Displayport Error... PLEASE HELP!

Hi Guys, 

 

So im having a problem here.. 

 

I bought a new projector for my setup, my Graphics card has two DVI ports, one HDMI and one Displayport. 

 

Up until now i've been using the HDMI port for my monitor but I now need to change his and use the Displayport for my monitor which also has a Displayport as the Projector will use up the only HDMI port.

 

However, when I connect the Monitor with the Displayport cable I get an error saying: displayport link failure. 

 

I Dont know what the problem is, I've tried using another brand new cable and it still doesn't work. I updated all the relevant drivers.  

 

Here are the Specs to my Rig:
