Back when the BenQ W1070 first came out, I knew that it was going to be a contender, but since I didn't have the scratch to buy all the components to complete my home theater room, I bookmarked this thread, and figured I would catch up on it when the time came to pull the proverbial trigger.
Well, fast forward to this weekend. My fiancé made plans to host a movie night at our place on 08/03, which will be pretty hard to do without a complete home theater room. So I am now tasked to get this done for her (us) ASAP.
I got the room wired for 7.1 over the weekend, and now need to order the screen and projector. So, figuring it would be easy, I loaded this thread up, and saw that when I bookmarked it, the thread was only 7 pages long. It is now 179... Holy crap!!! Now, I will eventually get through all of the pages, but while I do, I figured I would try to take a temporary shortcut, and post the questions here in the hopes I can save myself from reading through approximately 5,200 posts in the thread to catch up.
My room is rectangular, and is 146.5" x 256". The wall the screen will be going on is 146.5" W x 102.5" H. I know I can fit either a 133" fixed screen, or a 150" fixed screen there, but I'm not sure which one to go with. Hold this thought for now...
The tricky part of the room is that it has a peaked ceiling. The ceiling is 102.5" at either end of the 256" length, and about 134" at the peak in the middle. Because of this, at the time I first started looking at the 1070, I was concerned with the throw distance, since according to the BenQ website, the throw is 79" at 2M (6.56 Ft). If my math is correct, to project onto a 133" screen, I would need to mount the projector 11 feet from the wall to do this. This would put the projector just behind the peak in the ceiling, and my concern was that the lens shift in the W1070 wouldn't be enough to correct the picture.
Now, in the short amount of catching up I have done (On page 15 currently), I have noticed that since I bookmarked the thread, the BenQ W1080ST has come out. I was on hold with NCIX for almost 45 mins today to try to get some answers from them, and got disconnected. However, I think I got the basic jist from researching while I was on hold, and it seems that the 1080ST is the exact same projector as the 1070, however, the throw ratio is less at 65.7" at 1M (3.3 Ft.). This would mean that to fill up a 133" screen, I could mount the projector at 6.68 Ft away from the wall, which would mean I would need less lens shift. I spent around $900 on my screen from Amazon.
So, here are my questions:
1) Are my assumptions thus far correct (1070 versus 1080 ShortThrow)?
2) I have read that the 1080ST doesn't have lens shift, however, I see on the BenQ page that it has Vertical Keystone Correction of -20°/+20°. Is that the same as lens shift?
3) Given the size of my room, and the location I would need to mount the projector, should I go with a 150" screen, or stick with a 133"? I know seating location is somewhat subjective, however, I'm sure there is a generalized standard among you experts, so please instruct the layman. :-)
4) I was planning on going with the monoprice screen (PID 7957). For $480.50, it's a great deal, but do you think I should get something better, and if so, what? I really would prefer not to spend more than $800 - $1000 on the screen.
Thanks very much in advance to everyone for your help. I'm in a tough spot, and need to get the stuff ordered within the next day or so, so that I can work on installing it next weekend.
Looking forward to your responses!!!
