ok here the situation.
I have a room 17m x 19m and have to have a 4 projectors showing the same powerpiont presentation on all four screen at same timein each corner of room.

the way they are doing this at moment is having four people using four different laptops connected to four different projectors

ideally we want one laptop controlling all four projectors at one time.

first idea it to get a transmitting device to run from main laptop out to four projectors via cat 5 this runs in to £1000

then i thought about remote controll software.
Does anyone know of any remote control software where the three laptops can remote in to the main one to show what it being seen on the main laptop if that makes any sense?

like remote desktop help in windows but i need multi screen/ogin to show on screen. like teaching software?

thanks in advance
 
could you not get a couple of VGA splitters, so the output from the laptop is split to each projector?? I dont know if it would work but the theory is there?! :)
 
thanks for reply sorry forgot to add. ideally like wireless as heath and safety issue with trailing cables. it for an awards doo so will have up to 250 people walking around
 
thaks everyone for your replies. Have got a quote for a vga spliter etc...
