I am using ATI catalyst control center with windows 7. the update doesn't have the manual screen stretching option so that the display wills every inch of my monitor (I have a black frame). Is there a hidden stretch function?
Its a scalling option you need to use the issue is W7 specific.
Open up CCC. In the top left corner is a drop down, go to "Desktops & Displays". You should see your monitor in the lower left, right click on it and "Configure". Then look for "Scaling Options" near the top and scale it up until the border goes away.
