Use the formulae on the user's manual (page 51 -UK version-, "Projection dimension calculation methods").

I own a 92"x52" screen (105.5" diagonal).


Here are the formulas taken from the manual:

SD = Screen Diagonal measurement

Units = meters

Screen Width: SW=SDx0.872

Screen Height: SH=SDx0.490

Minimum Projection Distance: LW=1.42xSW-0.02

Maximum Projection Distance: LT=1.70xSW-0.08

Image Lower Edge from Lens Center: H1=SW/32


Running my numbers through those calculations, I came up the following:

SD (meters) SD (inches) SD (Feet)

2.68m=105.50"=8.79'


Screen Width: 2.34m=92.00"=7.67'

Screen Height: 1.31m=51.70"=4.31'

Minimum Projection Distance: 3.30m=129.85"=10.82'

Maximum Projection Distance: 3.89m=153.25"=12.77'

Image Lower Edge from Lens Center: 0.07m=2.87"=N/A


So, for my screen, I should optimally place the projector between 10.82' and 12.77'.


Regards,

Ken
