My Sharp Projector In Not Taking Input Why Is My 'SHARP' Projector Not Displaying The Complete Screen Picture Of The PC?

Why is my 'SHARP' Projector not displaying the complete screen picture of the PC? - my sharp projector in not taking input

I am with a sharp business projector with my desktop, but does not show the complete picture on the screen. I'm sure this has nothing to do with the physical parameters, as I have already tried all the possibilities. Even if I move the mouse on the side of the screen is not displayed on the screen and from the opposite side of the screen. The same problem occurs even when the writing-only display.
