The projector is capable of correcting for vertical 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.

The projector can also correct for horizontal keystone (trapezoidal) distortion caused when the projector is not placed perpendicular to the screen. This correction can also be made using the Image Control selection of the OSD menu.

Adjusting the Image Size

The projector zoom feature is capable of increasing the image size up to 20%. To increase or decrease the image size, turn the projector zoom ring left or right.
