Hi newbie here. having problems getting my macbook rigged upto my LG 42LF7700 hdtv, im using mini dvi to dvi, then dvi to hdmi, it will not detect displays, the screen goes blue for a second then back to normal and the tv says no signal, ive tried different ports on the tv, tried to change the resolution but nothing is happening, would by buying an ebay mini dvi to dvi cable and not a genuine Apple cable maybe be the problem as im totally out of ideas and this is very frustrating, i tried it on our panasonic tv in another room and it worked fine, please help!!!!!
