Nostalrius Begins - Quality wow vanilla realm (1.12)

Anyone have this issue? Was working the other day now it's not. I switched from HDMI to Displayport

Do you mean 2560x1440 or 1920x1080? Are you only getting resolutions up to 1600x1200?

No, my resolution is 2560x1080p. I was in that resolution last week and all was fine. This Saturday I logged on and I was stuck at 1920x1080. Changing the .wtf file to 2560x1080p or reinstalling doesn't help.
