Graphic Card : HIS Radeon 5870, mw2 edition 850 mhz

Well, Im soon going for an Eyefinity Setup ( DVI - DVI - DP>DVI I think )

The problem is that when i tried to test my one screen with DVI (The screen is a BenQ G2420HD) it didnt appear anything on it. I connected one of my old screens to the computer aswell (using VGA to VGA-DVI adapter) I then managed to set down the resolution on the G2420HD DVI to 1600 x something and then it worked... I normally use HDMI, but if I shall use eyefinity i need the DVI to work.

You know the DVI cable, it has one part which is alot of pins 24 pins i think? And then second part which has 1 pin (and can have 4 around) The cable that I used didnt have those 4 pins around the long one.

Is it the cable that is wrong?

Usually the DVI cable should come with your monitor. So if you're using the cable that BenQ provided, it can't be wrong. :) 

Make sure you have the latest graphic drivers installed, as that can sometimes alter whether Windows lets you set certain resolutions.

My Screen is a DVI-D Dual Link
