75hz through display port problem

[grayperview]

Ok, here is the jist of my problem

 

I have 3 AOC i2369vm connected to an AMD fury card via 3 display port 1.2 cables, since the crimson drivers where released the colour has been a mess at 60hz, but is fine at 75hz...

 

The problem is one of my display port cables refuses to do 75hz (one i bought from maplins), so i have used an HDMI cable as a replacement for now. which means I have to sacrifice plugin my TV in to my PC.

 

Also the monitor that uses this cable always flickers when in extended mode, there have been reports by others of this problem too....

 

What i want to know do you think its a bad cable or is it the graphics card? 

 

I think ill get another display port cable has i can't see why the 3rd monitor would be able to do 75hz through hdmi and not through display port

Switch the cables and ports around one at a time and see whether the problem follows the same monitor, the same cable, or the same port on the GPU.
