Help! 2 VGA-one laptop

I have a MacBookPro 10.5.6 laptop + Max 4.6

I want to have different video sequences playing on two video projectors at the same time using only the laptop.
The video sequences will be triggered in relation to the inputs of my sensors.

Should I buy a Matrox DualHead2Go?

and a video card?

Should I use the jit.display ?

Any help will be soooo much appreciated.

Oh and my sequences are very short 10 sec and in low resolution 320 x 240.

I hope this is possible……

Dear MJ,

Thanks a lot for your reply! in fact, I did a lot of research before posting. This is one of the reasons why I bought the matrox dualhead2go and look up at the MultiScreener and Mietzplayer.

Well, I was a bit confused about this statement:
“You could use two video cards for this, each with two outputs (or one with one and one with two) so that you’d still have your interface patch on the regular monitor. I don’t know of a vid card with three outputs, but they may exist…?”

I am a novice at this and I would appreciate any clarification or

* and I will post my patch very soon. _

I have been struggling so much. I would be very grateful for any suggestions.

I bought a Matrox DualHead2go to be able to have two VGA outputs. The problem now is that I can’t find a way to project 2 video at the same time in one fullscreen.

What would be the easiest way to split a fullscreen in two? * I tried to place two windows in the screen with a pak size and pak pos but the problem is floating has no effect with border off…. any other easy solutions for this…

Many Thanks
