I just upgraded from a HD6970 to a brand new R9 290 which is for me the best deal ever concerning the power to price ratio.
Nonetheless I experience since the install an overscan at first on my desktop which I took care of using the CCC and overscan feature (noting that my screen can only go up to 1080p and the overscan occured with the reso being at 1080P!!!)
Then and that's the main issue all my games are being overscan if i don't play at 1080p and some game HUD become unreadble at 1080p and some other can't even reach that resolution.
My spec as is
latest Catalyst driver ( note that i tried at first with the vanila driver and had overscan issue)
Thanks for your help
