I have a Samsung 42" plasma (NO HDMI, just DVI) and a unibody MBP 15" with a Mini-DisplayPort, i already owned a mini-displayport -> HDMI adapter and a HDMI cable, so i just bought a HDMI to DVI adapter for the back of the TV, plugged it all in.. didn't work..so i bought a DVI to HDMI Cable..and got rid of the adapter.. STILL didn't work.. WHAT ON EARTH am i missing here please?!? I usually pride myself at being pretty techy and have read various little snippets here and there about 2005 Tv's not being able to handshake with MBP's or something of that nature... it may even be a process of turning things on and off in the right order that i'm missing?!? ANY help at all please!?!?
