NOTES: 1) If it is necessary to make mirror adjustments do so only after you have completed this procedure.
2) Start with the displays in the center of the bottom row and work towards the end of the row.
1. Work from the back of the display cube. Make sure you can see all 4 sides of the image on the inside of the
screen.
2. Adjust the lens for best image focus on the screen. See
page 4-5.
3. Press Test on the remote once to display the internal geometry test pattern. The image on the left in the
illustration below provides an example of what you will observe after installing the light engine and before
any adjustments are made.
4. Make the following adjustments for each display to achieve the image shown on the right in the illustration
below. The edge of the test image should be within 5 mm (0.2") of the perimeter.
a. Adjust the vertical and horizontal position of the image until it is centered on the screen.
b. Zoom the image until it fits just inside the borders of the screen.
c. Adjust vertical and horizontal keystone, and tilt.
5. Once the image is geometrically aligned with the screen, as illustrated below in the image on the right,
zoom out until the edge of the test pattern is evenly aligned along the edges of the screen.
6. If necessary, readjust lens focus.
7. For each screen make sure image geometry matches between each display.
These adjustments usually require a second person in front of the display providing feedback and guidance with
display to display alignment. Start with the displays in the center cubes in the bottom row and work towards the
ends of the row. Then start with the next row in the same way.
a. Zoom out the image until it completely fills the screen.
b. If necessary, repeat step 4.
c. Repeat steps 1 to 6 for each display.
