Cannot Set XL2411Z to 144hz

[Aiden Thursby]

I have just bought a XL2411Z, I installed all the drivers and bought this cable http://www.ebay.co.uk/itm/191294025760?_trksid=p2060778.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT I connected it up with my monitor and when in windows went to Screen Resolution > Advanced and selected 144hz I am running windows 7 Ultimate BTW and I have done literally everything I also used another cable which was like the DVI but had a Positive slot at the side of the pins and was white and not a negative like my Dual Link Cable

Are you sure you are connecting the cable to the Dual link DVI port on your graphics card output?

Yes i have plugged the DVI cable into the right port on my monitor and GPU

Also when I go into the Nvidia control panel and create custom resolution it says "Resolution: 67.50 Hz" On the left bottom side

Nevermind, it changes
