Test your monitor's pixel response time and detect ghosting, motion blur, and overshoot issues. Essential for gaming monitor evaluation.
Observe the moving white box. Ghosting or trailing indicates slower response times:
These rotating patterns help identify ghosting and inverse ghosting (overshoot):
Response time measures how quickly pixels change color. Lower is better for gaming. Standard IPS panels: 4-5ms, TN panels: 1ms, OLED: <0.1ms.
Trail behind moving objects caused by slow pixel transitions. Look for faint copies of the moving box in the test above.
Monitor overdrive reduces ghosting but can cause inverse ghosting (coronas). Test different overdrive levels in your monitor OSD.
| Response Time | Rating | Best For |
|---|---|---|
| < 2ms | Excellent | Competitive gaming |
| 2-4ms | Very Good | Gaming, general use |
| 4-8ms | Good | Casual gaming, work |
| 8-16ms | Average | Office work, media |
| > 16ms | Poor | Not recommended for gaming |
