I bought a new LG 2560x1440 144hz monitor early this year. I'm running a R9 Fury X and from the day I got the monitor and plugged it in it was instantly recognized as 2560x1440 by AMD and Windows. Now all of a sudden neither AMD or Windows will recognize its resolution and I'm getting terrible FPS. It will only recognize my resolution as native 2560x1080. I haven't updated any drivers or changed any settings, it was just like this one day. How do I get it to revert? There is no option in windows or AMD display settings for 2560x1440, only 2560x1080. .
