I have an imac bought in October of 2007, and a Mini-DVI to video converter, namely this one http://store.apple.com/us/product/M9267G/A I can get it to work in OS X, but when I try it in XP Professional SP3, my screen is black and white, with lots of distortion, and it looks like there are 4 screens vertically. I have been trying to do this for a couple weeks now and don't know how to proceed. Could someone spare a few words of advice. Thank you in advance.
