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.
