I have the ASUS EP 121 Slate, and when I first set it up I had the same problem. The display default is set to display at 125%. To change this (on Windows 7 Pro), go to Control Panel-->Appearance and Personalization-->Display and choose "Make text and other items larger or smaller". Choose "Smaller - 100%" not "Medium - 125%". That should allow you to see the whole window.
