Follow a moving target to compare visible trailing, smearing and response behavior across display modes and refresh settings.
Why this test is useful
Look for trailing copies, smearing or colored edges behind the moving target. Compare one display setting at a time because response time and overdrive interact. When comparing monitor modes, change one setting at a time and use the same test speed, brightness and viewing position.
Before you start
- If the computer is under heavy load, close demanding apps before judging timing or motion so browser scheduling is less likely to distort the result.
- Start at the brightness you normally use. Extreme brightness can exaggerate some panel behavior and make the result less representative of daily use.
- When comparing monitor modes, change one setting at a time and use the same test speed, brightness and viewing position.
A reliable way to run the test
- Look for trailing copies, smearing or colored edges behind the moving target. Compare one display setting at a time because response time and overdrive interact.
- When comparing monitor modes, change one setting at a time and use the same test speed, brightness and viewing position.
- A browser refresh estimate should settle near a stable value. Variable refresh rate, power saving and scheduler jitter can cause small changes between samples.
- Long exposure phone photos can create trails that are not identical to what your eyes see, so use photographs carefully when judging ghosting.

What to do next
- When comparing monitor modes, change one setting at a time and use the same test speed, brightness and viewing position.
- A browser refresh estimate should settle near a stable value. Variable refresh rate, power saving and scheduler jitter can cause small changes between samples.
- After an artificial pattern reveals something, check the same area with real photos, video or games at your normal viewing distance.
What this test cannot prove
Long exposure phone photos can create trails that are not identical to what your eyes see, so use photographs carefully when judging ghosting. Do not make a hardware decision from one pattern alone. Repeat the observation with a second pattern or related test. Browser timing and display information are practical estimates, not laboratory instruments or certified specifications.
