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
My computer is an i7-4790 with 16GB RAM, my GPU is Radeon R7 370 4GB, and my monitor is DELL U2713HM. I have tried using the HDMI cable and also the DisplayPort cable. With either cable, the max resolution I see is 1920x1080. Am I doing something wrong? Or are my components not able to recognize 2560x1440?
U2713HM, how to set max resolution?
