I'm new here and I've done a little searching and can't find an exact answer to my situation: I want to convert my video from my iMac and my iBook to my 37" LCD HDTV (Vizio) which has a VGA input already on it. Now, I have a Mini-DVI to VGA adapter already for my iBook, however, the adapter will not work on the Mini-DVI port on my iMac. My question is: Does anyone know where I can get a cheap alternative to convert Mini-DVI (for my Intel iMac) to VGA with at least 50-75 feet of cable? Any and all help is appreciated! Thanks!
