With the previous version of the AMD drivers I was able to underscan just a bit to get everything perfect on my TV. Now I can't find the position options and when I set the underscan to the max (15%) horizontally almost 20% of the screen is off the edges and there is a black bar on the top and bottom. I think I have gone through every setting in the catalsyt control center and I can't find any option for adjusting position, and I can't find the position controls assuming I could get the size scaled right. I have the a Radeon HD 6450 and have it connected via HDMI to the Mitsubishi 73" TV. Someone please help.
