Hello, I have 1920x1080 @60Hz monitor and a AMD Radeon HD 6670.While running in 1080p I found text and other items to be to small to read; but when I changed the resolution to 1600x900 and then went to scaling options the Underscan/Overscan Slider was greyed out, making it impossible for me to force the display to take up the entire screen space. I'm using the 12.6 drivers
