Removing the Trapezoidal Distortion of the Image

Depending on the angle of projection onto the screen, the image may get
distorted in a trapezoid form sometimes.
When installing the projector or screen for the first time, or when reinstall-
ing in other rooms, etc., Keystone adjustments need to be made to re-
move trapezoid distortions.

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.
• The picture quality may deteriorate when performing KEYSTONE
compensation. It is recommended to place the projector perpen-
dicularly to the screen.
• Depending on the signal inputted, the keystone adjustment range
may narrow or parts of the image may disappear. This is not a
malfunction.
• 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 when
adjusting the [V-KEYSTONE] and [H-KEYSTONE]. (Adjusted value:
0)
• During startup of projector, the KEYSTONE adjustment is not re-
flected in the D-ILA logo, user-set logo (when user-set logo is se-
lected) display and the no signal blue back display.
