I have found articles on this but no strait answers on how to fix. if i dont have my AMD radeon software installed i can run my monitor at 1440p. But when i have it installed it removes that option i am using a DP. And i know its not the cable because 2 things one I have tried another one and HDMI as well and also when radeon software is not installed it works just fine. tried older version and this has been a problem from the beginning (about 9 months or so) so its not because of a recent update.
any help would be much appreciated getting tires of not using what i paid for XD
