Help with nvidia gtx 550 ti

[d_m]

Just build my first pc yesterday, installed the video and mobo and monitor drivers.. Trying to get my viewsonic fuhzion 120hz 3d monitor to run 120hz but when I checked 120hz it created horrible blurryness and tearing on the screen then began flickering -- I don't think it's the cable, video card, or monitor -- I just think there's a little tweak I'm forgetting to get it to work -- any help? Can't get it past 60 hz

What connection are you using? You need either dual DVI or display port to make it work.
