I hooked up my Think Pad laptop to an Epson EMP-74 and the image projected is upside down. How do I fix?

Hi,
Do the following for setting the screen.
1. Press the Menu button
2. Select Projection
In the Projection option,
Select Front : When the projector is in front of the
screen.

Select Front/Ceiling : When the projector is in front of the
screen and suspended from the ceiling.

Select Rear : When the projector is behind the
screen.
Select Rear/Ceiling : When the projector is behind the
screen and suspended from the ceiling.
