How can I show my keynote presentation from jailbroken iPad 2 on the premethean board

[Janes]

Pretty self explanatory, I can buy a VGA cable and I have the jail broken app "displayout" could I use those two things to show it on a promethean smart board from my iPad 2?

I'm not familiar with the premethean, but I have the same setup otherwise and show keynote presentation from my iPad on a variety of devices at customer sites. Assuming the cable connects to it, I don't see why not

Hope that helps.
