I just bought a new 24 In IMAC and have a question about the whole mini-dvi to hdmi? I bought an adaptor that stated it was a Mini-DVI to HDMI converter. However when I went to plug the Mini-DVI part into my Mac, the part was much to big to fit into the slot. Are there different sized Mini-DVi's??? I am a bit confused right now...I was then going to run and HDMI cord to my TV to watch some show on there......Thanks for your help.
