Ghosting test
Watch a moving edge against contrasting backgrounds and observe any trail or smear yourself.
Watch a moving edge
Look for a trail or black smearing around the moving block on your own display. Change the motion speed and viewing distance to compare what you see.
Some display-test searches call a moving-object pattern a “UFO test”. This is an original moving-edge visual prompt, not a standardized motion benchmark.
This is a visual browser animation, not a panel response-time, overshoot, or motion-blur measurement. The pattern does not flash.
Watch the block as it changes direction. Select slow, medium, and fast motion, then pause it to compare the moving edge with a still image. Keep your viewing distance and display settings consistent.
You can open the pattern on a laptop or TV browser. If a connected or cast device processes the image, its settings can change how motion appears, so treat the result as a visual prompt only.
What a motion trail can and cannot show
Perceived motion trails also depend on the displayed content, refresh rate, overdrive settings, and your viewing conditions. This original browser animation is a visual prompt, not a standardized ghosting benchmark or a response-time measurement.
Can a monitor ghosting test fix the trail?
No. An online ghosting or anti-ghosting test cannot change the monitor’s overdrive setting or guarantee a fix. If you inspect the monitor menu, change one supported response-time setting at a time and compare it during normal motion; extreme overdrive can create a different visible artifact.
For browser frame cadence, see the refresh rate test. For refresh rate selected by the operating system, check its display settings and your monitor’s menu.
