Cracked Screen

Hello,

I cracked my laptop screen and now i cant see on it. Well I attached another monitor to my laptop and i was able to see but when i went to the guess side it shows over on that side. Now all of a sudden it doesn't show on the administrator side which is me. I can only see now on the guess side only and i have documents on my administrator side. How can I get this dell monitor to show on both user side?

Thanks
