Yaknow that must may be what happened to me too. I usually do a custom install of catalyst drivers every time. An update or so back I'd swapped my DVI cable for an HDMI. When I did, it resized my display smaller and I couldn't change it to fit my monitor properly. Drove me nuts for a couple of hours. I knew there was a setting somewhere but I couldn't remember where it was. I googled it and found I had to change the overscan setting. That's in CCC that I never install. So--I installed it, changed the setting, fixed the problem so things display right and promptly removed CCC again. The setting stuck. No problem.
Last update I just did a full install knowing I was gonna have to likely install CCC in order to resize the display again---which happened so I did. It also installed that Raptr proggie. So yeah they're both getting toasted at my earliest opportunity. Bastiges and their bloatware.
