Hi everyone, does anyone know of a way to output video from a MacBook pro to three different projectors (from just the one computer? Is there a lead that goes from the laptop to three ends (rather than the usual 1)?
Cheers

matrox triple head to go is probably the most common way
you cant just split the copper.

yeah, matrox is the way to go for 3 split. right now im using a 2 projector setup but utilizing the pass-through (image duplication). anyway, here is some patcher stuff that might help if you pick one up. basically 3 windows and a full-screen toggle ;) keep in mind installing the drivers for the matrox is a HUGE pain in the ass and as sensitive as a skunk humping a hedgehog; one bad poke and the week is ruined.

Would it be possible to use one of these for a macbook pro? http://www.maplin.co.uk/svga-splitter-2-and-4-port-36773?ordercode=A94BB

If you want to just send the same image to 3 projectors then yes, use this sort of thing. Some projectors will also have a monitor output that can send on whatever is coming in to another projector/monitor so you can just daisy chain them.

If you want to split an image across the 3 projectors you'd need a triplehead2go.

The box you linked should work fine with a MBP VGA output, but if you are concerned just ask Maplin a question at the bottom of the page you have linked.
