Throw Ratio Cont.

You need to pay attention to your aspect ratio if you are using 4:3 because most new projectors native resolution is 16:9.  0.5:1 is easy math in 16:9 but it changes when you put your projector into a 4:3 aspect ratio.

To simplify all of this math, head over to Projector Central they have a fantastic throw calculator that can easily determine the mounting position of your projector for any given screen size.  Don't forget to select your correct aspect ratio in the drop down!
