Hello all. I am getting so confused on the setup of my media room. I am having a new home built, and I am required to have the builder do the wiring. I am trying to get all of my calculations together before construction starts, so I can have them wire everything to what I want. The room is 16wx20dx8h. I know I want the Pana ae4000, but I am getting confused on the different suggested mounting specs and screen size. I am between a 106 and 110 16.9 carada criterion. I have been trying to play around with the projection calculator pro, but am not understanding it. I guess my biggest concern right now is deciding the screen size as the builder is installing in wall speakers, and I want to make sure I can get the biggest sized screen possible. What is the correct placement of the screen from ceiling and floor? I have seen 1 foot down and 3 foot up. If that is the case, then I will not be able to get either of the screens I have been looking at (106" Outside Frame Dimensions is 58.6" high). The next concern is how far back to have the conduit installed for the pj. I do not plan on having multiple rows of seating, and will only have one couch/recliner that I hope to be able to place just right for viewing. I wish things could be the other way around and I could get the pj first and then determine screen size, but unfortunatly I have to go this route. Thanks for your help, and sorry for such newbie questions!

I am having a new home built and will have a dedicated room for a pj. The screen size I am working with is 106" diag. The problem I am having now will be choosing white v gray and the gain. I know you get what you pay for, so I want to purchase something that will not look cheap, but not break the bank. 1000-1500 would be a good starting point. I know there are factors in dertermining a screen as to what material you watch. So, (my wife calls me a hobbit) I will have all windows blacked out to control ambient light. I will be using the pj for bluray movies and ps3 games, and some football (will control the light, but will not have windows totally blacked out) The room size is 19'7x16. Right now my pre-wire will have the projector at 13' back. Can anyone give some much needed suggestions/comments on this new adventure? I know the answer I am looking for is probably in another post, and this question gets old answering it over and over, but I couldnt find the answer I was looking for. Thanks in advance!!

In the upper right hand corner of the image I've noticed a transparent circle is apparent whenever there is a black image on-screen. It almost looks like a water spot of some sort, yet I see nothing on the lens of the projector. Also next to this spot is a light, white-ish speck, which almost looks like a piece of dirt. Both of these anomalies are only visible when the projector is on, but when there is no signal going through it. Once the picture comes on, you can't see them, even in dark scenes, or if when watching a 4x3 picture. The spot should be in the black area to the right of the pillar boxed image, but for some reason it's not visible during the playback of a movie. This is a good thing, of course, but I worry that this is a problem I should look into while the warranty is still active. What can be causing this? Again, I don't see anything physically on the lens. Could this be a problem internally with the projector and could it get worse? I've only had the projector around 3 months, I always keep the lens cover on it when it's not in use. It is ceiling mounted. Also I've cleaned the air filter every 100 hours of usage. It's been a great machine except for this one hiccup.
