Pros: Good image quality, Easy to setup, Relatively quiet
Cons: Black levels, Button layout, finicky HDMI input
When I came across the W1070 and read the reviews I finally decided to pull the trigger - it cost less than $1k and seemed to offer a good mix of product characteristics, with the caveat that I might be unhappy with the "rainbow effect" which seemed to plague DLP projectors like this one (it proved to be an unnecessary worry - to this day I still have seen no rainbows to speak of).
Because I also have a 60" plasma in the same room I have not used the projector as much as I'd like, since for casual viewing I end up defaulting to the TV. On the other hand, having this setup allows me to have a more critical view of the shortcomings of the W1070 compared to a positively good panel.
Without further ado, let's take a look at the how the W1070 has performed for me so far
I bought the 1070 in April knowing that I'd be moving in June, so I did not bother to mount it on the ceiling or to put the screen in place. Even on a tabletop, however, it was fairly easy to adjust it to have a correct image without resorting to keystone just by fiddling with placement and using the (limited) lens shift capabilities. Once I get to the new house I'll mount it on the ceiling, but given my previous experience I do not expect to suffer a lot to get it up and running correctly.
Because It'd be operating in a completely different environment in less than 3 months, I did not bother to calibrate the projector beyond changing the modes and finding the one that best approached the image I get out of my panasonic plasma. I could get good color reproduction and general wow factor that were comparable to the plasma, but lack levels are noticeably worse (note: my friends who use regular LCD / LED panels did not notice this, but since I had a plasma to compare it was hard not to notice the difference).
Awesome. That was my first impression after using this projector and is one I saw echoed whenever one of my friends came visit and saw the setup for the first time. In the NCAA basketball final I had my living room setup with the panasonic and my regular HT gear (including my couches) and the dining room with the W1070 projecting on the untreated wall with a set of Bose bluetooth speakers (which were enough to play over the 1070's fan noise) and some folding chairs and most of the people ended up watching the whole game on the W1070.
Some compared the image in this scenario (projecting on a beige wall) favorably with their own TV setups (consisting mostly of LEDs or Plasmas in the $1000 range) based not only on the increased size but also on the color reproduction and the overall image dynamics.
Two points that could improve in this projector are the buttons in the projector body and the HDMI inputs. While the button setup looks good and compact at first, it has proven relatively hard to use by touch only - they all feel the same and for some weird reason the volume of the built-in speakers is changed with the left and right buttons rather than up and down. This is a minor flaw that does not show up when using the remote but annoys me whenever it happens. The second point is that the HDMI input is quite sensitive - if the projector is on a table and anyone touches the HDMI connector plugged into the projector chances are it will lose signal and display a blank screen. Since this just happens when the HDMI cable is exposed, I do not expect it to be a nuisance once I get it on the ceiling support with the cables tucked in the ceiling, but for those who intend to use it on more mobile applications might care about this.
In general I really like the W1070 - I cannot imagine that any other projector in the same price category would deliver a better bang for the buck. Even though the black levels are not spectacular (thus taking one star off the overall grade) I wholeheartedly recommend it for anyone who wants to get a good quality image on a large screen without having to sell the car for it.
