Hello gents.


I'm at the beginning of construction on my theater and I'm entering the final stages of wiring. I've stepped back for a moment to try to ensure that Ive done all I can Before I move on to a point where going back will be maddening. I have been going at this from an ease of updatability stand point, so with that in mind here we go.


My room is 16X11 and I'm planning on using a 60" Sony rear projection display that I have had for a while when I finish the room. I am however trying to prep the room for a front projector upgrade in the future. I've run HDMI, component, and power wires to a prepared location (in ceiling mounting plate) for the projector. it occurred to me that I may want to have a motorized screen, however I am unsure how to setup the room for this.


Is the wiring on the screens standardized at all like always on the left or right?


Are most screens universal in that respect so that they can be wired from either side?


What type of wiring do I Need 110VAC, 12VDC, remote wiring, etc?


between which locations do I need to run wiring, Projector-to-screen, screen-to-equipment rack, screen-to-wall switch?


What else have I not even considered because I don't even know that I don't know about it!


Your help is greatly appreciated.

not sure if there is a standard side, but mine is on the left... when looking at the screen from the front....

The A/C Connection can be on either side. I had an Elitescreen as my first screen and the power was on the left hand side and when I had an issue with it they replaced my screen with a different revision and the power was on the right side on this screen.

Personally I'd consider 120V A/C outlets on both sides. I would also consider the largest screen possible as what may seem large at first may not be later.


If you can, run your wiring through conduit so you can change later. HDMI 1.3 is standard now but 1.4 will carry more bandwidth which may be beneficial for 3D. Some people also run Cat5/6 as well as HDMI can be run over that as well.


You could run 12V triggers to either the screen, the projector, or the A/V receiver. It just depends on how you want to set it up.


If you think you might want a Dalite High Power screen your projector will give the brightest image at eye level. I say this only because this is a popular screen and a typical ceiling mount won't work for this type of screen. Better to think about this now that later if there's a chance you may be interested.


Don't forget to guesstimate your screen size when setting up your room. Do you want a false wall? Will you be building a stage? Where will your subs be place? etc. Your placement of your setup could affect your screen size. Weigh this all out first and be sure to do the same for speaker placement. I wired my speakers too high when I did mine.

I'm certain I've read that at one time perhaps I am wrong. Here's the new 1.4 upgrades:

I've run empty conduit from the equipment rack to the projector location thinking that I'll run what I need when the time comes. regarding the screen, it seems to me that all it requires is power/low voltage trigger so I would run that together and just have to figure out were to terminate the other end of the trigger. I suppose that an outlet box on both sides and running the trigger to all possibilities is do-able however I was hopping not to have to go to that extent.


regarding the trigger do most screens have a relay mechanism built into them? cause I assume that the low voltage works a relay and not actually powers the motor that works the screen, or is it necessary in most cases to have to add this mechanism externally? are these units supplied with the screen?


regarding the ceiling mount thing I have seen some screens that are specifically designed for this, with extra black out material on the ceiling end to accommodate the extra drop the screen will have to reach.

I think some of your questions are "all depends" on the screen and the manufacturer. On a cheap screen like Elitescreens many of those options are standard. On the better screen you typically have to pay for each extra feature like a 12V trigger, extra black drop, etc.
