I'm interested in this as well.

Will the G series include "BenQ's motion blur reduction" or only ULMB?
I don't like how ULMB is limited to 120Hz Where BenQ's motion blur reduction can strobe at 144Hz.

People who would like to be able to adjust persistence (0.5ms persistence to 3ms) will be very interested in this utility coming soon. This is a much wider adjustment range than LightBoost 10% versus 100% -- it's like getting LightBoost less than 10%, and LightBoost above 100%. This utility, however, will only work on newer shipments of BENQ Z-Series (not yet shipping, but almost).
Is 25cd/m2 light, viewable in a normally lighted room? How do I know that I buy the right xl2420z, compatible with your utility? Thanks

Depends on whether you prefer brighter or dim monitors. No current-selling monitor of 1ms persistence (on LightBoost=10%, or on new XL2720Z firmware adjusted) are viewable in a normally lighted room by people who prefer bright monitors.

As a rule of thumb, the higher the persistence of a strobe backlight (longer strobe flash), the brighter the monitor is. It's a motion blur versus brightness tradeoff. This occurs with nearly all strobe backlight monitors. BENQ Blur Reduction is no different from this persistence-versus-brightness tradeoff.

I presume you're already familiar with the brightness tradeoffs of LightBoost=10% on existing LightBoost monitors? If you have seen LightBoost=10%, you already know how dim it is, and selecting the lowest setting (0.5ms) will be dimmer than LightBoost=10%. However, selecting the highest setting (>2ms) will be slightly brighter than the full LightBoost=100%.

Really? I can't find where he wrote this. But if this is true, that's a great news. That means these monitors not only will get g-sync but also a better strobbing mode than the ULMB mode included in current g-sync modules!

Thanks again for your reply. Unfortunately I have not seen lightboost in action yet so I cant reference. Any idea when xl2420g will come out?

Can you use g/sync and strobe simultaneously?

That's exactly what one can't do at the moment, is use gsync and ulmb.
They exclusive of each other.
