I guess I am retarded because I cannot get the dvi to video adapter (http://manuals.info.apple.com/en/MacBookPro_15and17-inch_Core2Duo_UserGuide.pdf) to work. So I connected the DVI to Video Adapter to my computer then I connect a video cord to the adapter and plugged it into my tv. Then I opened the system prefernces then clicked displays and then I clicked detect displays and nothing happend. Nothing showed up on my tv. I went and bought an s-video cord because I thaught that the normal yellow video cord would work but it did not . I would appreciate it if someone could help me out. Is there a step I am missing or not doing correctly.
