GTX 580 Not Displaying on my 1440p acer monitor only works with my 1080p monitor

My gtx 580 will not display on my acer predator 1440p monitor. I have tried to use a single link DVI-A cable and a mini hdmi cable(This cable says it only supports up to 1080p) and neither of them work on the 1440p monitor. They only work on my 1080p monitor. Is this not working because I need a DVI dual link cable or something else?

Have you confirmed that the 1440p display works with any other system? On the display, have you tried manually selecting the input port?

Even with a single link DVI cable, you should see an image on a working display.

I figured out my monitor has a setting that must be enabled for display port or hdmi and it was on display port
