Ok Dolphinc, I'm back. Sorry this is taking so long.
After moving the Optoma out of the way, we set up three 100 inch images. The first was the benq1075, next to it was the Epson hc3500, and next to the 3500 was the hc3000.
To start with, all three projectors are really bright. You can probably watch any of these in a fully lit room, though in most situations, keeping these projectors in Eco mode mode should be more than bright enough. Between the 3500 and the 3000, I don't perceive any real differences in brightness between the two. I know for sure that both projectors run at the same power in Eco mode.
In terms of black levels, all three look about equal. The Epson's will give better blacks and contrast when the dynamic iris is in use. The Benq can probably match the Epsons in SmartEco mode or at least get close enough that the differences are not worth talking about. Although it's a very subtle difference, I thought the Epsons had slightly better shadow detail.
Where these projectors really differ is in color and sharpness. Even with the Benq's brilliant color turned on, the Epsons have brighter, punchier colors. The Benq's color seemed a little dull by comparison.
On the other hand, the Benq was a little bit sharper than both projectors even with the 3500's super resolution turned all the way up. The 3000 doesn't have super resolution, but can still get very sharp. (about as sharp as Super Resolution set to 2 out of 5) All three are sharp, but the Benq is the sharpest.
The Benq also still has an advantage in motion blur. The new Epsons are an improvement over earlier models, but lack of any CFI still put them behind the Benq.
We didn't run any of these projectors in 3D, so no comment.
In terms of projector noise, the Epsons were a little quieter, but none of these projectors are what i would consider quiet projectors.
To sum up: All three projectors are excellent performers. Although they have different strengths and weaknesses, i really can't say one is a better overall performer than the other. So your buying decision comes down to weather you need lens shift or if you're sensitive to DLP rainbows.
p.s. When i saw that the Benq's colors seemed a little dull to me, i turned on the 1070 (which was nearby) to compare with the 1075. Sure enough, the 1070's colors seemed to be slightly more vibrant to me with both projectors set at the same default. I had to turn up the 1075's color saturation up a couple of notches to compensate. Since there's no big differences in bulb life, i'm thinking the 1070 has slightly stronger color. I could be wrong.
That's all. Hope this long winded explanation helps in your decision.
