I just got a Dell 2007Fbp 20" monitor. When set to the OSD defaults, the screen appears a little fuzzy next to my other Dell flat screen, a 2001FP. So I thought it might help to adjust the sharpness, but the monitor will not let me adjust several of the settings in the menu, including wide mode, sharpness, and zoom. This is true whether I have either the VGA or the DVI video input active. Does anyone have any ideas why this might be?
