How far back should i place the pj (Electrohome Marquee 8501) from the screen for the following desired screen size(16:9)....84.8†x 47.7 I plan on using a parkland plastic piece for the screen.....If you can get me the calculation it would be greatly appreciated. I might use a bigger screen if i have enough throw distance

Thanks
