Two 21:9 monitors [Need Help]

[Jaycob]

Hey guys,

I've been using a Crossover 290M (2560 X 1080) for some time now and decided to get a second one but it seems my GPU won't power the second one I got this morning for some reason even though it has two Dual Link DVI outputs. The GPU is an ASUS 7970 DCUii

Both monitors are working and work fine with one of the Dual link DVI ports same cables and everything.
I've tried using the switch on the card to switch between single link DVI and Dual link DVI but to no result.

I'm just wondering if anyone on here has two Crossover 290m Monitors and if so what are you using to power them?

Here is a pic of the setup if you're interested: Image
The monitor in the middle is hooked up to a laptop hidden under the desk.

Many thanks,
Jay
