Yep, very similar. It is extremely faint and looks similar to the faint sharp edges during 3D crosstalk. I have a similar effect on the VG278H too. Still allows an ASUS VG728HE to have more than 80% less motion blur, as I've written earlier from PixPerAn tests. Many, many times fainter trails than without LightBoost. I don't see any trailing effect at all on my BENQ XL2411T though. If that's all it is, I'd say don't bother switching from VG278HE to VG278H, especially if there's no purple tint in the afterimage like someone got.
