Projectors & Screens

 Hi guys and girls!
Im wondering how can i connect  several projectors(e.g three projectors or more)  into a ONE big wide screen. like a very  looong 16:9. 
What kind of software do i need? 
Thanks for help...
 
 

 Can you hear the impatience in the title?
There are some great projectors out there at reasonable prices (eg: Epson Home Cinema 8350) - well priced, high performance...
and every 1000 to 2000 hours you have to replace the expensive an power inefficient lamp, which also requires a fan to keep it cool due to its inefficiency, resulting in not only expense but noise.
Now that LED replacement lights are mainstream for normal light fittings, why is it that in the projector world LED's are still limited to the post $10,000 domain?

I'm limited on WHERE I buy my next projector based on a store credit that I need to use.  The store carries mostly business projectors but they can order the Optoma line.  After research, I've narrowed my choices to:
Optoma Pro 350W
Optoma HT Series HD66
Optoma HT Series HD20
Yes, these vary widely in price, and performance...  My question is, where's the sweet spot for the $$$? 

In the next few days, I will have replaced my old Infocus 7210 and Stewart Firehawk 92" screen. I am waiting for the distributor to come and install the new JVC RS35 with Stewart Studiotek 130" screen. I have been using my Infocus 7210 for about 3 years without any complain except that, I can see the rainbow effect that sometime, will be pretty disturbing. Other than that, Infocus 7210 is a very good projector indeed.

I was looking to paint a basement wall to make a projection screen. Here's what I found:
 

This projector listed for $5K last year (I'm sure street price was even then about a $500 to $1000 less or thereabouts), but is now available for between $1.3 and $1.4K.  I pulled the trigger and expecting it on or about the 14th of August.  Does anyone own this projector and if so what are your impressions based on the best settings you've found?  This should be a very good buy on a 1080p model as it has a very full feature accompianment.

I know it's an older projector, but if anyone out there is familiar with it, I have a question.
I recently found out how to access the hidden/service menu, but can't figure out how to make adjustments with it. The sliders for color/contrast adjustments don't respond to controls. Is there something else I need to do in order to make adjustments?
 
Thanks,
Brian L. 

Hello.  I was searching this fine site to see if I could find some guidance on the optimal or correct height to mount a screen.  I recall over the years catching a few articles on the subject, but now that I am about to mount a screen, I cannot locate one.
 

How long should a lamp last in a front projector? I've got nearly 1200 hours on my Sony VPV-VW50 and the picture doesn't seem as bright as when the projector was new, and the color balance seems a little off.

Playback magazine received the following projector-related technical inquiry from one of its readers:

Comments: I am a big fan of your publication, although I wish it was still available in print form. I have a Dwin TV-3 projector that is just now in need of a new bulb. It will cost $500 to replace. I've also been seriously thinking about purchasing a new Bluray player, but I'd like to know a few things about compatibility first. The Dwin is only 720p, not 1080p capable. I was assured at the time that I bought it that it had an “HDCP compliant” DVI input.
