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.
動画応答速度 (MPRT)
動画応答時間 (MPRT)は、ピクセルが画面上で見える時間を測定します。GtGが速くてもMPRTが高いとモーションブラーが発生します。黒挿入 (BFI) などの技術はMPRTを下げ、CRTのような鮮明さを作り出します。
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.
