well I find it hard to believe that anything looks better on DC2 than on DC3.
we know the difference between DC2 and DC3, it's been explained in a technical PDF from TI.
the back of the chip behind the mirrors is flat black on the DC3, which means less mosquito effet.
the fill ratio is increased, so less inter-mirror space, and the CR is also increased because the mirrors can spin a tad more and their coating has been improved.
higher native ratio = better shadow details.
when the BenQ employees talk about DC1 in the W5K, and DC3 in the W20K.....I'd say they have no idea what they are talking about......or we've been lied to for quite some time
the diff between the HC1100(DC2) and the HC3100(DC3) is pretty minimal.....same lamp, same mineral glass optics.
the only difference is in the optical path, the 3100's being a tad more polished....so that would explain the black level being so low....yet the 1100 has way less contrast(less 3D like), and its mosquito effect is striking
