How can I correct a rotated screen on a Panasonic Toughbook CF-30 running Windows 7 Pro?

Question

My wife placed a stack of papers on her open and running (Windows 7 Pro) Toughbook CF-30. When she removed the papers the screen had been rotated 90 degress counter-clockwise. Turning the computer off and on does not reset the screen.

I have searched for the key combination that has this effect and have not had any luck. Those few that I have found and tried do not work.

Can anyone here provide an answer to reset the screen orientation to normal?

Answer 1

Hot Keys for display control (if enabled are): ctrl+alt+arrow (up 0-degrees /down 180-degrees/left 270-degrees/right 90-degrees as required.)

However, one must be logged in for these to work. My mistake was trying to apply this change while the computer was locked by the user.
