Hi all. I joined the forum just to post in this thread. I recently got a nice new apartment with my lady friend, and as a result, a whole new family room to set up. The wall where the screen goes is 20 feet wide by 8 feet tall, so my current 40" TV looks comically small, and to say that the viewing experience is "sub-optimal" is something of an understatement. A Woot sale of a projector got me seriously thinking about projection as my new home theater solution, which naturally led me to this particular device.
My space is just about 20 feet wide, 16 feet deep, with an 8 foot ceiling. I am a n00b when it comes to this stuff so please tell me if I'm wrong, but it seems like a 100" diagonal picture centered up on the 20 by 8 wall, with a viewing distance of about 12 feet would be "the sweet spot" for the room.
Complicating matters slightly, the screen would / will be primarily used to watch HD video content, but also for gaming. At this point I have very little interest in 3D and do no planning on using this feature, nor do I plan on doing any image processing within the projector (I use a purpose-built computer for media playback, and it does a fine job of making sure everything coming out of it is 1080P/60 looking good. Even more fun, I plan on using a Kinect in the room if at all possible. It is the Kinect which partially led me to looking at a short-throw solution.
From what I've read here & elsewhere, the W1080ST works perfectly fine in terms of focus and image distortion if you don't use any zoom. To get a 100" picture with no zoom, you need roughly 72 inches (6 feet) of throw. Is this correct? If it is that would work perfectly with my sketched out setup, which has the projector installation at 6 feet out from the screen/ wall, a Kinect play area / open area from 6 feet to 12 feet, and then the couch / seating at 12 feet out. I don't "love" my Kinect, and it isn't the most important thing ever to me, its just a cool thing that I'd like to be able to use.
The only niggling question I have is, from what people have mentioned here, it seems like the W1080ST does not have a lot of play / wiggle room when it comes to its vertical placement.
People have said in this thread that the projector needs to be within about 3" of the top of the screen. Is that right? Like, if I were to mount it about 6" down from the ceiling, then the top of my image would be ~9" from the ceiling? This is the bit I am unclear on, and BenQ hasn't actually put up any documentation for the ST (the site has links but they just go to the 1070 PDFs).
The other concern I have with this unit is the noise level. Some people have compared it to some other projectors, but I'm inexperienced in this area so I have little frame of reference.
I was thinking about building a custom piece of furniture with one or two 200mm fans and some sneaky noise baffles so that the project could be actively cooled but still be mostly enclosed. This could work to reduce the noise level and also keep it safe from spilled drinks, accidents, and morons.
What do you guys think, terrible ideas? Good ideas? I am not totally against the idea of saving up a bit more money for something better, but from what people have said here, there isn't a lot of competition in the short throw market.
As I said, I'm shooting for a 100" display and my room is 16 feet deep, and I'd like to have a relatively quiet setup (my eyes aren't the most awesome but my ears are pretty sensitive).
