Your monitor display text size is NOT set to Smaller 100% and is instead using one of the medium or larger settings: 125%, 150%, 175%

Close Sage 300 CRE, change your display text size to Smaller 100% and log out of Windows and back in to apply the display settings. You may want to adjust your screen resolution size to offset the smaller display text size.
