Monitor Ghosting Test: Moving Object Trails
Runs locally in your browser. Nothing is uploaded.
Moving-object ghosting test
Track sharp moving patterns at three offsets and inspect the edge behind each target.
Take a pursuit-camera photo for documentation if needed. A normal phone photo without matching the target speed can add camera blur that is not panel ghosting.

Monitor ghosting test: This monitor ghosting test moves high-contrast targets across three lanes so you can track their trailing edges at different phases of the same motion.
How this monitor ghosting test works
Set the target speed, follow one object with your eyes, and compare the edge behind it on light and dark backgrounds. Pause the animation to confirm that any visible trail disappears when the target stops.
How to read the results
Ghosting is a same-color smear caused by slow pixel transitions. Overdrive overshoot, sometimes called inverse ghosting, appears as a bright or wrong-color halo because the voltage correction went too far. Camera motion blur and eye tracking can also change the apparent trail.
Common causes of failed tests
Motion trails depend on panel transition times, overdrive mode, refresh rate, temperature, dark-level behavior, frame pacing, and the specific color transition. More aggressive overdrive can reduce ordinary ghosting while increasing overshoot.
Troubleshooting before you replace hardware
Compare overdrive settings at the monitor’s actual refresh rate, retest after warm-up, disable motion-blur reduction for a baseline, and avoid judging from an unmatched handheld photo. Choose the least aggressive setting that controls trails without visible inverse halos.
For setup and buying context, see the screen test hub, color screens, dead pixel test, stuck pixel test, monitor ghosting test, FPS test, and refresh rate test.
Frequently asked questions
What is monitor ghosting?
It is a visible trail caused when pixels do not finish changing before the moving image advances.
What is inverse ghosting?
It is a bright or wrong-color halo caused by overdrive overshoot.
Can a phone photo prove ghosting?
Only a properly matched pursuit-camera method can separate panel trails from ordinary camera blur.
