I just picked up a Dell 2711 at Frys for $200. I know it's old and not the greatest but for the price I figured why not. If I don't like it the wife can surely use an upgrade. My question is, in order to use 2560 x 1440 do I need to use DisplayPort or can I use HDMI? I guess DL DVI works too, but I only have a single link DVI cable. I appreciate your input.
