Examples of 4:3 images displayed with different aspect ratio settings
The 4:3 setting is best, unless there is some specific reason for wantin\
g the smaller 
Native image, for instance, to maintain the same scale as other images f\
rom the 
same source.
If you are using an anamorphic lens, the 4:3 Narrow setting should be us\
ed. The 
lens will stretch the image to the correct width.

Diagonal screen sizes
Screen sizes are sometimes specified by their diagonal size (D) in inc\
hes. When 
dealing with large screens and projection distances at different aspect ratios, it is 
more convenient to measure screen width (W) and height (H).
The example calculations below show how to convert diagonal sizes in inc\
hes into 
width and height, at various aspect ratios.

Fitting the image to the screen
It is important that your screen is of sufficient height and width to display images at 
all the aspect ratios you are planning to use.
Use the conversion chart, or the sample calculations below to check that\
 you are 
able to display the full image on your screen. If you have insufficient height or width, 
you will have to reduce the overall image size in order to...

Positioning the screen and projector
Optimum viewing position
For optimum viewing, the screen should be a flat surface perpendicular t\
o the floor. 
The bottom of the screen should be 1.2m (4 feet) above the floor and t\
he front row 
of the audience should not have to look up more than 30° to see the t\
op of the 
screen.
The distance between the front row of the audience and the screen should\
 be at...

Screen size vs throw distance
Throw distance is the distance measured from the front of the projector \
to the 
screen. This is an important calculation in any projector installation as it det\
ermines 
whether or not you have enough room to install your projector with the d\
esired 
screen size, and if your image will be the right size for your screen.

Notes
 The Throw ratio for a particular 
lens is fixed, but assumes that 
the image fills the width of the 
DMD.
  For images that do not fill the 
width of the DMD, the Throw 
ratio is effectively increased. 
To correct for this in these 
calculations, a Throw Ratio 
Factor (TRF) is used.
 
  ONLY the High Brightness 
lenses are recommended for 
the 1080p 330.
