Hi all,

I really hope someone will be able to help me.
I have Alienware 15 R1 (970m - Display port at the back) and also I have purchased Acer XB280HK couple of days ago, and I am not able to run it propely.
I have connected them via MiniDisplayPort to DisplayPort cable.
Monitor shows "NO SIGNAL" message when on anything higher than 24hz.

 

What's the issue? I have purchased pretty cheap cable. Could that be an issue?

Any help will be appriciated.
