Refresh Rate Test
This test helps you verify your monitor's refresh rate and detect motion blur or ghosting issues.
• UFO Test: Watch the green blocks move. Smoother = higher refresh rate
• Response Time: Flickering checkerboard tests pixel transitions
• Persistence: Moving line shows ghosting/trailing
• FPS Counter: Shows your actual frame rate
Tips:
• Ensure your monitor is set to its highest refresh rate in display settings
• Disable V-Sync in browser for accurate results
• Full screen mode works best
