Response Time

The Response Time test is a pursuit-camera style simulation that helps you visualize Gray-to-Gray (GtG) performance. It reveals how quickly your display’s pixels can transition between different colors and brightness levels.

🎛️ Test Controls & Options

🏎️ Pixel Speed (PPS): Adjust the speed using the slider from 100 to 3000 Pixels Per Second. Higher speeds make ghosting and smearing much more obvious.

📏 Width & Gap: Adjust the size of the moving bars to test how different surface areas affect your perception of motion.

🎨 Custom Colors: This is the most powerful part of the tool. • Obj L / Obj R: Change the colors of the moving bars. • Bg: Change the background color. 💡 Tip: Set Bg to Dark Gray and Obj to Light Gray to test “Dark Level Transitions”.

🔍 What to Look For

👻 Ghosting (Motion Blur): Do you see a faint, blurry “trail” left behind the bars? This indicates the pixels aren’t turning off fast enough.

✨ Inverse Ghosting (Overshoot): Do you see a bright or white “glow” trailing or leading the bars? This means your monitor’s Overdrive (Response Time) setting is too high, causing the pixels to “overshoot” their target color.

🖤 Black Smearing: Set the Background to Black and the Objects to a dark color. If you see a long, muddy trail, your panel (likely VA) has slow dark-level transitions.

🧠 Expert Interpretation

For a clean gaming experience, you want the bars to look as sharp as possible with no visible trails.

1. 🎮 Start with the default colors.
2. ✨ If you see “glowy” white trails, go to your monitor’s physical menu and lower the “Overdrive” or “Response Time” setting.
3. 👻 If you see long blurry trails, increase the “Overdrive” setting (but stop before you see overshoot).
