Hello all,
I have an Acer H233H monitor connected to my Radeon HD 6670 graphics card and had black bars around the edges at 1920x1080. I fixed this by increasing the overscan, but the problem reappears every boot-up and I have to lower the overscan then raise it again to fix it. Any suggestions as to how I might make this problem go away completely? So far I've tried increasing the refresh rate to the appropriate 75 Hz, but Catalyst won't let me, and overriding with xorg.conf does nothing.
