Well they put out both a composite and video to a DB 15 port. The main thing I have heard is the LCDs have to sync down to 15khz. If they can do that it should work.

These simple moulded adapter plugs for the Mac, that have DB15 on one end, and VGA on other should have the green sync up.

I have seen these with all kinds of switches on them. Have not investigated to what they do. Seems they have to do with the higher or lower numbers of the video display. That is to match video. Not sure how they do it.
