Time
- 1ms (GtG) — Fastest, ideal for competitive gaming
- 2-4ms — Very good, minimal ghosting
- 5ms — Good, some ghosting may be visible
- 8ms+ — Slow, noticeable ghosting
How to Improve Response Time
- Adjust overdrive — Find the optimal setting in your OSD
- Increase refresh rate — Higher Hz reduces perceived response time
- Enable G-Sync/FreeSync — Reduces tearing and stuttering
- Upgrade to a faster panel — IPS or OLED for better response
