Not sure if this is the place to ask this, but I figured I would try everywhere. WIndows installed 8.1 Pro on me, and apparently it will not support 2560 x 1440, or at least I cannot get Catalyst to recognize it. My 27" Auria worked just fine at 2560x1440 before 8.1 and even after a reinstall of Catalyst, it will not even show as an option. I've contacted the nitwits at Microsoft to inform them of this problem, but the customer support over there moved me from person to person who had little to no idea what I was even talking about for screen resolution, therefore , they concluded it must be a driver issue. If anyone has any suggestions, or ideas, I would love to hear them, since I am completely frustrated at this point. Thanks for the time and effort in reading this and I look forward to any responses if they come.
