I'm trying to connect my Macbook to my HDTV and I followed all the research I did online. I am using a mini display port to DVI adapter then a DVI-HDMI adapter. The computer registers the TV and its settings but the TV is saying NO SIGNAL. Its all plugged in correctly and I'm in the correct input and still NO SIGNAL. Could my DVI to mini-display be bad? I also tried the mini-display to DVI with a DVI to VGA and VGA chords into the TV and still no signal. But the computer still registers the connection in My Display panes. HELP!
