I just received my BenqW1070 yesterday and installed it in my living room (bright room, white walls with blinds that can make it just a little darker during the day).
I am going to mainly use this projector for watching 2D and 3D movies as I have a 70" LCD TV mounted on the wall behind my projection screen.
I wasn't really sure which screen to buy, I knew that I needed a 100" diagonal and that I wanted a portable one as I did not want to install anything on the wall there. I ended up buying an Elite ezCinema screen which by the look and feel of it is quite "basic", or a little cheap.
The screen upon first pull-out had wrinkles (more like waves) from side to side. I called Elite and they told me that it's ok and that once I start watching movies, I won;t be able to notice it, which is semi-true, I did manage to see it when I watched scenes with horizontal camera pans.
It works well but I was wondering if there was any better option for me out there, a different brand that has better screens of the same kind.
I am attaching a few pics of my setup and the waves.
