So I bought another displayport cable, this time it is a 1.4, the previous one was 1.2 and it still did not work.
Then I realized I needed to toggle the input via the buttons above the power button. It was set to HDMI, and I figured the monitor would auto-sense the input..

So the cable was not the problem..
But it's fixed now and i have 2560x1440.
Thank you

The online 2012 U2713HM User's Guide states on page 3 that the HDMI 1.4 port can only do up to 1920x1080.
The U2713HM DP in port should be able to do 2560x1440.
The 2015 Radeon R7 370 DP out port should also be able to do 2560x1440.
Be sure that that you have the latest AMD Radeon driver installed. Consider testing another DP to DP cable.
