Quote:On *certain* monitors, the LightBoost double image effect shows up easily with 120fps@120Hz VSYNC ON animations; during high-contrast situations, such as PixPerAn (downloadable), or Blur Busters Motion Tests (coming soon). Some people are very sensitive to this, while others are not.
Pre-requisites to see the double-ghost:
(1) Perfect animations (120fps@120Hz VSYNC)
(2) High contrast edge (bright/dark)
(3) High speed movement
Basically, it's roughly the same intensity as 3D crosstalk.
Fainter 3D crosstalk = Fainter 2D doubleghost in LightBoost.
That said, other image quality aspects (e.g. color) of the XL2720T may be better, but the LightBoost faint-sharp-trailing-ghost effect is nearly nonexistent on XL2411T's and VG248QE's, while worse on XL2420T's and VG278HE's. The VG278H (non 'E') is roughly somewhere in between a VG248QE and the VG278HE.
It depends on what attributes you are most sensitive to. Both of you may be right for different reasons.
I will be taking pursuit camera photographs of the LightBoost double-ghost effect, which amplifies itself if I raise my contrast to 90 on my VG278H, instead of 65-75 that I typically run it at, to eliminate it.
