Keystoning occurs when the projector is not perpendicular to the screen and is where the projected 
picture displays visible as a trapezoid shape like either of the following:

•  Two parallel sides (left and right, or top and bottom) but is noticeably wider on either side.
• No 

parallel 

sides.

To correct the picture’s shape, you can perform the following steps.
1. Adjust the projection angle. Move the projector to be in front of the center of the screen with the 

center of the lens level with the screen.

2. If the picture is stilled distorted, or the projector is unable to be positioned as described above, you 

will need to manually correct the picture.

i. Press one of the Arrow/Keystone keys on the remote control 

or  projector  (Left 

/ ,  Up 

/ ,  Right 

/ ,  Down / )  to 

display the Keystone page.

ii. See step 

 below for further operation.

i. Press MENU on the projector or MENU/EXIT on the 

remote control, and then press  /  until the Display menu is 
highlighted.

to 

highlight 

Keystone and press ENTER. The Keystone page is displayed.

iii. Highlight 2D Keystone and press ENTER. The keystone correction page is displayed.
iv. Press the key whose keystone icon is opposite to the shape of the projected picture. Continue 

pressing the same key or press the other keys until you are satisfied with the shape.

The values on the lower portion of the page change while pressing. When the values reach their

not be able to change the picture further in that direction.
