Repeat the steps above until the top of the image is parallel with the screen.
If the upper-left corner is inside the screen after adjusting, rotate the front-left feet and the back left foot counterclockwise to the same height, and rotate the AWOL VISION 4K TriChroma
laser counterclockwise, to make the image parallel with the screen.
5. Fill The Top of The Image to The Screen
If the top of the image is wider than the screen, then rotate the left- and right-front feet of the AWOL VISION 4K TriChroma laser clockwise.
If the top of the image is narrower than the screen, then rotate the left- and right-back feet of the AWOL VISION 4K TriChroma clockwise, until the left and right borders of the image are
parallel with the screen borders.
Next, move the AWOL VISION 4K TriChroma laser further from the screen to fill the image to screen width.
If the back feet are already at their maximum height, rotate the left- and right-front feet counterclockwise.
