Actually, pixel persistence is no longer the main cause of motion blur, because it's only 2ms out of a refresh (16.7ms at 60Hz, or 8.3ms at 120Hz).
Most motion blur on a modern LCD monitor is caused by the sample-and-hold nature of the monitor. Your eyes are continuously moving, while tracking moving objects, so the refresh is blurred across your eyes (see
Science & References, scroll down for the academic papers that explains the difference between pixel persistence motion blur, and eye-tracking-based motion blur).
Strobing the backlight (once per refresh), eliminates the motion blur, and makes it flicker like a CRT, but at 120Hz, the flicker isn't annoying (like 60Hz CRT). If you already own a BENQ XL2411T, it also uses LightBoost. You can also force-enable LightBoost (strobe backlight) on a monitor even when not playing 3D (e.g. BENQ XL2411T) in order to to get zero motion blur -- completely eliminates motion blur on BENQ XL2411T.
There's some great testimonials for the zero motion blur effect when you enable the LightBoost strobe backlight on the BENQ XL2411T, a popular monitor from overclockers.uk online store.

Confirmed!! I've since purchased the Asus VG278H & a GTX680, and it works! Zero motion blur confirmed --
looks like CRT motion.

Then yesterday I, for some reason, disabled the 3d and noticed there was no ghosting to be spotted at all in titan quest.
It's like playing on my old CRT.

I can
confirm this works on BENQ XL2420TX
EDIT: And OMG i can play scout so much better now in TF2, this is borderline cheating.

Thanks for this, it really works! Just tried it on my VG278H.
Its like a CRT now!

Oh my, I just got Skyrim AFK camera spinning (which I used to test LCD's versus the [Sony CRT] FW900) to run without stutters and VSYNC locked to 120.
This Benq with Lightboost is just as crystal clear if not clearer than the FW900 motion. I am in awe. More testing tomorrow. Any of my doubts about this Lightboost technology have been vaporized! I've been playing around with this fluid motion on this monitor for like 6-hours straight, that is how impressive it is.
