Selecting the Aspect
Select [Aspect] based on the input signal type, aspect ratio of the screen and 
resolution.
For more details about aspect ratios, refer to “Relationship between Aspect 
and Screen Aspect” on page 287.
Types of Aspect Ratios
Auto
An image is projected at the aspect ratio of the input signal. Select this mode for 
normal image projection.
16:10
The image is projected using an input signal aspect ratio of 16:10.
Select this if an image of 16:10 aspect ratio cannot be correctly projected in [Auto] 
mode.
16:9
The image is projected using an input signal aspect ratio of 16:9. Select this if an 
image of 16:9 aspect ratio cannot be correctly projected in [Auto] mode.
4:3
The image is projected using an input signal aspect ratio of 4:3. Select this if an 
image of 4:3 aspect ratio cannot be correctly projected in [Auto] mode.
Zoom
This cuts the upper/lower or left/right part of the screen according to the screen 
aspect and zooms in or out of the center of the image. Select this if a letter box is 
displayed (black lines at the top/bottom of the screen) when watching video.
Tr u e  s i z e
The image is projected with the original resolution of the input signal. Select this 
option for clear projection of computer screens at up to maximum resolution.
There may be some cases when this cannot be selected, depending on the input signal

Step 5 Correct the Image Distortion
Adjusting Keystone Distortion
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” (P150). Press the KEYSTONE button to correct 
distortion according to the selected keystone correction method.
■Horizontal/Vertical Keystone Correction
1Press either the KEYSTONE button on the remote control or the 
KEYSTONE button on the projector to display the window shown below.
• 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 (P63) is accessed when this button is pressed and the 
screen aspect is [4:3 D. image shift] or [16:9 D. image shift].
[Zoom] (P149) in the [Install settings] menu is not available during horizontal/vertical 
keystone correction (WUX400ST/WX450ST).
