Fine–tune image geometry using the mirror
This section outlines how to make fine adjustments to the image geometry using the mirror
adjustments such as when the edges of a single corner do not properly line up to the screen, or
when a side of the image bows in or out slightly. Guidance for fixing specific issues follows the
general instructions for mirror adjustments. Mirror adjustments should only be performed if
absolutely necessary.
You can also use the mirror to correct slight misalignments
between projected images where the edges align properly
with the screens, but adjoining images do not line up
correctly.

Adjusting the mirror screens is for very fine geometry alignment around the edges of the display.
Adjust the mirror only if absolutely necessary. The illustration below shows the locations of
adjustment screws on the mirror and the corresponding zone on the screen that they affect. Use
