Having bought the new GTX 640 grahics card, my friend asked me to install this card in his pc. To my surprise, we could not connect the existing dvi cable to either of the two dvi outputs on the card. He also had two dvi adapters (dvi to vga & dvi to hdmi) which we also tried and failed to connect. He is currently using the vga output. Having looked closely at both the dvi cable and the graphics card, the issue seems to be that the flat metal pin hole (on the left of the card ouyput) seems to be too small on both outputs to sccept the wider metal pin on the cable/adapters. So as far as I can tell, this seems to be a manufacturing issue. I did not want to use a blade or such-like to widen the hole for fear of damaging the connectors. Has anyone ever come across this as I know I havent and I've been building pcs for for two decades.
