[thelist] Controlling displays on mulitple large plasma screens

[fstorr]

Hi all

This is probably OT, so I'll have to think of a tip, but my company is 
looking to purchase 5 large plasma screens to put on our office walls 
(spread over 5 floors of a large building).  We're going to need 
something to control the output to these screens so that we can, for 
example, turn off display to screen 3, or show the same presentation/ 
output to all five.  The idea is that we can use this for presentations 
to all our staff and also show looped content of, for example, online 
news pages or other content during lunch hours.

Knowing nothing about this at all, I've been given the task of trying to 
see what's out there.  Is there some kind of app/system/thing that 
exists for what I'm after, and if there is, can I get some pointers?

Regards

Francis
