The distance from the unit lens to the screen determines to the size of the projected image, therefore, you need to consider the place where you
set up the unit and screen before making connections. You also need to consider the screen size and height of the unit and screen as other
important factors.
Tip
A non-glossy wall may be used as a substitute for a screen.
