Well, the senior ATI tech that tried to help me was stumped. I updated him that I had tried HDMI and been able to run at 1920x1080 without the error, but the colors and contrast via HDMI were simply "off" and over-saturated. This is not an issue with the color settings. It is some kind of issue that the connection is causing. I have no idea what it is. Anyhow, I am experiencing underscanning when I run games via HDMI, but no underscanning when I'm using the benchmark utility. When I use the DVI connection, the refresh rate shows 60Hz, when I use HDMI it shows 59Hz. When I check "Information" in my monitor itself, it says 60Hz. When I use the BenQ monitor driver the "Maximum reported refresh rate" in CCC says 85Hz. When I use the default Windows monitor driver, the "Maximum reported refresh rate" in CCC says 75Hz.
