So I am upgrading my monitors...I am getting four 27 inchers that run at 2560x1440. My current PC has 2 video cards and each have 2 display port connections. These monitors I'm getting only come with dual link DVI and VGA connections... So, I'm wondering can I get an adapter and run the dual link DVI cable into an adapter that plugs into my video cards display port spot? I have read where these signals are not the same, but other things have said it will just pass the signal through to my video card... I'm confused, and would rather not have to buy new video cards if I don't have to... Thanks for any insight.
