Correcting Image Shape with Corner Wall

You can use the projector's Corner Wall setting to adjust the shape of an image projected on a surface with right angles, such as a rectangular pillar or the corner of a room.

Note: For the best results, move the lens position to the home position and adjust the image shape based on the point nearest to the center of the screen. If a large amount of adjustment is performed, the focus may not be uniform even after making adjustments.

Turn on the projector and display an image.
Note: You can display a pattern to aid in adjusting the projected image using the Settings menu.

Note: You can also display the pattern by pressing the Test Pattern button on the remote control or the test pattern/down arrow button on the control panel.
Press the Menu button.
Select the Settings menu and press Enter.
Select the Geometry Correction setting and press Enter.
Select the Corner Wall setting and press Enter.
Note: If you see a confirmation message, press Enter.
Select the Corner Type setting and press Enter.
Select one of the following:
- Horizontal Corner when the surfaces line up horizontally
- Vertical Corner when the surfaces line up vertically
Press the Esc button to return to the Corner Wall menu screen.
Select the Correct Shape setting and press Enter.
Adjust the projector's position and use lens shift to center the image over the point where the two surfaces meet. (The rest of these steps show Horizontal Corner as the selected Corner Type but the steps are the same for Vertical Corner.)

Note: You can press Enter to show or hide the image and grid to check the results.
Press the arrow buttons on the projector or the remote control to select the area you want to adjust. Then press Enter.
- For horizontal corners, adjust the top area using the lowest point (indicated by the blue arrow) as your reference. Adjust the lower area using the highest point (indicated by the pink arrow) as your reference.
- For vertical corners, adjust the left and right areas using the points nearest the center of the image as your reference points.
Note: To reset your adjustments, press and hold the Esc button for at least 2 seconds to display a reset screen. Then select Yes.
Press and hold the arrow buttons on the projector or remote control to adjust the image shape.
Repeat the previous two steps as necessary to adjust other image areas. If the image expands or contracts, continue with the next step to adjust the linearity.
Press the Esc button to return to the Corner Wall screen.
Select the Linearity setting and press Enter.
Adjust the linearity by doing the following as necessary:
- Press and hold the left arrow button to contract the distance between the lines closest to the left or top of the image.
- Press and hold the right arrow button to contract the distance between the lines closest to the right or bottom of the image.
When you are finished, press the Menu button.

Note: If necessary, you can adjust the image tilt using the Quick Corner setting, then fine-tune your adjustments using the Point Correction setting.
