This is my first foray in to digital projectors and seek some advice;
The room I want to install a projection system in is 14 1/2 feet long 12ft wide I am looking at either the BenQ W1070 or 1080ST with an Elite ELECTRIC84 Electric Projection Screen (84 Inch 16:9 AR). This room has shutters which can shut out most of the light making the room fairly dark.
This system will be used mostly for Blue Ray/HDDVD movies and HDTV and get about 3hrs a day usage normally, at least until Football seasons starts then Saturdays and Sundays will probably double even triple that.
The screen will be mounted on one of the 12 foot walls the seating will be 10-11feet from that wall. I want to shelf mount the projector on the back wall behind the seating area. I am looking at an OmniMount Tria 1 B shelf for that as it is adjustable in 1 inch increments which could prove handy when initially dialing in the image on the screen.
Here is where I start to get confused; I checked http://www.projectorcentral.com/projection-calculator-pro.cfm
it shows the 1080ST for a 84inch screen has a throw distance of 4 feet and the W1070 has an 8ft throw, however the distance I will need is closer to 13ft.
Is the throw distance calculated the minimum?
Meaning I could still place it near 13ft from the screen and dial in the image but it might not be as tight as it could be?
I am going to use my receiver to control HDMI inputs so will run a single HDMI cable to the projector is there a limit on HDMI cable length without the signal degradation?
The other question I have would be screen size there is also a 85 Inch 16:10 AR version am I losing anything not going with it instead?
Thanks for any advice.
