Adjust The Focus And Keystone
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 beam is projected to
the screen in an angle. Keystone correction will restore the distorted
image to a rectangular or square shape.
