Ok,My issue is that there is a weird horizontal line during video playback on the DVI ports,Well it looks like video over lapping line.Doesn't do it on the Mini-Display port or out the HDMI.It's really hard to explain.
And this with any video played on those DVI ports(Including Youtube)

Since I couldn't get any help here.I went on a rampage to find what the problem was.
And I guess the problem I was describing was in fact called TEARING.
Well I solved it by updating .NET 4.5
And in the CCC Video section,Putting a check in the box(Apply current video quality settings to internet video).
Oh,Also I turned AERO back on too.
All these thing help to fix the issue.
