Removing the Trapezoidal Distortion of the Image

A “Vert. Keystone” display appears on the screen, and the projector goes into the KEYSTONE MODE.

Notes

•The range where the trapezoidal distortion can be rectified is 30˚ vertically and 10˚ horizontally with respect to the projector screen. However, when both are rendered together, the range of effective rectification will be narrower.

•Depending on the signal inputted, the keystone adjustment range may narrow or parts of the image may disappear. This is not a mal- function.

•Interference patterns may appear on the screen when adjusting the keystone. This is not a malfunction.

•To restore the original set value, press the PRESET button. (Adjusted value: 0)

Press H-KEYSTONE / to adjust in the horizontal direction.

A “Horiz. Keystone” display appears on the screen, and the projector goes into the KEYSTONE MODE.

Press button (/ ) in the direction that corrects the trapezoid form.
