hi, ive just purchased three monitors the same.. they all have dvi connections, how would i go about setting them up to eyefinity.. i know i need a active dispaly port adaptor, seen a sapphire active dvi one, on amazon for about 20 english pounds.. is it then just a case of 2xdvi, adaptors going to the other 2 monitors, or is there something else im missing?? thanks for looking..
