HDMI 1440p Monitor not displaying correctly. Fedora 26

edit

Hi all, I just brought home a 1440p monitor to use. It works fine on my windows partition but is having some issues on Fedora 26.

I am using a RX 580 with an Asus PB258 and it is not looking good. I really don't know what to do to fix this, help would be appreciated.

Here are some pictures of what's happening. https://imgur.com/a/GP2ce

EDIT: I tried installing Ubuntu to see if it worked. I was excited when the monitors were working correctly from the sample OS that runs off of the USB drive and lets you install the OS. I happily installed Ubuntu because it seemed to be working. However, when I finally ran Ubuntu from disk, the monitor was having the same issue as on Fedora. Why would this be? Could it be some software update thats downloaded during installation??

Surprisingly, the resolution is correctly set as shown below in my monitors.xml file
