The projector is capable of correcting for keystone (trapezoidal) 
distortion caused when the projector is tilted upward or 
downward from its normal horizontal position. This feature 
corrects keystoning by making the width of the top and bottom 
of the screen the same. Access this feature using the Image 
Control selection of the on-screen display (OSD) menu. Refer 
to Chapter 3, “Using the On-Screen Display Menu” for more 
information. The keystone effect can be corrected when the 
projector is tilted upward up to 30 degrees or downward up to 
40 degrees.
Adjusting the Image Size
The projector zoom feature is capable of increasing the image 
size up to 20%. To increase the image size, turn the projector 
zoom ring toward the left 
1. To decrease the image size, turn the 
projector zoom ring toward the right 
2.
