Ghosting Test

Ghosting is the faint trail or shadow that follows a moving object across the screen. It happens when pixels change color too slowly, leaving a smear behind fast motion in shooters, racing games and sports. The opposite problem, inverse ghosting or overshoot, shows a bright halo around moving edges when a monitor pushes pixels too hard.

How To Run A Ghosting Test

Watch an object moving across the screen at a steady speed and follow it with your eyes. A clean edge means fast pixel response. A dark trail means ghosting, while a bright or colored outline means overshoot. Try different speeds and frame rates, since ghosting often gets worse at lower refresh rates or in dark scenes on VA panels.

How To Reduce Ghosting

• Set the overdrive or response time option to the middle level.
• Use the highest refresh rate the screen supports.
• Turn off motion smoothing and heavy processing on TVs.
• Use Game mode for lower processing and faster response.

Which App The Install Button Opens

No Android app uses this exact name, so the button opens a related app, Refresh Rate Checker on Google Play. Its moving object test at multiple frame rates lets you watch for trails and smearing. For timing in milliseconds, read our Response Time Test page.
