Yeah, I have no flickering. Active is better. My Asus not only has 120 Hz, it has a Stroboscop as alternative backlightning which results in zero Motion Blur. Like an old CRT Monitor. Also, by Mod I can force this for 2D also.

But strange is, after 3 Month of using a 3D MOnitor, I´m so used to it already, I recognize the Effect as normal.

Having 5 good Surround Speakers in my Opinion is even better.
