I got a macbook pro 15 2.3 i7 with a thunderbolt to dvi connector, i need to connect my mac to a Barco full hd projector, i tried with a 15 meters dvi-d to hdmi cable then i pluged an hdmi to dvi conversor but i had a lot of issues, lost of signal flickering so of this way doesn't work, now i have to get a dvi to dvi cable, what kind of cable do i need? dvi-d? no more than 15 meters right? do i need to set up the preferences output in my computer of any special way? any suggestion?
