*Gulp*


Okay I've made the plunge and bought an NEC 6pg Extra (1500 hours) with the point convergence board for $650.


However, I have a problem in that I wish to mount it on my ceiling but I have no idea who would be able to do this.


I'd make a meal of it if I tried it myself and the local AV shops arent too interested because they only want to set up projectors bought from their store, and they only sell LCD. So even if they were willing I don't think they'd have the expertise or know how to mount a CRT projector anyway.


One idea I had was getting a builder to come in and mount the thing on my ceiling for me according to this installation guide I found for the NEC 6pg

Then after the pj is mounted get the screen installers to come in and install the screen according to the same specs?


Is this a crazy idea, are there any better ones? I'd like to know what you would do in my situation.

It's probably going to be easist to try and mount it yourself, and then hire someone to come in and properly adjust it for you. Make sure when you mount it that you get the proper distance so that it can be setup properly. Try contacting Jeff Bryngleson for the calibration, he is one of the best.


Thanks!

HI,


Sounds like you got a nice deal on that projector.


Here's some advice from me to you. Set up the projector in a table mount position first. Sometimes these installation diagrams are off for one reason or another. Sometimes you need to move the projector closer to use more of the phosper. Trying to use most of the tube is a good idea since it benifits resolving capability and brightness and won't wear a small portion which could be a problem if you ever change the mounting scheme.


I've seen some website where people make thier own mount. I used a mount designed for my projector and then added some unistrut so that I could fasten to more than a single structural member.


Be carefull if you do it yourself. (And be carefull if someone does it for you. Some "pros" may be suspect.) It's libel to hurt or kill someone if it falls unexpectedly. Even if no one's around it could break the projector.


Good Luck,


Brian

If you want a great (and inexpensive) way to mount a projector, do a search on 'unistrut' in this forum.


It'll give you a simple inexpensive way to mount the thing yourself, plus give you some flexibility once the thing is mounted (which none of the other ones do).


Once you've read a bit, if this looks like something you'd want to undertake, send me a private mail with your email and I can send you a full set of instructions that someone else had written up for unistrut mounting.

The answer will depend on how your ceiling is constructed. If you have a joist at the correct spot, you can consider mounting it yourself, otherwise, figure out where you want it, and have a carpenter work out a mount. If it isn't securely mounted to the building framing, it's a hazard.


In my case, I had just three ceiling joists and no ceiling, so I sized the screen based on where I had to mount the projector, rather than the other way around. Here's a photo:

How high is your ceiling? What is it made of? Do you have solid studding in the ceiling? Do you have metal girders that unistrut can be attached to? There are very good ceiling mounts for your pj that are made by such companies as Progressive Marketing or Chief. Make sure you get the proper distance from pj to screen.

Okay then, if I put it up myself or decide to get a builder to put it up for me what sort of distance should I put it back from the 92" 16:9 screen? The ceiling is 8 feet high and is plasterboard (I think you Americans call it drywall) over the wooden timber beams of the ceiling.


I'd use that installation chart I posted above but can I trust it.

Macksta,


A CRT projector's throw distance is based on the screen width. Therefore your 92" diagonal 16:9 screen is 80"wide x 45"high. Now to equate this for your throw chart you use a 4:3 screen and plug the numbers back in. 80"wide x 60"high giving you a 100" diagonal. Now when you go back to your throw chart you simply use the 100"screen measurements.
