Hi all, just ordered a Macbook and the mini DVI to DVI adapter to go along with a 20" Viewsonic external monitor. My question is what gender DVI cable will I need ? Does the apple adapter have a female DVI port ? I want to make sure I order the proper cable. The one I am looking at is male DVI-D to male DVI-D. Will this work for me ? Also, what is the difference between single link DVI and dual link DVI and which would I require ? Thanks.
