XL2420T has slower and older panel, only supports 120hz(asus does 144hz) and doesnt have adjustable overdrive, it's AMA ON is really agressive and brings a lot of trailing/ghosting after moving objects
Interesting to hear, although I'm not sure i agree with your comment about pricing: the vg248qe is around $270+tax+shipping, while the XL2420T is about $230 total, so around 15% cheaper. Granted, you did say around the same price :)
In any case, I'll post some details about how I like it when the Benq shows up on Monday.
After reading the Benq listing more closely, I'm actually hesitant to think that this is a refurbished unit - when you look at the Benq Outlet store, there's a separate and distinct link to a "true" refurbished XL2420T unit, which is priced much cheaper (approx. $100 less). That makes me think the one I linked in this original post is a lightly-used tournament monitor, while the "true" refurbished unit has been refurbished in the traditional sense. I've emailed Benq to confirm.
Confirmed - the one i link in this post is NOT refurbished, and has simply been used as a demo unit at an MLG tournament. It comes with a 90 day warranty in case there are any defects/issues.
