Sharpness adjustment greyed out on my 2007WFP OSD?

The sharpness adjustment on my 2007WFP is greyed out so I can't adjust the sharpness. Does anyone know why? I can't stand the blurry text and have both an A00 and a replacement A02 in front of me and the text looks equally blurry on both. I've tried swapping video cards (ATI and Nvidia), auto adjust, turning off/on cleartype, changing font DPI, and nothing works. My text on my Dell laptop and the 19" Dell i use at work is sharp and clear--the text on this 2007WFP is definitely not and it hurts my eyes. Thought i'd try adjusting the sharpness as a last resort but that isn't even an option.

I'm just going to buy a Viewsonic tomorrow and compare side by side. It's an aethetically uglier monitor, but I may have to accept that if the text is better.

Any thoughts? Thanks!
