Epson EX51 사용자 설명서

When projecting from the front, you should place the projector 
directly in front of the center of the screen, facing the screen squarely. 
The center of the lens should be about level with the bottom of the 
screen.

If you place the projector below screen level, you may need to tilt it up 
by extending the front adjustable foot. Tilting the projector causes the 
image to become “keystone” shaped, bu/t you can correct the 
distortion (see page 47). The EX51/EX71 may be able to correct the 
distortion automatically.
