Then sharpen the image
by rotating focus knob.
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.
