Response Time Test & Ghosting Test
This ghosting test helps you visually assess your monitor's response time. Observe the fast-moving squares below to check for motion blur.
How to Use the Response Time Test
Monitor response time is how quickly a pixel can change colors. A slow response time causes motion blur, commonly known as ghosting, where a faint trail is visible behind moving objects. This online response time test makes it easy to see these artifacts.
- Good Response Time: The moving square will have sharp, clean edges with little to no visible ghosting or trail.
- Poor Response Time (Ghosting): You will see a blurry or smeared trail following the moving square. Our ghosting test makes this effect obvious, especially on slower VA or IPS panels.
- Overdrive Artifacts (Inverse Ghosting): If you see a bright or differently colored trail ahead of the object, your monitor's overdrive setting might be too aggressive. This is also a key part of any thorough response time test.
Response Time Test FAQ
What is monitor ghosting?
Monitor ghosting is a visual artifact where a trail or "ghost" of a moving object remains on screen. It is caused by a slow pixel response time, meaning the pixels cannot change color fast enough to keep up with the image. Our ghosting test is specifically designed to make this effect easy to spot.
How do I fix ghosting on my monitor?
You can often reduce ghosting by adjusting your monitor's "Overdrive" or "Response Time" setting in its on-screen menu. Setting it to 'Fast' or 'Medium' is often a good balance. If set too high, it can cause "inverse ghosting." Running this response time test while adjusting the settings is the best way to find the optimal balance.
