Ghosting Test - Check Motion Trails and Inverse Ghosting
Run a free browser ghosting test to check motion trails, dark smears, blur and bright inverse ghosting. Compare speeds, backgrounds and monitor settings.
Quick answer
A ghosting test uses moving shapes to visually check motion trails, blur, overshoot and display response behavior.
Method: ScreenTestKit generates the test surface in your browser. Results depend on visual inspection; the site does not read or diagnose physical panel hardware.
How to use this test
- Open the moving test on the screen you want to check.
- Use the speed and background that make trails easiest to see.
- Compare monitor overdrive or response-time settings if your display offers them.
- Run the refresh rate test afterward to confirm the expected display mode.
What to watch for
- Dark or light trails that follow moving objects.
- Bright inverse trails caused by too much overdrive.
- Blur that changes when refresh rate, response mode or brightness changes.
- Motion problems that are visible in games, scrolling text or video.
How to interpret results
Soft trail
This can be normal pixel response behavior, especially on slower panels.
Bright inverse trail
Lower the monitor overdrive setting if available, because strong overdrive can create overshoot.
Motion plus low FPS
Check refresh rate and frame time before blaming the panel itself.
Frequently asked questions
Can a browser ghosting test replace lab equipment?
No. It is a practical visual comparison tool, not a measured response-time instrument.
Why does ghosting change with settings?
Refresh rate, response time mode, overdrive, brightness and panel type all affect perceived trails.
