Does anyone else keep getting DisplayPort errors?

I have an r9 390 and my IPS display is hooked into it via displayport. I have all the drivers and stuff updated. I keep getting displayport errors saying that it can't refresh at the proper rate (60Hz) and that the resolution is bad. Furthermore, windows 8.1 keeps saying that Catalyst needs my attention but when I open it up, I don't see anything at all. SOS. please advise.
