Follow below picture to adjust the focus and trapezoidal screen.
Adjust the focus by turning the knob while observing the image pixels near the center of
the screen. Optimal focus is obtained when the pixels are clearly visible. Depending on
the projected screen size, the focus near the screen edges may be less sharp than the
screen center.
Keystone image is created when the projector lens is projected from above or below the
center of the screen. Keystone correction restores the distorted image to a rectangular
or square shape.
