RE: Alienware 18 with dual AMD 290x connected to Asus pb287q 4k monitor goes on and off -unusable

I'm so sorry KurianDungu but I don't have a solution for your problem. Only a question. I have an Alienware 18 Laptop. And 2 x R9 M290x GPUs. But when I install catalyst, there is no option to turn crossfire on or off. And in information/hardware, it has primary adapter, and disabled adapter. Leading me to think something is definitely wrong and crossfire is not turned on, on my machine. Where did you get Catalyst Control Centre, and which version of catalyst control centre are you using?, because mine is definitely, not showing anywhere to turn on crossfire. Dell have tried countless versions of catalyst through tech support but nothing will show my crossfire is on. I just want to give them proof that you have the ability to turn crossfire on, and have the same laptop, (basically) as me.

Thank you
