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.
Persistance du mouvement (MPRT)
Le Moving Picture Response Time (MPRT) mesure la durée pendant laquelle un pixel reste visible à l'écran. Un MPRT élevé provoque un flou de mouvement même si GtG est rapide. Des techniques telles que le Backlight Strobing (BFI) réduisent le MPRT pour créer une clarté semblable à celle d'un CRT.
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.
