Understanding Motion Blur & Ghosting
What is Ghosting?
Ghosting is a visual artifact where a moving object leaves a trail of fading copies behind it. This happens when your monitor's pixels can't change color fast enough to keep up with the moving image. It's common on VA panels and older IPS screens.
Response Time (GtG)
Gray-to-Gray (GtG) measures how long it takes a pixel to change from one shade of gray to another. A lower number (e.g., 1ms) is better. If the response time is slower than the refresh rate window, you get blur.
动画响应时间 (MPRT)
动画响应时间 (MPRT) 测量像素在屏幕上保持可见的时间。即使 GtG 很快，高 MPRT 也会导致运动模糊。诸如 背光插帧 (BFI) 之类的技术可以降低 MPRT，从而创造出类似 CRT 的清晰度。
How to Interpret This Test
Sharp Image: If you can clearly see the details of the moving UFO/text, your monitor has excellent motion clarity.
Blurry Trail: A long trail behind the object indicates slow pixel response times.
Inverse Ghosting (Corona): If you see a bright/white halo around the moving object, your monitor's "Overdrive" setting is too high. Try lowering it in your monitor's OSD menu.
