3 way projector output


    Apr 12 2011 | 10:20 pm
    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 J

      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.

      I've got a 3 screen multichannel patch/app hosted here (based on Vade's patches) http://www.aranarproductions.com/enable.html
      Pardon my craptacular website... Desperately needs an update.
