Response Time Test

Check your monitor or display for pixel response time, motion blur, and ghosting.

Response Time Test Patterns

Use these animated tests to evaluate your display's motion clarity and response time.

Moving Box Test

A white box moves across a black background. Look for trailing shadows (ghosting) or blur.

Ghosting Test

Rapidly flashing bars test your display's pixel transition speed. Look for afterimages.

Pursuit Camera Test

Follow the moving dot with your eyes. A slow response time will make the dot appear blurry.

UFO Motion Test

Classic motion test. The UFO should appear sharp without blur trails.

How to Test Response Time

  1. Native Refresh Rate: Ensure your monitor is running at its maximum refresh rate.
  2. Overdrive Settings: Test with different overdrive/response time settings if available.
  3. Moving Objects: Look for trailing shadows or ghost images behind moving objects.
  4. Eye Tracking: Follow moving objects with your eyes to detect motion blur.
  5. Compare: Compare different speed settings to see how your display handles motion.

Understanding Response Time

  • Response Time: The time it takes for a pixel to change from one color to another (typically measured in milliseconds).
  • Ghosting: Visible trail or shadow following moving objects, caused by slow pixel transitions.
  • Motion Blur: Blurring of moving objects, can be caused by both slow response time and sample-and-hold display technology.
  • Overdrive: Technology that speeds up pixel transitions, but too much can cause inverse ghosting (corona artifacts).
  • Good Response Time: Gaming monitors typically aim for 1ms (GtG), while 4-5ms is acceptable for general use.
