For projection applications where keystone correction is required, continue with the following
steps:
6. If the projector has an AUTOSET or AUTODETECT feature, disable this function.
These projector modes may cause image distortion if a keystone-corrected image is
applied to the projector input.
7. Select the “Advanced” menu from the TheaterSync OSM, then select “Projection”, and
“Horizontal and Vertical Keystone” submenus.
8. Using the up/down arrow keys, select in turn each of the image corner sliders and then
use the left/right arrow keys to move the corner to the desired location on the screen.
Continue adjustments until the projected image matches the target screen geometry.
