I just received my monitor (Rev A02) and I'm trying to make adjustments to the picture.  The user's manual shows the adjustment menu and the first selection is "Brightness and Contrast."  Mine only says "Brightness" and when I select it, that is the only option.  I've searched through all the other menu options and there is no option for setting the Contrast.  I assume there should be a Contrast setting option.  Can anyone else confirm whether or not they have this option?  If not, how am I supposed to adjust the contrast?  Thanks.
