To correct keystone distortion, press the KEYSTONE button.
Two types of correction are available: horizontal/vertical correction and corner 
correction.
Horizontal/vertical keystone correction adjusts image width and height, and corner 
correction adjusts the image relative to each corner.
For instructions on switching between the two types of keystone correction, refer to 
“Specifying Keystone Correction” (

). Press the KEYSTONE button to correct 

distortion according to the selected keystone correction method.

■ Horizontal/Vertical Keystone Correction

• Keystone can be adjusted within a range of approximately ±20° (WUX450/WX520) or 

approximately ±12° (WUX400ST/WX450ST). If the keystone distortion is too large to 
adjust, move the projector installation position so that it is completely straight.

• The result of keystone adjustment is stored in memory. If you place the projector in the 

same position, the keystone adjustment is not necessary.

• Signals are processed digitally when keystone distortion is corrected. The image may 

look different from the original one. In addition, the aspect ratio of the image may 
change.

• Keystone correction may not be effective in some lens shift positions.
• The digital image shift function (

screen aspect is [4:3 D. image shift] or [16:9 D. image shift].

[Zoom] (
