I'm trying to hook up my IMAC mini-DVI port to my Samsung HDTV. I have a (mini-DVI port to HDMI) adaptor plugged into a 15' HDMI cable. This plugs into the TV's (DVI/HDMI) port.
I also have a 15' audio cable plugged into the MAC's headphone port then to the TV's (PC/DVI) audio port. Nothing works, video or sound. TV says no signals detected. MAC doesn't know it's connected. Does anyone have the slightest idea as to what the problem is? Do I somehow have to activate the mini-DVI port?
