Strange mini-DVI display problem!

At my work we've got some new Intel iMacs and are using a couple of them attached to projectors for secondary/mirrored displays. We are also using bootcamp on both as well. The problem is that on one of the iMacs (the other is fine) we can't get it to detect the second display. The strange part is that during the boot screen, it will pop up briefly on the projector then disappear. Once the OS has loaded, I'll hit the detect displays and it will flash briefly again like during booting, but this time has this fuzzy/wavy/out of phase look. Also, when I go to system preferences and then click displays, there is not an "arrangement tab" for making any adjustments. I've swapped mini-DVI adapters but that didn't solve the problem. Oh and one last thing, and this one is the real kicker....When I boot to Windows, the secondary monitor works 100% perfectly fine.

Well, I think that covers everything. Hope one of you out there can help!
