I have an old 20" apple cinema display that I would like to hook up to my Mac. I purchased a VGA to mini-DVI adapter to hook it up through, but when I tried to connect the VGA side of the adapter i found that hey did not match. I was wondering what port this possibly could be able to hook up to, and why this ACD has such a foreign port, as I thought apple used VGA for video input. Here are pictures of the 4 cables that run from my ACD. Also, do all 4 of this have to be connected for me to use this monitor? Thx in advance.
